Problems solved by technology

Studies have shown that there is currently no soil fumigant that can achieve the comprehensive advantages of methyl bromide in the prevention and control of soil-borne diseases. It is a good way to achieve the control effect of methyl bromide through screening and compounding among the agents that can be used for soil fumigation. proven method

Abstract

The invention relates to wettable powder, powder or a microgranule preparation prepared from accessory ingredients, such as a wetting agent, a dispersing agent, fillers and the like, and a pesticide composition containing dazomet and 1,3-dichloropropylene for controlling soil-borne diseases such as Phytoph-thora capsici Leonian and the like as well as Meloidogyne. The invention also discloses a method for preventing the soil-borne diseases such as the Phytoph-thora capsici Leonian and the like as well as Meloidogyne by using the composition containing the dazomet and the 1,3-dichloropropylene. The dazomet and the 1,3-dichloropropylene are mixed at the ratio of (1:2)-(2:1) to especially perform action on the Phytoph-thora capsici Leonian and the Meloidogyne. The pesticide composition is not only used for controlling the Phytoph-thora capsici Leonian and the Meloidogyne, but also widely applied to the aspects of controlling the soil-borne diseases (including the meloidogyne) in vegetables, such as hot peppers, gingers, cucumbers and the like, field crops and flowers. The pesticide composition has high application value and obvious economic and social benefits.

Description

(1) Field of invention: [0001] The present invention relates to tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione (hereinafter referred to as dazomet) and 1,3-dichloropropene (1 , 3-dichloropropene), wetting agent, dispersant, filler and other additives made of wettable powder, powder, granule composition. [0002] At the same time, the present invention relates to a method for simultaneously preventing and controlling soil-borne diseases such as Phytophthora capsici and root-knot nematodes by using the composition of cotton wool and 1,3-dichloropropene. The composition can also be widely used in the prevention and control of soil-borne diseases (including root-knot nematodes) of pepper, ginger, cucumber, tomato, strawberry, flower and the like. (2) Technical background: [0003] Dazomet, also known as Bisumi, is an environmentally friendly broad-spectrum soil fumigant with high efficiency, low toxicity and no residue, which can effectively kill nematodes, pathogenic ba...
