Problems solved by technology

If simply relying on strengthening cultivation management or increasing the application of organic fertilizers, phosphorus and potassium fertilizers, the incidence of disease cannot be suppressed, and if the control is started in the late flowering period, it will be highly susceptible to the disease and it is difficult to completely eliminate the pathogenic bacteria

Abstract

The invention discloses a pre-blossom prevention and treatment method for gray mold of summer black grapes. The method includes: S1) during flower spike exposure period of the summer black grapes, employing fluopyram, trifloxystrobin and Scala medicines, adding water for dilution and uniformly spraying the liquid onto the grape vines; S2) in the inflorescence separation period of grapes, preparinga medicine with a thiophanate-methyl wettable powder, a feather cockscomb seed extract and sophocarpidine ferrous complex, adding water for dilution and uniformly spraying the medicine onto the grapevines; S3) in the early stage of the flower spike period of the summer black grapes, preparing a medicine with a procymidone wettable powder, carp peptide ferrous complex and a sophocarpidine zinc complex, and adding water for dilution uniformly spraying the medicine. In the method, during the flower spike exposure period, the inflorescence separation period and the early stage of the flower spike period, different medicines are sprayed for prevention and treatment of the gray mold, so that prevention and treatment efficiency is greatly increased by means of applications of the different medicines; the method can reduce diseased fruit rate of gray mold, is low in cost and is simple and available.

Description

Technical field [0001] The invention relates to the field of grape disease prevention and control, and in particular to a pre-flowering prevention and control method of summer black grape gray mold. technical background [0002] Grape gray mold is a common and difficult-to-control fungal disease. It mainly damages flower spikes, fruit spikes or fruit stems, new shoots and leaves. The lesions are light brown and irregular, water-soaked, and then turn into dark brown. The fruit ears are soft and rotten, sometimes with inconspicuous ring patterns, and a sparse gray mold layer grows on them. Low temperature and high humidity are conducive to the disease. During the grape flowering period, the temperature is not high. If it rains continuously, the air humidity is high, which often causes the flower spikes to rot and fall off. During the maturity period, due to the conversion of sugar in the fruit, the water content increases, and the disease resistance is reduced, making the dise...
