Abstract

The invention relates to a pesticide composition for controlling nematode, and the pesticide composition can effectively control the nematodes. The active ingredients of the pesticide composition comprise emamectin benzoate and fluopyram, and the weight ratio of the emamectin benzoate and the fluopyram is (1 to 20) to (20 to 1). The pesticide composition can be prepared into missible oil, suspending agent, wettable powder, water dispersible granule, emulsion in water, microemulsion, granula, microcapsules, microcapsule suspension-suspending agent and the like according to a method known by those skilled in the field. The pesticide composition provided by the invention has an obvious synergistic effect on the nematodes, the dosage is reduced, the cost is lowered, and the persistence is prolonged, and the pesticide composition is efficient, harmfulless and low residual.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition for controlling nematodes. Background technique [0002] Root-knot nematode is one of the main diseases of crops such as Solanaceae and Cucurbitaceae. It occurs in both the north and the south of my country. Especially in facility agriculture, crops that are easily infested by nematodes are planted all year round, resulting in the widespread occurrence of root-knot nematode and causing serious economic loss. At present, there are few pesticides registered for the control of plant root-knot nematodes in my country. Years of continuous use have produced resistance, poor efficacy, and large application volumes, resulting in excessive pesticide residues, environmental pollution, and high application costs. Therefore, there is an urgent need to develop a drug that is convenient to use and highly effective against nematodes in agricultural production. [000...
