The active components of the composition are chromafenozide and bistrifluron in weight ratio of 1: (5-7), preferably 1:6. The composition is composed of effective components in different mechanisms of action, the acting sites are increased so as to facilitate the overcoming and delaying of the production of pest resistance to insecticide, and the insecticidal spectrum is broadened; the pesticide effect is greatly improved, the lasting time is long, the field dosage of the active component are reduced, the production cost and the use cost are reduced, and the pesticide residue and environment pollution are reduced.

The invention belongs to the technical field of agricultural pesticides and particularly relates to a clothianidin and tebufenozide compound insecticidal composition. The clothianidin and tebufenozide compound insecticidal composition has the effective components of clothianidin and tebufenozide of which the weight ratio is 1:(4 to 8) and preferably 1:(5 to 7). The clothianidin and tebufenozide compound insecticidal composition consists of the effective components with different function mechanisms, the acting sites are increased to be conductive to overcoming and delaying production of pest drug resistance, and the insecticidal spectrum is broadened; the drug effect is greatly improved, the prevention time is long, field consumption of the effective components is reduced, the production and use costs are lowered, and pesticide residues and environmental pollution are reduced.

The invention belongs to the field of pesticide, in particular to an insecticidal composition for preventing and treating agricultural pests and a purpose of the insecticidal composition. The insecticidal composition has active ingredients such as lufenuron and propargite, wherein the mass ratio of lufenuron to propargite as the active ingredients is 1:(6-20), and is preferably 1:(10-16). Besides the lufenuron and the propargite as the active ingredients, the insecticidal composition also comprises agricultural preparation auxiliary ingredients so that the insecticidal composition is made into missible oil, microemulsion or water emulsion. The insecticidal composition is mainly used for preventing and treating lepidopteran pests and mite pests. The insecticidal composition prepared by the invention has the advantages that the synergia effect is obvious, and the medicine effect is greatly improved; the effect taking time is long, the field consumption of active ingredients is reduced, the production and use cost is reduced, and the environment pollution is reduced; and the pest drug resistance generation is favorably overcome and delayed, and the insecticidal composition belongs to an important measure for preventing and treating field pests.

The invention belongs to the technical field of agricultural insecticides, and particularly relates to a Dinotefuran / Bifenazate compound insecticidal composition. The effective ingredients are Dinotefuran and Bifenazate in a weight ratio of 2:1-1:3, preferably 1:2. The Dinotefuran / Bifenazate compound insecticidal composition is composed of the effective ingredients with different action mechanisms, so that the action sites are increased, thereby being beneficial to overcoming and postponing the generation of insecticide resistance of insects, and widening the insecticidal spectrum; and the invention greatly enhances the insecticidal effect, has the advantages of long preventive effect time and lower consumption of effective ingredients in the field, lowers the production and use cost, and reduces the insecticide residue and environmental pollution.

The invention belongs to the technical field of agricultural insecticide and particularly relates to a thiamethoxam and clothianidin compounded insecticidal composition. Thiamethoxam and clothianidin serve as effective ingredients of the insecticidal composition and are in the weight ratio of 1: (0.5 to 4), preferably 1: (1 to 3). The insecticidal composition consists of the effective ingredients of different action mechanisms, so that the action sites are increased, the overcome and delay to the generation of insect pest pesticide resistance are favored, and the insecticidal spectrum is broadened; and the pesticide effect is greatly improved, the control effect time is long, the field dosage of the effective ingredients is reduced, the production and use costs are reduced, and the insecticide residue and environmental pollution are reduced.

The invention relates to the technical field of pesticides, more specifically, the invention relates to a pesticide composition and a preparation method thereof. In parts by weight, at least the following components are included: 90-100 parts of mineral oil, 1-8 parts of multi-carbon chain organic matter, 0.1-1 part of dispersant, and 0.1-1 part of auxiliary agent. The present invention adopts mineral oil, multi-carbon chain organic matter, dispersant, and auxiliary agent to jointly prepare the pesticide composition, and the mineral oil, multi-carbon chain organic matter, dispersant, and auxiliary agent have a good synergistic effect, and the prepared agricultural chemical composition It can prevent and control a variety of pests, and has high activity on spider mites, panonychia, aphids, whitefly, whitefly, short beard mite, rust mite, etc. on vegetables, fruit trees, cotton, rice and other crops. Excellent, long-term control effect, and greatly reduce the dosage. In addition, the pesticide composition of the present invention achieves the effect of controlling pests through physical action, basically has no residue on crops, is harmless to human body and environment, and pests will not develop drug resistance.

The invention provides a fungal agent prepared by using African Trichoderma harzianum Ta97 and its application in preventing and treating heavy cropping diseases. 7 ~1×10 8 Cfu / mL seed solution was inoculated into solid fermentation medium, stirred evenly, cultured for 5-8 days at a constant temperature of 25-28°C, 12 hours of light and 12 hours of darkness, air-dried and passed through 60 and 100 mesh sieves successively, and taken Mix the under-sieve part with diatomaceous earth according to the weight ratio of 5 to 7:1 to obtain Trichoderma conidia powder; mix the Trichoderma conidia powder with an auxiliary agent to obtain a bacterial agent; use the bacterial agent to prevent heavy cropping Disease application. The control effect of the bacterial agent on the repeated cropping disease is more than 80%, which shows that the bacterial agent has a good control effect on the repeated cropping disease, and is beneficial to continuous cropping in the field.

The invention belongs to the technical field of agricultural insecticides and in particular relates to a dihalopyrazole amide and chlorfenapyr compound insecticidal composition. The active ingredients of the insecticidal composition are dihalopyrazole amide and chlorfenapyr in a weight ratio of 1 to (2-4), preferably 1 to 3. The insecticidal composition has the beneficial effects that the insecticidal composition is formed by the active ingredients with different mechanisms of action and the action sites are increased, so that the insecticidal composition is conducive to overcoming and delaying the drug resistance of insect pests and widening the insecticidal spectrums; the efficacy is substantially improved, the control effect duration is long, and the use quantities of the active ingredients in the fields are reduced, thus reducing the production and use costs and reducing the pesticide residues and environmental pollution.
