'Powdery mildew can be a problem in drier growing seasons'



Example 18 - Field trials of Encapsulated Terpene Composition on Powdery Mildew
Powdery mildew of grapes is caused by the fungus Uncinula necator, and causes reductions in vine growth, fruit quality and winter hardiness of vines. In wine grapes, an infection level of only 3% of berries can affect wine quality. The disease is characterised by small white-grey patches of fungal growth that enlarge into a powdery, white coating on the leaves. The fungal growth can also occur on the berries, which may split. In contrast to downy mildew, which requires warm wet conditions, powdery mildew can be a problem in drier growing seasons, as it favours shaded areas with humid but not rainy weather conditions. Preventative measures are recommended for management of powdery mildew, with early applications of fungicides followed by repeat applications at appropriate intervals.
This study aimed to investigate the efficacy of application of the YGP-GET composition for the prevention of powdery mildew in grapes. Three adjacent blocks, each covering 0.1 ha, were identified on site 18 in the Kir-Yianni vineyard. On 19 July 2004, one of the three blocks was sprayed with the YGP-GET liquid formulation at a dose of 2 ml/L and one was left untreated. The remaining block was sprayed with the conventional treatment of Equesion (2.5 g/L), Alliete (0.9 g/L) and Punch (0.075 ml_/L) (see Fig.22). The vines in each block were monitored for signs of powdery mildew over the following week.

Three further adjacent blocks, each covering 0.1 ha, were identified on site 20 in the Kir-Yianni vineyard. On 20 July 2004, one of the three blocks was sprayed with the YGP-GET liquid formulation at a dose of 2 ml_/L and the two remaining blocks were left untreated (see Fig. 22). The vines in each block were monitored for signs of powdery mildew over the following week.
At both sites, the blocks had previously been treated with multiple products, including a prior application of terpene product.
All terpene treatments were applied at a rate of 1200 L/ha to ensure complete coverage.
The following growth stages of the grapes were recorded bud break, 26 March 2004 bloom, 1 June 2004 veraison, 6 August 2004
The study applications took place pre-veraison. The 2004 growing season was exceptionally late and was wet throughout. Disease pressure from downy mildew was extremely high, botrytis levels were elevated, and powdery mildew pressure was moderate.


Details of Comparator Products
No comparator product was used at site 20. The comparator treatment used at site 18 is detailed below.
Punch® (flusilazole 40%), DuPont.
On 19 July 2004, Punch was applied at a dose of 0.075 ml/L as a preventative treatment for powdery mildew according to the manufacturer's instructions.
Details of Additional Products
No additional products were used at site 20. The additional products used at site 18 are detailed below.
Equesion system (famoxadone 22.5% plus cymoxanil 30%) Alliete (fosetyl-al 80%)
On 19 July 2004, Equesion (2.5 g/L) and Alliete (0.9 g/L) were applied as preventative treatments for downy mildew. The dose was determined according to the manufacturer's instructions.
The comparator and additional products represent conventional treatments in the integrated pest management schedule.
Vines were visually examined for symptoms of powdery mildew.

Results: Site 18
Approximately 20% of the peduncles and stems in the control block were black, indicating moderate infection from powdery mildew. In both the conventional treatment block and the terpene-treated block, all stems and bunches were green, indicating that adequate protection had been provided.
Site 20
No evidence of powdery mildew infection was observed in any of the blocks.
Additional observations
At the end of the growing season, the blocks at sites 18 and 20 generally showed less stress due to disease than the rest of the vineyard.
Powdery mildew infections cause considerable losses to growers through reductions in vine growth, fruit quality and winter hardiness of vines. Furthermore, wine quality can be affected by an infection level of as little as 3% of berries. Management of the disease focuses on prevention because, once established, the infection can quickly spread. In this study, the application of terpene product YGP-GET at site 18 effectively prevented powdery mildew infection, and the level of control exhibited by the terpene product was comparable to that provided by the conventional treatment. The results from site 20 are inconclusive, however, due to the lack of powdery mildew infection. This lack of infection is likely to be due to the extensive application of pesticides prior to the study, which resulted in low disease pressure. The lower level of stress due to disease at sites 18 and 20 suggests that the earlier terpene treatment applied at these sites may have been beneficial in control of infection in the long term.

