Description
Technical Field
The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition for preventing and controlling taro field red spiders.
Background
Taro, also known as taro, taro or taro, is a perennial tuber plant of the genus arisaema, and is an important cash crop. Taro is often damaged by diseases and insects in the whole growth process, so that the quality and the yield of the taro are reduced, and certain economic loss is caused for growers. The taro field main insect pests include prodenia litura, aphid, red spider and the like. Wherein, the red spider is taro Tian Changfa pest, which is in the form of ovum or fertilized female mite in the crack of plant, plant residue and shallow soil layer around root. In the next year, the temperature rises, and overwintering fertilized female mites start to harm the plants which just sprout. The red spiders firstly harm the two sides of the main vein on the back of the leaf to pierce and suck juice, spit silk, net and lay eggs, inhibit photosynthesis of crops, reduce accumulation of nutrients, cause the leaf to turn yellow and lose green, and influence the yield and quality of the crops.
At present, chemical control is still one of the main means for controlling taro field red spiders in production, but due to the fact that a grower uses a single chemical agent for a long time and the like, unreasonable medication causes resistance to a plurality of acaricides to different degrees, and the control effect of the agent is reduced to different degrees. Although the application dosage of the medicament can be increased to a certain extent, the medicament resistance is further increased, and the prevention cost and the pesticide residue are increased. Therefore, research and development of novel agents is necessary.
Cyanotebufenpyrad is used as a lead compound by Shenyang neutralization pesticide chemical industry research and development limited company, and the compound ethaboxam with higher acaricidal activity is discovered by carrying out structural modification on a pyrazole ring and a hydroxyl part in the structure of the compound ethaboxam. The etoxazole is a brand new compound, has no cross resistance with the existing acaricide, has outstanding quick-acting property, can reach extremely high death rate in 1-3 days, has excellent effect on four insect states of red spiders, is safe to crops, and is environment-friendly. However, as the ethaboxam is a chemical agent, although the ethaboxam has better acaricidal activity at present, if the ethaboxam is singly used for a long time, the red spider can slowly accumulate the drug resistance to the ethaboxam, so that the acaricidal activity of the ethaboxam is gradually reduced.
The compounding of different pesticide effective components is a common means for developing new pesticide products and preventing and treating disease and insect pests at present. The formulated medicament will exhibit: the three modes of action of antagonism, additive action and synergistic action, compared with single medicament, the compound medicament with synergistic action can effectively improve the control effect on plant diseases and insect pests and delay the generation of drug resistance of plant diseases and insect pests. The inventor finds that after the ethionazole and the osthole, matrine or cycloxaprid are compounded, the invention has good synergistic effect on taro field red spiders, and can provide support for developing novel medicaments based on the synergistic effect.
