Embodiment 1

[0014] Example 1 10% chitosan cyantraniliprole granules

[0015] Mix 2.5g of chitosan oligosaccharide, 7.5g of cyantraniliprole, 5g of naphthalenesulfonate formaldehyde condensate, 5g of sodium alkylbenzenesulfonate, 10g of fine sand, and 30g of bentonite. The mixture is ultrafinely pulverized, granulated, dried, Sieve to make 10% chitosan cyantraniliprole granules.

Embodiment 2

[0016] Example 2 12% oligochitosan · flubendiamide water dispersible granules

[0017] Mix 3 g of chitosan oligosaccharide, 9 g of flubendiamide, 10 g of naphthalene sulfonate formaldehyde condensate, 5 g of sodium alkylbenzene sulfonate, and 100 g of white carbon black. The mixture is ultrafinely pulverized, granulated, dried, and sieved , both made of 12% oligochitosan · flubendiamide water dispersible granules.

Abstract

The invention belongs to a plant protection field, and especially relates to an insecticidal composition containing chitosan oligosaccharide, wherein the composition, beside Chitosan oligosaccharide, further contains one selected from cyantraniliprole, flubendiamide, flonicamid, chlorantraniliprole and thiamide, a mass ratio of chitosan oligosaccharide to another effective component is 0.1:1-50, and the composition can be prepared to be a suspending agent, a particulate agent, a wettable powder, a water dispersion granule, a micron emulsion or an emulsion in water. The insecticidal composition is used for controlling lepidoptera pests or homopterous insects, and has excellent control effects on diamondback moth, cabbage caterpillar, prodenia litura, rice leaf roller and apple skin worm.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to an insecticidal composition containing chitosan oligosaccharide and its application. Background technique [0002] In agricultural production, the resistance of crop diseases and insect pests to pesticide products is gradually increasing. Moreover, the diseases and insect pests of the same crop often occur at the same time. When farmers control insect pests or diseases alone, they often lose sight of one another, not only delaying work but also missing the opportunity of prevention and control, thus increasing the dosage of pesticides. Wait. Due to the single and unscientific use of medicines, the cost of farmers has increased, environmental pollution and ecological environment have been destroyed. Compounding with different structures, different mechanisms of action, and environment-friendly active ingredients, and rationally adding additives to make new agricultural composition...
