The invention discloses an optimizing process method for relieving garlic seed deterioration, belonging to the field of agriculture plant growth regulators. The optimizing process method comprises the following steps: soaking garlic seeds into a mixed solution of choline chloride with the mass volume ratio of 0.001-0.005g / L and H2O2 with the mass volume ratio of 0.1-0.5% for 12-16 hours at room temperature, drying the moisture on the surfaces of the soaked garlic seeds in air, and sowing in fields. The seed treatment method disclosed by the invention is simple and feasible, easy for farmers to master and operate and low in cost. By adopting the optimizing process method, the activity and the germination potential of the garlic seeds can be improved to a certain extent, roots can grow out rapidly after the garlic seeds are sown, the seedlings are tidy and strong after coming out, plants in the seedling stage grow exuberantly, and in the middle and later stages, the over-ground parts of the plants are strong; meanwhile, functions of disinfection and sterilization are achieved, germs carried by the seeds are reduced, and diseases such as leaf blight are also reduced; double high yields of garlic sprouts and garlic are achieved, the economic benefits of garlic planters are increased, and the optimizing process method is applicable to large-scale popularization.

The invention relates to a composite pesticide for the control of cotton Miridae which mainly comprises the following raw materials (by weight percentage): chlorophos 10-30%, acetamiprid 8-30%, emulsifying agent 10-20%, synergistic agent 5-15% and solvent 20-50%.

The invention relates to a composite pesticide containing cyhalothrin and acephate, which is mainly used for controlling cotton bollworm that is the pest of cotton. The composite pesticide comprises the components by weight percent: 1-5% of cyhalothrin and 32-39% of acephate which are added with emulsifying agent and antifreeze agent and then added with water for supplementing to 100%. After the cyhalothrin and the acephate are compounded with each other, indoor toxicity measurement proves that the synergia multiples of the product are 199.14, thus remarkably improving the effect; furthermore, the composite pesticide can greatly reduce the control times of the cotton bollworm, improves the control rate, lightens the labor intensity and reduces the environmental pollution. The form of the composite pesticide is microemulsion which takes the water as solvent, so that a great deal of organic solvent can be saved, and the safety of the product is improved. After being compounded, the pesticide not only has the reduced toxicity and production cost, but also ensures the control effect and expands the controlled objects, so as to improve the simultaneous control effect, prolong the residual effect period and greatly enhance the cost performance of the product.

The invention discloses an organic compound-inoculant insecticide-fertilizer for preventing and treating lepidoptera pests on paddy rice. The organic compound-inoculant insecticide-fertilizer comprises organic fertilizer and six biological compound inoculants which are composed of Trichoderma viride, Bacillus licheniformis, Streptomyces spirolavendulae, Bacillus subtilis, Bacillus thuringiensis and Candida. The organic compound-inoculant insecticide-fertilizer provided by the invention can improve the disease resistance and stress resistance of rice plants, prevent and treat lepidoptera pests, and prevent and control rice blast and sheath blight of paddy rice, and has an action period of about 40 days.

The invention discloses a thiamethoxam amide and monosultap containing rice seed treating agent and application thereof.The rice seed treating agent comprises active ingredients, the active ingredients are thiamethoxam amide and monosultap, and the weight ratio of thiamethoxam amide to monosultap is 1:20 to 20:1.According to the application, the seed treating agent of an effective dose is used for treating rice seeds to prevent and control lepidoptera pests.All kinds of agents are perfectly combined according to different pesticidal mechanisms of the agents and used for seed treating, a proper assistant and carrier are further adopted for assistance, a most proper ratio is found, the rice seed treating agent treats the rice seeds with a proper dosage and applied to preventing and controlling the rice lepidoptera pests, the control effect on the pests in the earlier and middle growth stages of rice is good, and the advantages of obviously reducing rice spraying preventing and control frequency, reducing environmental pollution and agricultural product residues, being long in lasting period and the like are achieved.

Novel purpose for controlling harmful cotton spider mites by utilizing amblyseius cucumeris as biological pesticide, wherein Amblyseius cucumeris is used as natural enemy for controlling and preventing cotton acarid, i.e. Cotton spider mites, including Tetrangchus urticae Koch, T. truncatus Ehara, T. cinnabarinus Boisduva and T. turkestani ugarov.

A nanosphere of abamectin used as both medicine and agricultural chemical is prepared through preparing the polylactic acid-polyglycollic acid copolymer (PLGA), mixing abemectin with PLGa, ultrasonic emulsifying, volatilizing solvent, supersonic centrifugal treating, mixing, concentrating, leaching with distilled water, and supersonic centrifugal treating, mixing, concentrating again, and freeze drying at -106- -108 deg.C. Its advantages are slow release, low poison and low cost.
