Grapevine fungicides
The objective of this Campo Demo is to show and compare every fungicidal strategy against Plasmopara viticola (downy mildew).
It is a particular fungus that develops in hot and humid environments. Symptoms include irregular yellow spots on the upper surface of the leaves (that can brown because of necrosis) and white and dusty spots on the bottom surface. On the bunches, the fruit is covered by a white/grey dust and changes color from purple to a reddish-brown.
We have tried several strategies and products, both biological and synthetic, to evaluate their effectiveness in controlling this pathogen.
Cereal fungicides
The fungicides Campo Demo aims at evaluating innovative strategies to contain Fusarium Head Blight (FHB), one of the main pathogens for wheat.
Specifically, the volume of water used and different types of nozzles will be evaluated.
Strawberry fungicides
One of the main pathogens for strawberries is Botrytis cinerea (grey mould). The goal of this Campo Demo is to show and compare every fungicidal strategy against this pathogen.
Botrytis cinerea, the causative agent of grey mould in strawberries, is a particular fungus that develops in a humid environment. The symptoms consist of grey-brown lesions and white powdery spots on the fruits.
We have tested different strategies with biological products to test their effectiveness in the management of this pathogen.
Table grape fungicides
The project for spreading techniques to optimize and improve the management of the main fungal diseases in table grapes, such as downy mildew, powdery mildew, and grey mould, continues. As for the previous editions, the need to add the grey mould as a focus for 2022 has emerged from the requests of the producers of quality table grapes. Therefore, the location for the 2022 edition of the Table grape fungicides Campo Demo will be a vineyard in the Palagiano countryside, of the “Italia” variety, which is suited for a longer commercialization window thanks to techniques that extend the time the bunches can stay on the plant and their subsequent cold storage in specialized structures.
Grapevine fungicides
The fungicide Campo Demo will be held in the Asti province, in the center of the viticultural area. The variety considered will be the White Muscat, among the most representative of the area and very sensitive to the main cryptogamic diseases.
Products with different mechanisms of actions, for biological agriculture and widespread use in the containment of downy and powdery mildew will be tested.
In order to be able to see the effectiveness of the different solutions tested, field visits are scheduled during the second half of July.
Grapevine fungicides
Evaluation on cv. Chardonnay and white Moscato of the effectiveness of protection strategies for containing downy mildew on grapevines.
Cereal fungicides
In the field, several protection strategies were tested. Regarding conventional treatments, the most widely used class of molecules was triazoles, while the biological treatments were focused on copper and sulfur-based products, as well as on antagonistic fungal agents.
Cereal herbicides
Table grape fungicides
Evaluation of several products and strategies for controlling downy mildew and powdery mildew on table grapes.
Strategies and chemical and biological products have been tested to evaluate their effectiveness on Plasmopara vitivola and Uncinula necator on table grapes.
Grapevine fungicides
Plasmopora viticola, a causative agent for downy mildew in grapevines, is a particular type of fungus that develops in hot and humid environments. The symptoms appear as irregular chlorothic spots on the top side of leaves, which could subsequently necrotize and a powdery coating on the bottom side. The fruits are covered by a whitish powder and change color from purple to reddish brown.
Uncinula necator is the cause of powdery mildew on grapevines. In hot and humid environments, it infects all the green tissues, including leaves and young bunches. The symptoms are easily recognizable and identifiable: a white-grey powder covers the infected tissues, visible on the top side of the leaves and the fruits.
We have tested different strategies and products, both biological and chemical, in order to evaluate their effectiveness in controlling these pathogens.
