Embodiment 1

[0027] Embodiment 1 Composite synergistic insecticide is to indoor toxicity determination of cotton bollworm

[0028] On the basis of the preliminary test, accurately weigh a certain amount of A, B and the original medicines with different ratios of A and B, and set A and B respectively according to the mass ratio of the active ingredients: when the mass percentage of the active ingredients accounts for When the total content is 5%, the mass ratio of emamectin benzoate to imidacloprid is 0.5:4.5~1.5:3.5; when the mass percentage of active ingredients accounts for 9% of the total content, the mass ratio of emamectin benzoate to imidacloprid is 0.5 : 8.5~1.5: 7.5. Dissolve with acetone or other suitable organic solvents, and add Triton-X100 with a final concentration of 100 mg / L to prepare a mother solution. The test was determined by the leaf-dipping inoculation method.

Abstract

The invention provides complex synergism insecticide and application thereof. Emamectin benzoate and imidacloprid serve as effective constituents of the insecticide. When the mass percentage content of the effective constituents accounts for 5% of the total content, the mass ratio of emamectin benzoate to imidacloprid is between 0.5 to 4.5 and 1.5 to 3.5; when the mass percentage content of the effective constituents accounts for 9% of the total content, the mass ratio of emamectin benzoate to imidacloprid is between 0.5 to 8.5 and 1.5 to 7.5. By means of indoor toxicity measurement, the effects of emamectin benzoate and imidacloprid on cotton field insects are analyzed after emamectin benzoate and imidacloprid are used independently and used in a compound mode, the effects of different agents are compared, the optimal ratio of emamectin benzoate and imidacloprid is determined and used for production, and the aims of expanding insecticidal spectrums, improving control effects, reducing environment pollution and delaying pest resistance to insecticide are achieved.

Description

technical field [0001] The invention relates to the field of prevention and control of agricultural diseases and insect pests, in particular to a compounded and synergistic insecticide and its application. Background technique [0002] Cotton (Gossypium hirstum L.) is an important economic crop in the world and occupies a very important position in the national economy of our country. However, cotton is also one of the crops with many types of pests and heavy damage from pests. There are more than 300 known cotton pests in my country, of which more than 30 are the main ones, which cause a 15% to 20% reduction in cotton production all year round. In the 1990s, cotton bollworm (Helicoverpa armigera H.) broke out in the cotton areas of the Yellow River Basin and the Yangtze River Basin in my country, and the annual economic loss reached tens of billions of dollars. The outbreak of cotton bollworm has brought opportunities for the large-scale application of transgenic insect-re...
