Embodiment 1

[0019] Example 1: Determination of the virulence of bifenazate, tolafenamide and their mixtures to the green leafhopper.

[0020] Table 1. Regression relationship of dose-response of bifenazate and tolafenamide and their mixtures to green leafhoppers.

[0021]

[0022]

[0023] figure 1 , isobologram of the synergistic effect of the mixture of bifenazate and tolafenamide on the small green leafhopper ( figure 1 The drawing refers to NY / T1155.7-2006, and the drawing data comes from Table 1).

[0024] Depend on figure 1 It is known that the ratio of bifenazate and tolafenamide is 25:1, 15:1, 7:1, 3:1, 1:1, 1:3, 1:7, 1:15, 1:25 to tea tree small The equivalent points of green leafhopper are all below the theoretical equivalent line, showing a synergistic effect; for the corresponding equivalent points of each ratio, the measured equivalent lines of bifenazate and tolafenamide are in the theoretical equivalent line Under the above, it showed a synergistic effect on the t...

Embodiment 2

[0026] Embodiment two: (40% pycnogenol bifenazate suspending agent).

[0027]

[0028] The above formula is pre-pulverized in proportion, then added to a sand mill for grinding, and mixed with high shear to prepare a 40% tolafenamide·bifenazate suspension agent.

Embodiment 3

[0029] Embodiment three: (60% pyruvic acid bifenazate water dispersible granules).

[0030]

[0031] The above materials are added together into the conical mixer and mixed evenly, and then pulverized by the jet mill. The pulverized materials are then mixed in the conical mixer. The fineness of the mixed material is 98% through a 600-mesh standard sieve and added to the kneader. Knead into plastic material, finally put this material into the extrusion granulator to extrude and granulate, after granulation, drying and sieving, 60% of tolafenamide·bifenazate water dispersible granules are obtained.

Abstract

The invention relates to a pesticide composition, the effective components of which are tolfenpyrad and bifenazate in a weight part ratio of 25:1-1:25. The tolfenpyrad and bifenazate compounded pesticide composition provided by the invention has an obviously increased effect on homoptera pests, increase efficiency obviously, improves the pest control effect, simultaneously expands the insecticidal spectrum, and also has a good treatment effect on mite, lepidoptera, coleopteran and thysanoptera pests.

Description

technical field [0001] The invention belongs to the field of agricultural pesticides, and in particular relates to a pesticide composition with tolafenamide and bifenazate as active ingredients, which is mainly suitable for preventing and controlling Homoptera pests, and simultaneously, it is suitable for preventing and treating mites, lepidoptera and coleoptera. , Hemiptera, Thysanoptera pests have a good effect on both. Background technique [0002] With the phasing out of highly toxic pesticides, new agents with high efficiency, low toxicity, safety and environmental friendliness are needed. At the same time, the long-term use of pesticides leads to the emergence of resistance to pests and weeds, and the requirements for control agents are getting higher and higher. It is necessary for pesticide R&D personnel to develop new efficient and safe drugs to meet the requirements of prevention and control. Since the creation of pesticides in my country has just started, and the...