Conclusions:
YGP-GET effectively prevented powdery mildew infection, with a comparable level of control to that provided by the conventional treatment.

Timorex Gold vs 3AEY.

From lay person scanning this:
in relation to the above my assessment is that 3AEY is a superior product.

Here's why IMO:

Timorex contains Tea Tree Oil (TTO)and Ethanol, it has toxic characteristic which are mitigated in the greenhouse by the absence of birds and Fish etc. In the field these characteristic are mitigated because it volatises/evaporates within 24hrs.

The toxicity of TTO means it is an irritant and workers need eye and body protection when spraying.

Also although it is not flammable, due of the Ethanol component it has to follow flammable liquid storage rules.

The inherent volatility means it has a short action window of approx 24hrs and can be sprayed up to 3 times per season with 7 day minimum intervals.

3AEY. The volatility of the terpenes is harnessed by the encapsulation technology which releases the active substances at times when plants ambient conditions are vulnerable for fungal growth. This slow release action means 3AEY stays on the plant, it's action is multiplied and environmentally triggered which means it is longer lasting than Timorex..so less spraying needed and potentially more potent and ready for action at vulnerable times.

No protective clothing needed when spraying.

Although Timorex has no MRL's it also I believe has no anti fungal value to the farmer post harvest due to volitisation so here again 3AEY has the advantage.

all IMHO.

Thank you.

Littlealbatros,

I think Sean Smith mentioned a possible deal regarding Lachlan ( I may have misinterpreted this) and an Israel company. To my knowledge ,I don't think Timorex was mentioned.

Re Timorex Gold, from reading this assessment;



I wonder if TG meets EU organic and MRL standards as 3AEY clearly does..and some of the concerns raised here would be scrutinised more closely during EU registration ie estrogenic and anti-androgenic activities and toxicity etc. (I am a complete novice in this area so know nothing)

[littlealbatross2] 29/7/2017 16:55

Very interesting finds supers.
Might Timorex-Gold be a competitor to 3AEY as you suggest?
In ecology, inter-specific competition between two different species for the same resource has 3 outcomes: 1.One wins totally and drives the other out. 2.One wins and lives at a much higher level with the loser living at a much lower level. 3.Both co-exist at slightly lower levels.
Which outcome will it be if indeed there is a direct clash between Timorex-Gold and 3AEY!
Do you know what Sean Smith said re Stockton/Timorex-Gold at the AGM?

[supersonico] 29/7/2017 08:00

Stockton are an Israel company I think..are they the company that Sean Smith talked of at the AGM looking at buying Lachlan @ Kenya ?

If they are then will they be a competitor in the same market.??

Locally here in the Pas de Calais the farmers have been complaining about such things as barley ripening too small and early which will reduce the quantity they can obtain per hectare by quite a lot.
Presumably maize and wheat might be the same.

[investingisatrickygame] 23/7/2017 22:49

supersonico,

Thanks for putting up all of this information.

With crops so badly affected it is easy to make a case for protecting against Botrytis, should conditions leading to that exist or in some cases, write the year off and not bother. There is likely a cost/benefit consideration in there, especially for someone who has been affected with up to a 90% loss.

One thing is for sure though in my opinion. With Sumi and Sipcam having a New Product Launch (NPL) with 3AEY this year, sales from us to them should be good because there is no way they will wish to be caught short on an NPL. That would be a cardinal sin!

As reported by The Telegraph, half of the territories in Spain have been put on a state of alert due to the drought, which has been gathering pace since last year.
Reservoirs across the country are currently standing at 56% – their lowest for this time of year since 1995, with rainfall at less than half the historic average. Farmers across Spain are calling it the worst year for agriculture in decades after the hottest April this century.

Winemakers are facing the double whammy of severe late spring frost damage coupled with scorching summer temperatures. According to Spanish newspaper El Confidencial, the grape crop is predicted to be down by half in some regions.
“We are facing a complicated year, the prediction is that production will drop, but a lot depends on the second part of the year,” said José Joaquín Vizcaíno, the Agricultural Committee’s representative for the wine sector.
While yields are likely to be down, quality too could be affected if temperatures continue to soar, as the grapes will dry out and become over-ripe, leading to hot, unbalanced, high-alcohol wines.
Pablo Dominguez, a Tempranillo grower in the province of Zamora, has already lost up to 90% of the grapes on parts of his land due to the April frosts. “We are already in July and it doesn’t look like this is going to get better,” he told El Confidencial.

