The disease cycle begins with the overwintering structures. The grape black rot pathogen overwinters in many parts of the grape vine, especially mummies and lesions, and is able to overwinter on the vineyard floor. [3] In fact, "Viable lesions capable of producing conidia can persist in wood for at least 2 years."
The disease development of grape downy mildew is known to be heavily reliant on the efficiency of the asexual propagation cycles. Kiefer et al. (2002) demonstrated that the early development of Plasmopara viticola is regulated specifically and coordinately by unknown factors originating from the host grapevine plant Vitis vinifera . [ 13 ]

Fluxapyroxad is a broad-spectrum pyrazole-carboxamide fungicide used on a large variety of commercial crops. [2] [3] It stunts fungus growth by inhibiting the succinate dehydrogenase (SQR) enzyme. [3] [4] Application of fluxapyroxad helps prevent many wilts and other fungal infections from taking hold.
Thiram is a type of sulfur fungicide. It has been found to dissolve completely in chloroform, acetone, and ether. It is available as dust, flowable, wettable powder, water-dispersible granules, and water suspension formulations and in mixtures with other fungicides. [4] Thiram is nearly immobile in clay soils or in soils of high organic matter.
Botrytis cinerea is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes.

Fungicide sprays applied in a timely manner are highly effective against the rust diseases during the apple cycle. [12] Most protective fungicide sprays are applied four times at 7- to 10-day intervals, starting with pink bud on crabapples. These applications are to protect the apples from spores being released from the cedar host in mid-spring.
