Problems solved by technology

However, pyrethroid insecticides can easily produce drug resistance when used alone, resulting in increased dosage and damage to the ecological environment.
At present, there are no relevant reports on the combined use of chlorantraniliprole and pyrethroids

Embodiment 1

[0035] Example 1 Indoor Toxicity Determination of Chlorantraniliprole and Pyrethroids Mixed Use on Plutella xylostella larvae

[0036] (1) Liquid preparation:

[0037] The original drug is firstly dissolved in acetone, and then diluted with an aqueous solution containing 0.15% Tween-80 to prepare a single-dose mother solution. According to the experimental mixing purpose and drug activity, 7 different proportions were designed, and 5 series of mass concentrations were set for each single agent and each group of proportioned mixtures according to the method of equal ratio.

[0038] (2) Determination method:

[0039] Leaf soaking method (proposed by the International Resistance Action Committee IRAC): a certain concentration of the drug solution to be tested, use straight tweezers to pick up fresh cabbage leaves, soak for 10 seconds, take out, shake off the remaining liquid, and dry at room temperature , spread in a 3cm petri dish pre-loaded with 1% agar (3cm thick), put 1 pie...

Embodiment 2

[0056] Example 2 Preparation of 5% chlorantraniliprole + 5% cyhalothrin suspension

[0057] The preparation of embodiment 2 suspending agent comprises the raw material of following percentage by weight:

[0058] Chlorantraniliprole 5%, cyhalothrin 5%, sodium lignosulfonate 2%, sodium dodecylbenzene sulfonate 2%, castor oil polyoxyethylene ether 3%, xanthan gum 1%, silicon Magnesium aluminum phosphate 1%, BHT 1.5%, sodium benzoate 2%, and the balance water makes up 100%.

[0059] preparation:

[0060] According to the formula amount, chlorantraniliprole, cyhalothrin, sodium lignosulfonate, sodium dodecylbenzenesulfonate, castor oil polyoxyethylene ether, xanthan gum, magnesium aluminum silicate, BHT, benzene Sodium formate and water are mixed, subjected to high-speed shearing at 10000r / min for 5min, added to a sand mill and ground until the average particle size is less than 3 microns, and made into a 5% chlorantraniliprole + 5% cyhalothrin suspension concentrate.

Embodiment 3

[0061] Example 3 Preparation of 5% chlorantraniliprole + 5% beta-cypermethrin suspension

[0062] The preparation of embodiment 3 suspending agent comprises the raw material of following percentage by weight:

[0063] Chlorantraniliprole 5%, Beta-cypermethrin 5%, Sodium Lignosulfonate 2%, Sodium Dodecyl Benzene Sulfonate 2%, Castor Oil Polyoxyethylene Ether 3%, Xanthan Gum 1%, Magnesium Aluminum Silicate 1%, BHT1.5%, sodium benzoate 2%, and the balance water makes up 100%.

Abstract

The invention belongs to the technical field of pesticide, in particular to an insecticidal composition containing butyl chlorantraniliprole and pyrethroid and application thereof. The insecticidal composition takes butyl chlorantraniliprole and pyrethroids, such as cyhalothrin, beta-cypermethrin, beta-cyfluthrin or bifenthrin, which are compounded according to certain range of weight ratio, as effective components, and further adds auxiliary components to be prepared into a finished insecticidal preparation, is applied to the control of agricultural or forest pests, has the characteristics ofbeing safe, efficient and quick-acting, is long in lasting period, prolonged in service life of pesticide and good in control effect on resistant pests, and contributes to overcoming and delaying thedrug resistance of pests. The composition obtains efficient insecticidal effect with small dosage, and solves the problems that the existing pesticide dosage is high, pesticide is frequently used, and heavy environmental load is caused.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition containing chlorantraniliprole and pyrethroids and an application thereof. Background technique [0002] The use of single-dose pesticides is often restricted by factors such as the control effect, application range, and phytotoxicity, and the control effect decreases as the resistance of pests and diseases increases. The mixing of pesticide varieties with different action mechanisms can overcome the shortcomings of the original pesticide list, and is a common method for controlling agricultural resistant pests. Through the screening of pesticide formulas, screening out reasonable formulas can effectively improve the actual control effect, reduce the dosage of pesticides, reduce costs, and delay the emergence of pest resistance. It is an important means of integrated pest management. The existing common insecticide compounding methods i...