The spring frosts also wreaked havoc in Spain’s key wine region – Rioja.
“The frost damage was very bad in Rioja – Rioja Alta and Alavesa were worst hit. People have been speaking about damages to their vines of up to 50%,” Carlos Delage, export area manager of Cune told db.
“Those who will struggle most are the producers making entry-level wines. These were the worst frosts in Rioja since 1999 and we’re expecting grape prices to rise off the back of it,” he added.
Around 70-80% of vineyards in Bierzo, northwest Spain, were damaged by the frosts, while over 70% of vines in Galicia were affected.

Paris plays transparency on endocrine disrupters

Ten days after agreeing to the European criteria for the definition of substances affecting the hormonal system, France published two lists of 1,600 biocidal preparations and pesticides that could be classified as endocrine disruptors in the future. A rare step. An article by our partner, the Journal of the Environment.
A thousand biocides (insecticides, wood preservatives and veterinary hygiene) and some 600 pesticides (insecticide, herbicide, fungicide). The ministries of agriculture and ecology published on July 13 the names of products authorized in France "likely to contain endocrine disrupting substances". A transparent operation that comes just 10 days after the turnaround of France on the adoption of criteria for definition of endocrine disruptors. The ministers then spelled out national measures (see box) that were supposed to counterbalance the concessions of a text that Nicolas Hulot himself had described as "insufficient in the present state".

New criteria
France boasted of obtaining "additional guarantees obtained" from the Commission. Namely the immediate application of the new criteria to substances under re-evaluation at Community level; The launch of a European strategy taking into account all possible exposures, in particular in toys, cosmetics and food packaging; The mobilization of a further EUR 50 million for research into the effects of endocrine disruptors as early as 2018; The rapid presentation of an evaluation of the efficiency of these criteria and the effect of the exemptions introduced.
Products to be checked
And it is, pending the "concrete entry into force of the European exclusion", citizens, farmers and professionals "can guide their purchasing choices", that these 2 lists have been published. Attention, warn the ministries: the scientific agencies have not yet carried out the detailed work of verification, substance by substance, of their endocrine disrupting nature. Some 1,600 preparations contain one or more active substances, as reported by the Joint Research Center of the European Commission (JRC). The July 4 definition is "wider, including suspected endocrine disruptors, and substances for which endocrine disrupting action is 'plausible'." Consequently, substances may therefore no longer be included in this list after detailed analysis by the European health agencies. Conversely, other substances not identified to date can be integrated later.

Specify the active substances used
This situation does not satisfy anyone. The association Générations Futures points out that if the list of biocides and pesticides published "seems long", it concerns only commercial products. "It is now necessary for the ministries to publish the list of active substances concerned so that we can see more clearly," says François Veillerette, his spokesman. Furthermore, associations are very suspicious of the scientific guidelines being developed, which could further alter a definition that they consider already insufficient for the protection of public health and the environment and, in the end, Restrict the list of products to be avoided.
Respect the European process
The Union of Industries for the Protection of Plants (UIPP) expressed its indignation at the publication of these two lists. "The government is not respecting the European decision-making process currently under way ... It is premature to date to translate the draft definition into a list of substances", all the more on the basis of "preliminary work And superficial, which has nothing to do with the necessary scientific assessments expected by our fellow citizens.

On Wednesday, June 21, 2017, from 9:30 am, in Conegliano (TV), in the magna hall of the University (via Dalmasso 1), will be held "Veneto vineyard, trend and production forecasts 2017", the first focus of the Triptych Vitivinicolo Veneto organized by Veneto Agricoltura-Europe Direct, with Veneto Region, CREA-VIT, ARPAV and the collaboration of CIRVE-University of Padua.
Very early anticipations. Due to the current climate, characterized by sunny and high temperatures, the 2017 harvest is announced an advance of ten days compared to the average. The confirmation in the Veneto comes from the early varieties (Chardonnay and Pinot), which are already in the early stages of cluster closure. As far as vineyards are concerned, almost everywhere in the Veneto there are abundant leafy exuberances that need to be "controlled" with cuttings and bindings. The health of grapes is at the moment great. These are the first advances in the coming grape harvest, obtained from the data collected by a "network" of operators who are responsible for some wineries and consortia of the various wine areas of Veneto and elaborated by the promoters of the event.

