Embodiment 1

[0035] From 2017 to 2019, in the mulberry gardens of Lixian, Changsha, Youxian and other places, the following methods were used to prevent and control sclerotinia sclerotinia:

[0036] Every year from late February to late March, spray when there is no dew on the mulberry trees on sunny days, or when there is no rain on the mulberry trees and at least 2 hours after the application of the medicine, at the early flowering stage, full flowering stage, and final flowering stage of mulberry. The liquid medicine is evenly sprayed on the mulberry, mulberry leaves and mulberry branches:

[0037] Spray with 25% prochloraz EC 500 times liquid for the first time at the early flowering stage of mulberry;

[0038] Spray with 500 times of 25% prochloraz EC + 750 times of 40% sclerotin wettable powder at the full bloom stage of mulberry for the second time;

[0039] Spray with 750 times of liquid of 40% Sclerotia net wettable powder at the end flowering stage of mulberry for the third time...

Abstract

The invention provides a method for controlling a mulberry sclerotium disease, and relates to the technical field of agricultural disease control. The method for controlling the mulberry sclerotium disease comprises the steps of prochloraz spraying in the mulberry initial flowering stage, prochloraz and dimethachlon spraying in the mulberry full-bloom stage and dimethachlon spraying at the end ofmulberry flowering stage. Accordingly, improvement is conducted aiming at the problem that an existing mulberry sclerotium disease chemical control method is not ideal in control effect and high in pesticide residue, a combination of two different kinds of fungicides is selected, the fungicides are used alternately in the optimal control period, not only is drug resistance of the germs greatly reduced and the dosage of pesticide is reduced, but also the control of the disease is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural disease prevention and control, in particular to a method for preventing and treating sclerotinia sclerotiorum.
