Technical Field

The invention relates to a composition of multienzyme and neonicotinoid insecticides, which comprises one or more of multienzyme and neonicotinoid insecticides as active ingredients, and belongs to the technical field of pesticides.

Background

The multienzyme is formed by high-efficiency active multienzyme composite culture, after the multienzyme composite culture is applied to soil, beneficial bacteria are massively propagated, a protective barrier is formed around the root system of crops, the harmful bacteria are inhibited by utilizing the principle of 'inhibiting bacteria with bacteria', substances secreted by the beneficial bacteria in the propagation process can inhibit and kill the harmful bacteria, meanwhile, ineffective nutrients in the soil are activated, and the nutrient imbalance and nutrient deficiency symptoms disappear. The multienzyme can effectively activate the in vivo anti-stress immune system of the crops and enhance the comprehensive resistance (drought resistance, cold resistance, heat resistance, alkali resistance, waterlogging and diseases) of the crops; inducing crops to generate disease-resistant factors and improving the bactericidal capacity of the crops; protecting crop cell membrane, enhancing cell activity, and improving photosynthetic efficiency; supplementing trace elements required by plant growth; pesticide residue is effectively degraded, and quality is improved; effectively relieve the phytotoxicity and fertilizer damage of the herbicide.

Neonicotinoids act primarily on the nicotinic acetylcholine receptors (nAChRs) on the postsynaptic membranes of insects. Acetylcholine is an endogenous agonist of the insect nervous system and is capable of stimulating neurotransmitters. The nicotine with insecticidal activity has a nitrogen atom protonation under physiological conditions, ionized nicotine is not easy to penetrate ion barriers around the central nervous system, and the neonicotine insecticide can overcome the binding of the ion barriers and target sites due to the hydrophobicity of the nicotine insecticide. Compared with nicotine, neonicotinoid insecticides have a stronger affinity with the site of action.

The neonicotinoid insecticide is deeply loved by the broad masses of users due to the characteristics of unique and novel action mode, low toxicity, high efficiency, broad spectrum and the like and good prevention and treatment effect.

Clothianidin is an insecticide in neonicotinoids, is a novel efficient, safe and high-selectivity insecticide, has similar action to nicotinic acetylcholine receptors, and has contact poisoning, stomach toxicity and systemic activity. The pesticide is mainly used for preventing and controlling hemiptera, coleopteran, dipteran and certain lepidopteran pests such as aphids, leafhoppers, thrips, plant hoppers and the like on rice, vegetables, fruit trees and other crops, has the advantages of high efficiency, broad spectrum, low dosage, low toxicity, long efficacy duration, no phytotoxicity to the crops, safe use, no cross resistance with conventional pesticides and the like, has excellent systemic and osmotic effects, and is another variety for replacing high-toxicity organophosphorus pesticides.

Thiamethoxam is a neonicotinoid high-efficiency low-toxicity insecticide with a brand-new structure, has stomach toxicity, contact killing and systemic activity on pests, and is used for leaf surface spraying and soil root irrigation treatment. After the pesticide is applied, the pesticide is absorbed quickly and is conducted to each part of the plant, and the pesticide has good control effect on piercing-sucking pests such as aphids, plant hoppers, leafhoppers, whiteflies and the like.

Dinotefuran has the characteristics of strong contact toxicity, stomach toxicity and root systemic property, high quick effect, long lasting period of 3-4 weeks (theoretical lasting 43 days), wide insecticidal spectrum and the like, has excellent control effect on pests with sucking mouth parts, and shows high insecticidal activity at very low dosage. Mainly used for preventing and controlling aphids, leafhoppers, plant hoppers, thrips, whiteflies and resistant strains thereof on various crops such as wheat, rice, cotton, vegetables, fruit trees, tobacco leaves and the like, has high efficiency on coleoptera, diptera, lepidoptera, diptera, beetle and total-ptera pests, and has high efficiency on sanitary pests such as cockroaches, termites, houseflies and the like

The neonicotinoid insecticide can be used for foliar spraying and soil treatment. Through research, the synergistic effect is obvious after the combination of multienzyme and one or more of neonicotinoid insecticides, and the dosage is reduced.