Ice cream in April will affect production? For some years, the three events of the Triptych Vitivinicolo Veneto (scheduled in June, August and December) are important moments of comparison to photograph and analyze the sector at the crucial stages of vintage wine. With this triple initiative it is intended to keep track of the Veneto vineyard from the early stages of the fruit growing (June meeting), at the start of grape harvest (August) until the end of the harvest (December). At the meeting held in Conegliano on 21 June, the vegetative and phytosanitary status of the Venetian vineyard at the beginning of summer will be discussed, also in relation to the first half of the year, which was characterized by a strong ice cream recorded during the month of April, whose damages at this time are not yet quantifiable given the different varietal reaction. To date, however, it is evident that some varieties, such as Merlot, have recovered better than others, such as Teroldego.

France: towards a vintage "historically low" after the spring frosts
Agriculture
Bordelais, but also Charentes, Alsace and Jura: the French harvest in 2017 should be heavily penalized by spring gels, and the expected wine volumes could be "historically low", according to the Ministry of Agriculture.
"At 37.6 million hectoliters, the 2017 crop is expected to be 17% lower than in 2016 and 16% below the average of the last five years," Agreste, the statistics office of the Ministry of Agriculture in Its latest issue.
This harvest would then be "historically low and lower than in 1991, which is also affected by a severe freeze," the publication added.
All the wine-growing basins were affected by a severe frost in the spring. But the basins of the South-West, notably of the Bordeaux, Charentes, but also of Alsace and Jura would be the most affected. Hail losses are also expected in Burgundy-Beaujolais, South-West, Languedoc and South-East.
The vineyards around the Mediterranean are affected by another phenomenon, also linked to a weather hazard, the "coulure", that is to say the fall of flowers or young berries, due in general to an incident at Time of flowering and fertilization.
This phenomenon particularly affects the Grenache grape varieties of the Rhone valley.
In detail, wines for brandy (Cognac for example) could be the most affected by the fall of harvest:
According to the Ministry's estimates, the harvest

"August made grapes, September wine"
For PDO (Appellations d'Origine protégé;e) wines, the decline is expected to be 12%, to 18.45 million hl against 20.9 in 2016. IGP (Protected Geographical Indication) wines are expected to fall by 15% 10.89 million hl against 12.8 last year.
Finally, for wines without a geographical indication, the production decline is estimated at 27%, to 2.9 million hl against 3.9 million in 2016.
Philippe Faur-Brac, a sommelier who won the world's best sommelier contest in 1992, reminded AFP of the saying of a wine-grower: "August makes grapes, September makes wine".
"It is still too early to draw a conclusion on the quality of this year's wine, which will depend on the climate until the harvest, and the harvesting conditions. At the moment, climatic conditions are not bad at all, but The quantity, it will be economically very tense, for sure, "he told AFP.
The year 1991 was a "bad crop", not only because of the frost, but also "conditions of harvest not terrible," he argued.
The main hope of rebalancing, the systems of "reserves" practiced by certain vineyards such as Chablis or Champagne, where part of the wine is kept from one year to the next without being marketed as insurance. This makes it possible to smooth the incidence of climatic hazards.
"As 2016 was a great milestone, this will allow in some regions to regulate volumes and quality," said Faure Brac.
But all regions do not practice this system. And French winemakers are far from being insured against frost or hail: only 25% of them are.
Some properties that have "little stock", "little cash", and who have already suffered frost or hail last year will be in a "difficult" situation, says Bernard Farges, chairman of the national AOP / AOC.
"We are working with the ministry to put in place structural measures through an improvement in the insurance system and the savings tax system," he said.
These measures will not solve this year's problem. And it will be all the more difficult to manage because the appeal to the solidarity funds of natural calamity is not possible either, since these damages are theoretically insurable.
