example 1

[0042] Example 1: 35% EC

[0043] Take 15.80g of pyridaben, 20.62g of Zhongbucarb, add 26.42g of cyclohexane, mix well, add 3.0g of Nongru No. 600, 3.0g of castor oil polyethylene glycol condensate, dodecylbenzenesulfonic acid Calcium 4.0g, continue to mix, then make up to 100g with xylene, and configure it into emulsifiable cream after mixing.

example 2

[0044] Example 2: 35% suspoemulsion

[0045] Take 15.80 g of pyridaben, 20.62 g of zhongbucarb, 4 g of sodium lignosulfonate, 2.5 g of sodium methylene bis-naphthalene sulfonate, 5 g of fatty alcohol polyoxyethylene ether, 3 g of castor oil polyoxyethylene ether, yellow 0.15 g of raw gum, 10 g of urea, and 3 g of octanol were added to 100 g with water, mixed evenly, put into a sand mill, and ground to a particle size of 5 μm to make a suspoemulsion.

example 3

[0046] Example 3: 30% water dispersible granules

[0047] Take 15.80 g of pyridaben, 15.80 g of zhongbucarb, 5 g of sodium methyl fatty acid amide benzene sulfonate, 5 g of sodium methylene bis-naphthalene sulfonate, 3 g of sodium carbonate, 35 g of white carbon black, lignosulfonic acid Sodium 8 g, attapulgite to 100 g. First, Zhongbucarb is adsorbed with white carbon black, and then mixed with pyridaben, sodium methyl fatty acid amide benzene sulfonate, sodium methylene bis-naphthalene sulfonate, sodium carbonate, attapulgite, and then passed through a jet mill Grinding to a particle size of 5 μm to obtain mother powder, fully mixing the mother powder with sodium lignosulfonate, granulating, drying, and sieving to obtain water-dispersible granules.

Abstract

The invention provides a compound insecticide for preventing rice planthopper. The compound insecticide comprises pyridaben and fenobucarb serving as effective components, wherein the mass ratio of the pyridaben to the fenobucarb is 4:1 to 1:128. The compound insecticide has the advantages of synergism, few dosage, wide range of prevention objects, reduction of medication cost and alleviation of environment pollution.

Description

technical field [0001] The invention belongs to the field of chemical pest control, and in particular relates to a compound insecticide for controlling rice planthoppers. Background technique [0002] Pyridaben, common name: Pyridaben, chemical name: 2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloro-3(2H)-pyridazinone, is a heterocyclic Insecticide and acaricide. Widely used in crops such as citrus, apple, cotton and tea to control various spider mites, whitefly and aphids. [0003] Zhongdingwei, common name: Fenobucarb, chemical name: o-sec-butylphenylmethyl carbamate, is a commonly used carbamate insecticide and acaricide, has osmotic transport effect on plants, and has fast insecticidal effect , has ovicidal and systemic effects, and still has good insecticidal effect under low temperature conditions. Applied to rice, cotton and other crops to control planthoppers, leafhoppers, cotton aphids, cotton bollworms and other pests. [0004] Rice planthoppers, including brown...
