Problems solved by technology

The mechanism of action of thiazole phosphine is mainly to avoid nematodes from damage, and the ability to kill nematodes is relatively weak. However, the market for nematicides is huge in the future, and thiazolyl phosphine cannot meet the demand
In addition, the contact activity of abamectin to root-knot nematodes is relatively strong, but the shortcoming is that the persistence period is too short

Embodiment 1

[0047] Weigh 5% fluopyram, 10% thiamethoxam, 8% sodium alkylnaphthalenesulfonate, 5% sodium naphthalenesulfonate, 3% dextrin, and add talcum powder to 100% by weight. The above raw materials are uniformly mixed in a mixing tank, extruded, granulated, dried, and sieved to obtain 15% fluopyram·thiamethoxam granules.

Embodiment 2

[0049] Weigh 5% fluopyram, 10% imidacloprid, 5% sodium lignosulfonate, 3% sodium alkylsulfonate, 5% polyvinylpyrrolidone, and add kaolin to 100% by weight. The above raw materials are uniformly mixed in a mixing tank, extruded, granulated, dried, and screened to obtain 15% fluopyram imidacloprid granules.

Embodiment 3

[0051] Weigh 5% fluopyram, 10% dinotefuran, 4% sodium polycarboxylate, 4% sodium alkyl sulfate, 4% polyvinyl alcohol, and add calcium carbonate to 100% by weight. The above raw materials are uniformly mixed in a mixing tank, extruded, granulated, dried, and sieved to obtain 15% fluopyram · dinotefuran granules.

Abstract

The invention discloses a nematicidal composition containing fluopyram and a nicotine insecticide and an application thereof. The nematicidal composition is composed of a first active component, namely the fluopyram, a second active component, namely one of the nicotine insecticides thiamethoxam, imidacloprid, dinotefuran and sulfoxaflor, and an auxiliary agent, wherein the weight ratio of the first active component to the second active component is (1:20)-(20:1); the content sum of the first active component and the second active component is 1%-60% of the total weight of the composition. The composition can be made into granules, water dispersible granules, missible oil, an emulsion in water and a suspending agent which are agriculturally allowed. The components are reasonably compounded, the effect on vegetable nematode is good, and the nematicidal effect is not simply superposed by the activities of all the components. Compared with a conventional single preparation, the nematicidal composition has a remarkable nematicidal effect and a remarkable synergistic effect, has the dosage reduced, and has good safety to crops.

Description

technical field [0001] The invention relates to a nematocidal composition, which is composed of a first active ingredient fluopyram, a second active ingredient nicotinic insecticide and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Nematodes belong to the nematode class Nematodes. They are small in size and can only be observed with a microscope. There are about 3,000 kinds of nematodes that are harmful to plants and are common in China. Most of them live in the soil, and some also parasitize in plants. Nematodes spread through soil or seeds and can damage the root system of plants; directly eating plants can greatly reduce the absorption of nutrients and water by plants, and nematodes eating plants cause wounds and facilitate the invasion of plant pathogens. Fungal and bacterial diseases caused by microorganisms, such as fusarium wilt, damping-off, root rot, soft rot and other root diseases. [0003] At presen...
