Embodiment 1

[0018] According to the content provided by the present invention, the preparation adopts the coating method, and the inventor has prepared 3% Avi imidacloprid granules, wherein the mass percentage of each component in the insecticidal granules is:

[0019]

[0020]

[0021] The inventor carried out the control test of peanut grub damage to the obtained finished product (3% Avi imidacloprid granule): the test object: the peanut variety was "Zhonghua No. 4"

[0022] Control object: Peanut grub

[0023] Drugs for testing:

[0024]

[0025] 3% Avi imidacloprid insecticidal granules control peanut grub test results:

[0026]

[0027] 3% Avi imidacloprid granule control effect of peanut grub test control effect:

[0028]

[0029] Drug efficacy calculation method:

[0030] Grub control effect (%) = (the number of grubs left in the control area - the number of grubs left in the treatment area) / the number of grubs left in the control area × 100%

Abstract

The invention provides insecticidal granules comprising the following ingredients by mass percent: 3% of a component A, 15% of a component B and 82% of a carrier, wherein the component A comprises abamectin and imidacloprid; the component B comprises an adsorbent, an adhesive and a dispersing agent. According to reasonable proportioning and synergistic effect of the ingredients, the insecticidal granules have the characteristics of good control effect, long administration optimum period, low dosage, capacities of reducing pesticide hazard and delaying disease tolerance and pesticide resistance, low investment cost, short development cycle and high economic value. The invention also discloses a method for preparing the insecticidal granules and application of the insecticidal granules to aspects of controlling peanut grub.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an insecticidal granule and its preparation method and application. Background technique [0002] Abamectin is an antibiotic insecticide fermented by microorganisms. Imidacloprid is a chemically synthesized insecticide. The control objects have certain differences. Abamectin is mainly used to control Lepidoptera pests, and imidacloprid is mainly used to control rice planthoppers, etc. pests. With the increasing resistance of pests, conventional insecticides have become less and less effective in controlling pests. [0003] The price of developing new insecticidal granules continues to rise, and the development of new drugs with high efficiency, low toxicity, and low residue has high investment costs, long research and development cycles, and low economic value. [0004] Long-term high-dose chemical pesticides are likely to cause problems such as pesticide residues, environmental pollu...
