Problems solved by technology

Moreover, the pests at the seedling stage are mainly aphids and thrips, which mainly rely on chemical control. With the widespread use of insecticides and unreasonable field use, cotton aphids are resistant to organochlorines, organophosphorus, pyrethroids, Insecticides such as carbamates and some nicotines are gradually developing resistance

preparation example Construction

[0045] The preparation method of a combined pest control drug spray provided by the present invention comprises: diluting the combined pest control drug provided in the embodiment of the present invention. Specifically: after dilution so that the concentration of the botanical pesticide is a (0.375 ~ 0.5) + k (0.375 ~ 0.75) + b (2.4 ~ 3.6) + c (4.48 ~ 8.96) g / 30kg, the concentration of the first fungicide It is d(5~15)+e(1.5~3)g / 30kg, and the concentration of chlorothialine is (0.5~1)g / 30kg. When the component concentration of the pest control combination drug spray is within the range of the above-mentioned dilution multiples, it can effectively control thrips and aphids, and has no influence on the environment and natural enemies.

[0046] Preferably, the medicament raw materials of the insect control combination drug spray include: 0.5wt% matrine aqueous solution, 0.5wt% veratrine soluble agent, 6wt% rotenone microemulsion, 22.4wt% spirotetramat suspension, 50wt% Trifloxys...

Embodiment 1

[0061] The embodiment of the present invention provides a method for preventing and controlling pests and diseases at the seedling stage of cotton fields with a combination drug spray for controlling insects.

[0062] Combination drug spray for controlling pests is to adopt commercially available mass concentration as 0.5% veratrine soluble 75g, 50% trifloxystrobin suspending agent 20g and 10% chlorothialine wettable powder 7.5g to mix and then add 30kg water to dilute to obtain, above-mentioned The dilution ratios of the components were 400, 1500 and 4000, respectively. The amount of this spray is the spraying amount of one mu of cotton field.

[0063] The initial spray is obtained by mixing 200g of foliar fertilizer N-boost, 20g of trifloxystrobin suspending agent with a mass concentration of 50%, and 6.67g of brassinolide soluble agent with a mass concentration of 0.01%, and then diluting with 20kg of water . The dilution factors of the above components are 100, 1000 and ...

Embodiment 2

[0068] The embodiment of the present invention provides a method for preventing and controlling pests and diseases at the seedling stage of cotton fields with a combination drug spray for controlling insects.

[0069] The pest control combination drug spray is obtained by mixing 150 g of commercially available mass concentration of 0.5% veratrine soluble solvent, 30 g of 50% trifloxystrobin suspension concentrate and 10 g of 10% chlorothialine wettable powder, and then adding 30 kg of water to dilute. The dilution multiples of the above-mentioned components are 200, 1000, and 3000 respectively, and the amount of this spray is the spray amount for one mu of cotton field.

[0070] The initial spray is obtained by mixing 160g of foliar fertilizer N-boost, 13.34g of trifloxystrobin suspension concentrate with a mass concentration of 50%, and 20g of brassinolide soluble agent with a mass concentration of 0.01%, and then diluting with 20kg of water . The dilution factors of the abo...

Abstract

The invention relates to the technical field of agriculture, and discloses an insect control combined medicine, a spray, a preparation method and application thereof, and a method for controlling diseases and insect pests in cotton fields at seedling stage. The medicine comprises plant-derived pesticides, a first bactericide and imidaclothiz; the botanical pesticides comprise at least one of veratrine, matrine, rotenone and spirotetramat; the first bactericide comprises at least one of trifloxystrobin and pyraoxystrobin. The spray is obtained by diluting the insect control combined medicine. The preparation method of the insect control combined medicine spray comprises diluting the insect control combined medicine. The method for preventing and controlling diseases and insect pests in cotton field seedling stage comprises the steps of using the insect control combined medicine spray to control insects. The medicament and the method have good effects of preventing diseases and treatinginsects. Preferably, the pest control method further comprises: planting cotton in cotton fields near wheat fields; spraying an initial spray at the stage of two leaves of cotton emergence. The combination of the three pest control methods can achieve more obvious pest control and disease prevention effects.

Description

Technical field [0001] The present invention relates to the field of agricultural technology, specifically to pest control combination drugs, sprays and preparation methods and applications thereof, as well as methods for preventing and controlling seedling diseases and insect pests in cotton fields. Background technique [0002] Cotton is one of the most important crops in my country. It is the main raw material for the prevention and control industry and has high economic value. The quality of cotton in the seedling stage is related to the future growth trend of the plant as well as the yield and quality of cotton. In the seedling stage, cotton is a vegetative growth stage dominated by long roots, long stems, and long leaves. In the seedling stage, the growth of above-ground stems and leaves is slow. . Generally, the temperature in the seedling stage is low and unstable, and the seedlings have poor stress resistance. The growth of cotton seedlings is weak, which can easil...
