Abstract

The invention relates to a soil disinfectant for prevention and treatment of tomato early blight and a prevention and treatment method of the soil disinfectant. The soil disinfectant is prepared fromthe components of a walnut green seedcase extract (or walnut green seedcase extract slag), copper sulfate, quick lime, rice bran and dried poultry litter with the mass ratio being (10 to 20):(5 to 10):(5 to 20):(10 to 20):(2 to 8). According to the soil disinfectant, alternaria solani in soil can be killed, the N, P and K contents of the soil are increased, thus crops are protected against threatof soil-borne diseases, certain nutrition is provided for plant growth, operation is easy, safety is achieved, and residue is avoided.

Description

technical field [0001] The invention relates to a soil disinfectant and a control method thereof, in particular to a soil disinfectant for preventing and treating tomato diseases and a control method thereof. Background technique [0002] In recent years, with the development of intensive planting patterns, continuous planting of crops is common, and continuous cropping and repeated cropping are likely to lead to the occurrence of crop soil-borne diseases, especially in vegetables, such as pepper Phytophthora, tomato blight, tomato Fusarium wilt, early blight of tomato, late blight of potato, root-knot nematode, etc., the occurrence of diseases reduces the income of farmers. In addition, due to the lack of awareness of diseases by farmers, long-term abuse of chemical fertilizers and pesticides will lead to increased resistance to diseases. The reduction of the control effect has caused the difficulty of prevention and control, and will also cause certain residual pollution t...
