Problems solved by technology

[0004] At present, in agricultural production, pesticides generally cannot control fungal diseases and root-knot nematodes on the roots of crops at the same time. If two different pesticides are used for different periods of control at the same time, it will not only consume a lot of labor, but also increase the cost of medication

Abstract

The invention relates to a pesticide composition for preventing and treating soybean cyst nematode. The pesticide composition comprises active components of lythidathion, trichoderma harzianum and amino-oligosaccharin. Trichoderma harzianum utilizes a mother drug with content of 30 billion CFU / g as 100% mother drug. A weight ratio of lythidathion, trichoderma harzianum to amino-oligosaccharin is 15-30: 1-3: 1-5. The active components are mixed, produce synergism, have good prevention and treatment effects on root-knot nematode and cyst nematode, can effectively prevent and treat root fungous diseases such as root rot, damping off and sheath blight, effectively prevent complex infection of root fungous diseases and nematode diseases, is safe for crops, can be used in broadcast and basal application ways, can be prepared to form granules and is convenient for use.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition for preventing and treating soybean cyst nematode disease. Background technique [0002] Root-knot nematode and cyst nematode are the two most harmful nematode diseases to agricultural production. The main damage crops are cucumber, peanut, rice, soybean, wheat, tobacco, potato, citrus, corn and so on. Nematode damage can generally reduce crop yields by 10% to 20%, and in severe cases, yields can be reduced by 70% to 90%, or even crop failure. [0003] In continuous cropping, root rot, fusarium wilt, damping-off, damping-off, and root-knot nematode and cyst nematode caused by nematodes all occur during crop planting. Soil nematodes are closely related to crop root diseases. Soil nematodes can cause plant root wounds, which are beneficial to the infection of pathogens and aggravate the diseases. Often nematodes and fungal diseases occur at the same time...
