Oil-suspending agent disinfestation composition containing spinosyns and emamectin benzoate

The invention belongs to the field of pesticide compositions, and in particular relates to an oil-suspending agent disinfestation composition which takes spinosyns and emamectin benzoate as effective components. The oil-suspending agent disinfestations composition is mainly applied to prevention and treatment of damages caused by insects including rice cnaphalocrocis medinalis, vegetable plutella xylostella, beet armyworm and the like. The oil-suspending agent disinfestations composition is characterized in that: (1) the composition comprises effective components of the spinosyns and the emamectin benzoate, and the rest components are acceptable auxiliary components which are allowed to be used in the pesticide; and (2) the mass proportion of the spinosyns to the emamectin benzoate is 1:50-50:1, preferably 1:4-4:1; and the effective components account for 1-50 percent, preferentially 2.5-35 percent, by weight percentage in the preparation. The oil-suspending agent disinfestations composition has the advantages that the drug characteristics are complementary to each other in advantages, and one drug can prevent and treat various kinds of crop insect damages so as to be convenient for farmers to apply the drug; the drug resistance of destructive insects are retarded, which is of significance to the resistance and the comprehensive treatment to destructive insects; and the composition has the advantages of synergy, favorable permeability, strong adhesivity, evaporation resistance, storage resistance and the like, reduces the dosage and improves the disinfestation effect.

Method for improving resistance of rice plant to cnaphalocrocis medinalis by transgenic technology

InactiveCN101280289AImprove securityTo achieve the goal of high resistance to rice leaf rollerBacteriaMicrobiological testing/measurementGenetically modified riceRice plants
The invention discloses a method for improving the resistance of rice plants to rice case worms by applying the transgenic technology, and belongs to the technical field of the plant gene engineering breeding. The method comprises the following steps: Rubisco specific promoters RubS and insect-resistant genes Cry1A(b) are constructed to a pPZP201 expression plasmid carrier; the Cry1A(b) genes are integrated into a rice genome by using the method of co-transformation mediated by agrobacterium tumefaciens; the homomycin resistance genes in the self-bred progenies are rejected. The Cry1A(b) insect-resistant genes in the transgenic rice present specific high-expression, present low-expression in seeds, and have no expression in roots, thus obviously improving the resistance of the rice plants to the rice case worms, greatly reducing the pesticide application amount, reducing the production cost and improving the plant profit; simultaneously, the expression of the insect-resistant protein in rice seeds, pollen and roots is decreased, and the worry of people to the rice security is reduced.
