Embodiment 1

[0017] A method for preventing and treating sclerotinia sclerotiorum. The application time of the same fruit mulberry variety in the same control area must start when the fruit mulberry flowering rate reaches more than 80% every spring. The verification method for the flowering rate of 80% is random observation of multiple plants. For the mulberry branches with different orientations of fruit mulberries, the style of the mulberry flower changes from cohesive and curly to stretched out and from thin to thick, and the color of the stigma also changes from green to white to bloom. Judgment is based on the proportion of bloom. During a certain period of time from 10 am to 6 pm, and the weather is fine, and there is no dew on the mulberry leaves, mulberry flowers and mulberry branches (that is, the mulberry leaves, mulberry flowers and mulberry branches are dry or the dew has been dried or air-dried) , spray the flowers, leaves and branches of fruit mulberry and make the medicinal l...

Embodiment 2

[0020] A method of preventing and treating sclerotinia sclerotiorum. In March 2017, in the fruit mulberry base of Gaoping District, three-year-old seedless big 10 was selected as the test object, and it was divided into 4 different application areas. When the flowering rate of Seedless Big 10 reaches 80%, at a certain time period from 10:00 am to 6:00 pm, and the weather is fine, there is no dew on the mulberry leaves, mulberry flowers and mulberry branches (ie mulberry leaves, mulberry flowers and mulberry branches). When the mulberry branches are anhydrous or the dew has been dried or air-dried), use 50% procymidone wettable powder 1500 times liquid, 40% sclerotia wettable powder 1000 times liquid, 70% thiophanate-methyl in 4 areas respectively Wettable powder 1000 times liquid and 50% carbendazim wettable powder 800 times liquid spray the flowers, leaves and branches of fruit mulberry, and ensure that the medicinal solution can evenly cover the flowers, leaves and branches o...

Embodiment 3

[0022] A method of preventing and treating sclerotinia sclerotiorum. In March 2017, in the fruit mulberry base of Xinmiao Township, 7-year-old Jialing No. 30 was selected as the test object, and it was divided into 4 different medication areas. When the flowering rate of Jialing 30 reaches 80%, at a certain time period from 10 am to 6 pm, and the weather is clear, there is no dew on the mulberry leaves, mulberry flowers and mulberry branches (that is, the mulberry leaves, mulberry flowers and mulberry branches When there is no water or the dew has been dried or air-dried), use 50% procymidone wettable powder 1500 times liquid, 40% sclerotin wettable powder 1000 times liquid, 70% thiophanate-methyl wettable powder in 4 areas respectively. The 1000-fold liquid of the powder and the 800-fold liquid of the 50% carbendazim wettable powder are sprayed on the flowers, leaves and branches of the fruit mulberry, and it is ensured that the medicinal liquid can evenly cover the flowers, l...

Abstract

The invention discloses a method for controlling mulberry sclerotinia sclerotiorum. The flowering rate of fruit mulberry is 80% or above in spring every year, at a certain time period between 10 o'clock in the morning and 6 o'clock in the afternoon, spraying is conducted on mulberry flowers, leaves and branches by utilizing any of 50% of procymidone wettable powder X1500 liquid, 40% dimethachlon wettable powder X1000 liquid, 70% thiophanate methyl wettable powder X1000 liquid, or 50% carbendazim wettable powder X800 medicament; it is ensured that the liquid can evenly cover the mulberry flowers, leaves, and branches. The method strictly controls the time of using pesticide, the number of times of drug application on preventing and curing the mulberry sclerotinia sclerotiorum is reduced toone, the amount of pesticide application is reduced, the reduction of the pesticide residue of mulberry is facilitated, the quality and safety of agricultural products are protected, the quality of mulberry is improved, meanwhile the production costs of labor and pesticide are reduced, ecological environment pollution by pesticide and pesticide packaging waste is reduced, and the sustainable development of fruit mulberry industry is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural pest control, in particular to a method for preventing and controlling sclerotinia sclerotiorum. Background technique [0002] Sclerotinia mulberry is a general term for hypertrophic sclerotinia, reduced sclerotinia, and small grain sclerotinia. The perianth of hypertrophic sclerotinia is thick and swollen, off-white, the disease model is enlarged, and there is a black sclerotia in the center, and the disease model emits a bad smell after being broken. The shrinking sclerotinia sclerotia is significantly reduced, off-white, hard in texture, with dark brown fine spots on the surface, and black hard sclerotia is formed in the sclerotia. Sclerotinia sclerotiorum After each small fruit of mulberry is infected, it expands, and small granular sclerotia grows inside. The diseased mulberry is gray-black, and it is easy to fall off and the fruit axis remains. [0003] At present, in the prevention ...
