The invention relates to a nematicide composition which comprises effective ingredients such as iprodione (A) and the other active ingredient (B) by mass ratio of 80:1-1:80, wherein (B) is fosthiazate, profenofos, avermectin, azadirachtin or dithiocyano-methane. In the invention, A is recomposed with B, thus having obvious synergistic effect. The composition is applied to pest control on crops such as fruit trees, cotton, wheat, paddy rape, vegetables, flowers and the like, especially for nematode control.

The invention discloses a special fertilizer for a cotton base fertilizer. The special fertilizer is prepared by silkworm excrement, wintergreen oil residue, decomposed coal, diatomite, biological bacteria, urea, diammonium hydrogen phosphate, potassium sulfate, goose feather bar, carboxymethylcellulose, 35% of sulfuric acid, lime, zinc sulfate, magnesium sulfate, manganese sulfate, nanometer iron-ore tailing powder, sweet wormwood extract, azadirachtin and wintergreen oil according to a certain weight ratio. According to the special fertilizer, amino acid is generated by feathers after acid hydrolysis, trace elements or secondary elements are cheated, and a chelate structure of the trace elements or the secondary elements is reinforced by the carboxymethylcellulose, so that the trace elements or the secondary elements can be effectively utilized and ineffective releases of the trace elements or the secondary elements can be reduced; an inorganic slow release component and a soil improvement component, namely the diatomite and the decomposed coal, are added in a formula of the special fertilizer to improve the soil and to be beneficial to the effective release of fertilizer efficiency and full absorption of the fertilizer by the crops; biological insecticide components, namely the nanometer iron-ore tailing powder, the sweet wormwood extract and the azadirachtin can effectively reduce pest and disease damage of soil, are safe and pollution-free, and do not pollute an environment or the crops; and the special fertilizer has the advantages that the formula is reasonable, the nutrition is more comprehensive and balanced, the use effect is good, the utilization rate of fertilizer efficiency can be remarkably increased, the yield and the quality of cotton are greatly improved, and the economic benefit of the cotton is increased.

An insecticide organic fertilizer composition eradicates insects such as imported fire ants (IFA). The insecticide organic fertilizer composition comprises an aqueous homogenized manure extract having an active ingredient, a surfactant, a solvent, and a fatty acid. Active ingredients include botanical insecticides which are subject to degradation after a preselected period of time upon delivery to a soil area. The botanical insecticide is selected from the group consisting of rotenone, pyrethrum, sabadilla (varatrine), neem (azadirachtin), ryania (ryanodine), and mixtures thereof, with rotenone being the preferable botanical insecticide selected. Advantageously, the combination of these components and component amounts renders the botanical insecticide's active ingredients, including rotenone, stable in the aqueous organic manure extract for a predetermined period of time. During this predetermined period of time, the insecticide organic fertilizer composition biologically interferes with IFA's pheromone distress signals. Upon application of the insecticide organic fertilizer composition to an IFA mound, the IFAs began to exhibit a state of sluggishness and gradually begin to die over time rather than relocating, effectuating effective eradication after treatment. In addition, the biotanical insecticide functions to fertilize and nourish soil near the vicinity of the mound.

The invention relates to a pesticide preparation for preventing and treating plant hoppers and other rice pests and relates to the technical field of a pesticide. A main agent of the pesticide preparation is a mixture mainly comprising the following active ingredients in percentage by weight: 0.1 to 2.0 percent of azadirachtin and 0.1 to 50.0 percent of flubendiamide. The main agent and an auxiliary agent are used to prepare a cream agent, a microemulsion, an emulsion in water or a suspending agent. The pesticide preparation is efficient for the rice pests such as the plant hoppers and the like, can prevent and treat the rice pests such as the plant hoppers in different instars, can completely kill the pests, has low pollution to the environment and low production cost and is suitable forchemical prevention of the rice pests such as the plant hoppers and the like.

The invention discloses a combination pesticide of paecilomyces fumosoroseus and azadirachtin, comprising 20 to 60 percent of host crystal and 40 to 80 percent of adjuvant according to mass percent, the host crystal is the mixture of paecilomyces fumosoroseus and azadirachtin, the mass ratio of the paecilomyces fumosoroseus and the azadirachtin is 100: 0.05 to 0.3; the adjuvant is stabilizer, addition agent and filler. By adopting the blending of agricultural chemical and biopesticide with sub-dose, the combination pesticide of the invention is superior in control effect when only one medicine is used, meets the production demands of organic foods, has no pollution and residue to environment, and is beneficial to deferring the generation of drug fastness of pests, and has good control effects on pests such as whitefly and aphis and diamondback moth, etc.

The invention discloses a mixed insecticide of paecilomyces javanicus and azadirachtin, which consists of a main agent and an adjuvant; according to the weight percent, the main agent is 20 - 60 percent, and the adjuvant is 40 - 80 percent; the main agent is the mixture of the paecilomyces javanicus and the azadirachtin, and the weight ratio of the paecilomyces javanicus and the azadirachtin is 100:0.05 - 0.25; and the adjuvant is a stabilizer, a promoter and a filler. The mixed insecticide of the invention can be processed into a wettable powder, a suspending agent or an oil agent. The mixed insecticide of the invention goes through long-term infection biology researches and indoor creature tests; by the researches and the tests, the mixed insecticide of the paecilomyces javanicus and the azadirachtin has good preventing effect on such pests as red imported fire ant, cotton leafworm, aphid, whitefly, diamondback moth, and the like, and moreover, the mixed insecticide can reduce the used amount of the azadirachtin in production practice, and can increase the quick effect of microbial insecticides and reduce chemical pesticide residues at the same time.

The invention discloses a blending preparation of a chemical pesticide and a biological pesticide and an application thereof. In the blending preparation, the chemical pesticide is dimehypo, and the biological pesticide is one or more of Azadirachtin missible oil, rotenone missible oil, bacillus thuringiensis and Jinggangmycin. The blending preparation of the invention can obviously reduce the dosage of the chemical pesticide, increases the pesticide effect of the pesticides, reduces pesticide residues, lightens environment pollution and can enhance the resistance of rice so as to reach the purposes for increasing the yield of the rice and improving the quality of the rice, and the blending preparation can be mainly used for preventing and treating Cnaphalocrocis medinalis, Chilo suppressalis, tryporyza incertulas or banded sclerotial blight of the rice.
