Problems solved by technology

[0009] Above-mentioned prior art is all used for preventing and killing cotton bollworm, although two-spotted armyworm is the Lepidoptera Noctuidae pest equally, because the generation of two-spotted armyworm and cotton bollworm's harmful characteristics have bigger Therefore, it is necessary to develop corresponding pesticide compound preparations and application technologies for the two-spotted armyworm

Embodiment 1

[0035] Example 1 20% emulsifiable concentrate

[0036] First take the following raw materials by weight:

[0037]

[0038]

[0039] Then, add phoxim, fenvalerate and methanol into a container equipped with a thermometer and agitator, heat to 40°C, stir for 60 minutes, then gradually add emulsifier 2201 and stir, add toluene after uniformity, stir After 60 minutes, when the temperature dropped to 30°C, the emulsion changed from white to a transparent substance solution, and became 20% emulsifiable oil after filtration.

Embodiment 2

[0040] Example 2 30% emulsifiable concentrate

[0041] First take the following raw materials by weight:

[0042]

[0043] Then add phoxim, fenvalerate, and co-solvent methanol into the container, heat to 30°C, stir for 30 minutes, then add emulsifier 0201-B and stir, then add toluene, stir for 90 minutes, then it becomes transparent The substance solution was cooled to 15°C, and after filtration, the emulsifiable concentrate containing phoxim and fenvalerate was obtained.

Embodiment 3

[0044] Embodiment 3 40% emulsifiable concentrate

[0045] First take the following raw materials by weight:

[0046]

[0047] Add phoxim, fenvalerate, and co-solvent ethanol into the container, heat to 50°C, stir for 90 minutes, then add emulsifier and stir, then add toluene, stir for 60 minutes, then it becomes a transparent substance solution, Cool down to 30°C and filter to form an emulsifiable concentrate containing phoxim and fenvalerate.

Abstract

The invention relates to missible oil containing phoxim and fenvalerate and its preparation method and use. The missible oil containing phoxim and fenvalerate comprises active ingredients of 10.0 to 40.0 parts by weight of phoxim and 4.0 to 20.0 parts by weight of fenvalerate. The missible oil containing phoxim and fenvalerate realizes combination of phoxim and fenvalerate so that respective advantages of phoxim and fenvalerate can be fully performed and thus the missible oil containing phoxim and fenvalerate can be used for control of Athetis lepigone Moschler. Through the combination of phoxim and fenvalerate, obvious synergistic effects are obtained; control effects are improved; pesticide resistance production is delayed; and quick-action and effect persistence are good. Therefore, the missible oil containing phoxim and fenvalerate is superior to the prior art.

Description

technical field [0001] The invention relates to the field of pesticides and insecticides, in particular to emulsifiable concentrate containing phoxim and fenvalerate, as well as its preparation method and application. Background technique [0002] Athetis lepigone Moschler belongs to Lepidoptera Noctuidae. Since it was first discovered in Hebei Province in 2005 to damage summer maize seedlings, the area where the damage occurred has gradually expanded, and the degree of damage has become more and more severe. , has seriously threatened the safe production of summer maize in northern my country. The larvae of this insect mainly damage the root base of host crops and bite the young tissues of the root base; or damage the stem base and rot the stem, resulting in the death of the seedlings, especially for corn seedlings at the 3-5 leaf stage, which often cause replanting or destruction. . Since Spodoptera spp. is a new explosive pest, there is an urgent need for high-efficiency...
