Embodiment 1

[0016] 1.4% Pymetrozine Thiazophos Chitin Granules

[0017] Formula: 0.1kg of pymetrozine, 1kg of thiazophos, 0.3kg of chitin, 2kg of naphthalenesulfonate formaldehyde condensate, 2kg of sodium lauryl sulfate, 2kg of starch, and kaolin to make up to 100kg.

[0018] The above components are mixed evenly, pulverized, wetted with water, fully stirred evenly, then granulated by a screw extrusion granulator, dried and sieved to obtain granules.

Embodiment 2

[0020] 1.2% Pymetrozine Thiazophos Chitin Granules

[0021] Formula: 0.1kg of pymetrozine, 1kg of thiazolin, 0.1kg of chitin, 2kg of naphthalenesulfonate formaldehyde condensate, 2kg of sodium lauryl sulfate, 2kg of starch, and kaolin to make up to 100kg.

[0022] The above components are mixed evenly, pulverized, wetted with water, fully stirred evenly, then granulated by a screw extrusion granulator, dried and sieved to obtain granules.

[0023] 3. Product application examples

[0024] The products obtained in Examples 1 and 2 were applied when bananas were planted, and the damage caused by root-knot nematodes was investigated in 45 days; the damage caused by aphids was investigated when the blank control aphids broke out. The final statistical results are shown in the table below:

Abstract

The invention relates to pesticide granules. The effective component is compounded from pymetrozine, lythidathion and chitosan in a weight ratio of 1:(10-15):(1-3). Compared with the prior art, the granules have obvious compound synergistic effect, can postpone the drug resistance of the single agent, lower the pesticide consumption and save the input cost.

Description

technical field [0001] The invention relates to a pesticide granule. Background technique [0002] Thiazophos is a kind of nematocide commonly used at present. Its insecticidal effect is fast, but its duration is short, and with the promotion of application, the resistance of nematodes to thiazophos is gradually enhanced. [0003] The application of chitin to control nematodes has a slow effect, but a long-lasting effect, and compared with other nematode control agents, the effect of increasing production is remarkable. Its insecticidal mechanism is to induce crops to produce a chitinase to decompose and absorb chitin in nematodes and egg shells, so that the nematode body wall and egg shells are dissolved, resulting in the death of nematodes and eggs. Studies have shown that chitin also has obvious contact killing effect on various aphids, and the aphids will die within 4-12 hours after contacting the pesticide. [0004] Pymetrozine is mainly used for the control of aphids...
