Problems solved by technology

[0003] At present, there are many ways to prevent and control diseases of eggplant root rot, but many of them are aimed at "curing by treatment", and the control effect is not ideal, and there is a lack of seamless control of the entire production chain
At the same time, each disease of root rot is divided and conquered, and the cost of prevention and control is increased instead.

Embodiment 1

[0038] A method for preventing and treating eggplant root rot class diseases, comprising the following steps:

[0039] Step 1, seedbed treatment: After sowing, pour the seedling-raising matrix with 800 times of liquid of 68% of manganese zinc, and then raise seedlings according to the normal seedling-raising method;

[0040] Step 2, seedbed treatment before transplanting: the day before transplanting, spray the seedbed with 1000 times of 25% prochloraz;

[0041] Step 3, pre-transplanting treatment in the field: process with Mianlong fumigant, 30kg per mu;

[0042] Step 4, post-planting treatment: after planting, use 25% prochloraz 1000 times + 80% mancozeb to pour root-setting water, 250ml liquid medicine per plant;

[0043] Step 5, before the eggplant blooms, spray the medicine or irrigate the roots: before the eggplant blooms, use 42% tebuconazole carbendazim 1000 times solution for spraying.

[0044] If the field is a field with recurrent root rot diseases in the past, us...

Abstract

The invention discloses a method for preventing eggplant root rot diseases. The method comprises the following steps that after seed sowing, refined metalaxyl-mancozeb or hymexazol or thia-pyrrole-oxadixyl dilute solution is adopted for thoroughly watering a substrate, and then seedlings are grown in a normal seedling growing mode; the day before transplanting, prochloraz or refined metalaxyl-mancozeb dilute solution is used for spraying a seedbed; a dazomet fumigant is used for treating a land for growing field crops; after field planting, a prochloraz dilute solution and mancozeb are selected for watering rooting water; before eggplants bloom, a pentodrine dilute solution is selected for spraying; if pieces of paddy field are pieces where previous root rot diseases happen heavily, the hymexazol aqueous dilute solution is used for root irrigation; other administration is performed according to normal management measures of the field. Early and small diseases can be prevented in the whole process, prevention is adopted as the main part, no control leakage period exists in the early growth period, and the eggplant root rot diseases are effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of pest control in agricultural production, and in particular relates to a method for preventing and controlling eggplant root rot diseases. Background technique [0002] Eggplant is an important solanaceous vegetable, which is planted in a large area across the country and is one of the vegetables with high economic value. During the eggplant planting process, pathogens such as Fusarium and Verticillium dahliae often cause the root of the eggplant to wither and rot, resulting in a large area of ​​eggplant dead trees, which has brought extremely serious economic losses to the growers. Because root rot diseases are soil-borne diseases, the pathogens survive in the soil for a long time, so the difficulty of controlling eggplant root rot diseases increases. In production, soil-borne diseases such as eggplant root rot, fusarium wilt and Verticillium wilt are controlled separately. During the prevention and con...
