Nematoid-killing composition containing abamectin and paecilomyces lilacinus

Abstract

The invention relates to a nematoid-killing composition containing abamectin and paecilomyces lilacinus, which is characterized by comprising abamectin and paecilomyces lilacinus; 100g of nematoid-killing composition is prepared by the following components of 0.1-5g of abamectin, 0.1-1 billion live spores / g of paecilomyces lilacinus, 1-10g of stabilizing agent, 1-90g of solvent and 10-90g of assistant, wherein the assistant is any one or the combination of any two of attapulgite, kaoline, sepiolite, light calcium and kieselguhr and is prepared into a granular formulation or suspending agent or wettable powder; the stabilizing agent is any one or the combination of any two of castor oil, soybean oil, epoxidized soybean oil, propylene glycol, methyl oleate, ethylene glycol, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA); and the solvent is any one of dimethylbenzene, trimethylbenzene and dimethylformamide. The nematoid-killing composition is used for controlling the knot nematode and has better control effect on the knot nematode.

Description

technical field [0001] The invention relates to a pesticide composition for preventing agricultural root-knot nematodes. Background technique [0002] Root-knot nematodes mainly damage the roots of various vegetables, showing more lateral roots and fibrous roots than normal, and forming spherical or conical white nodules of various sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plant. The nematodes currently known to damage vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Nematodes have a wide range of hosts and often damage more than 30 kinds of vegetables such as melons, solanaceous fruits, beans, radishes, carrots, lettuce, and cabbage, and can also spread some fungal and bacterial diseases.

AI Technical Summary

Problems solved by technology

[0005] Due to long-term, single use or abuse of pesticides in agricultural production, pests have developed resistance to pesticides, and even developed cross-resistance and multi-resistance, making many pesticide varieties useless

However, the research and development cycle of new pesticides is long, and they are often not available, which is a major obstacle to agricultural production.
