Abstract

The invention relates to a novel nematode killing composition. The nematode killing composition comprises the following active ingredients: a compound as shown as formula 1, and fluensulfone at a weight ratio ranging from 1:40 to 30:1, further perferably 1:15 to 5:1. When the active ingredients are within the proportional range, the nematode killing composition shows an obvious synergetic effect on prevention and control of various crop root knot nematode diseases, and is particularly applicable to the prevention and control of various nematodes such as wheat root knot nematodes, cyst nematodes, citrus root knot nematodes, cucumber root knot nematodes, tomato root knot nematodes, capsicum root knot nematodes, peanut root knot nematodes and soybean cyst nematodes; the nematode killing composition has a good prevention and control effect, and is long in lasting period and worthy of popularization and application.

Description

technical field [0001] The invention relates to a nematicidal composition containing fluthiazol sulfone and a styrene-based 1,3,4-oxadiazole sulfide compound. The nematicidal composition is reasonably compounded and can effectively control various nematodes sick. Background technique [0002] Plant nematode disease is a plant disease caused by the attack and parasitism of plant parasitic nematodes. Infected plants can affect normal growth and development due to the invading nematodes absorbing nutrients in the body; the secretions of the nematodes in the metabolic process can also stimulate the cells and tissues of the host plant, resulting in plant deformities, etc., reducing the yield and quality of agricultural products. The more serious plant nematode diseases in China include root-knot nematode disease of melons, solanaceous fruits, bananas, citrus and other crops, soybean cyst nematode disease, wheat grain nematode disease, sweet potato stem nematode disease, rice ste...
