Embodiment 1

[0023] Example 1: Metarhizin · Dibenzuron wettable powder (the ratio of the metrhizin to the dibenzuron in grams is 1:9)

[0024] Weigh 20 grams of metarhizolin, 180 grams of diflubenzuron, 50 grams of wetting agent sodium dodecylbenzenesulfonate, 5 grams of saponin powder, 10 grams of dispersant NNO, alkylphenol polyoxyethylene phosphate 30 grams, 6 grams of tert-butylhydroquinone, and the balance is diatomaceous earth as a carrier.

[0025] Mix the diflubenzuron, the metarhizalin, the wetting agent, the dispersant, the stabilizer and the carrier uniformly in a premixing tank, and pulverize through an airflow mill to obtain a super fine powder to obtain a wettable powder insecticidal composition.

[0026] In another embodiment, the insecticidal composition is prepared by weighing 20 grams of metarhizolin, 180 grams of diflubenzuron, 25 grams of wetting agent benzocus powder, 25 grams of saponin powder, 40 grams of dispersant MF, and The amount is that kaolin and white carbo...

Embodiment 2

[0029] Example 2: Metarhizin·Diflubenzuron Suspension Concentrate (the gram ratio of the metarhizine to the diflubenzuron is 2:8).

[0030] Weigh 20 grams of metarhizolin, 80 grams of diflubenzuron, 20 grams of wetting agent sodium lauryl sulfate, 10 grams of fatty alcohol polyoxyethylene polyoxypropylene ether, 10 grams of dispersant MF, 10 grams of morwet, thickener Xanthan gum 50 grams, defoamer silicone 20 grams, thixotropic agent magnesium aluminum silicate 15 grams, stabilizer tert-butyl p-hydroxyanisole 5 grams, tertiary butyl hydroquinone 5 grams, preservative benzene 5 grams of sodium formate, 5 grams of antifreeze ethylene glycol, and the balance is deionized water.

[0031] Add the diflubenzuron, the wetting agent, the dispersant, the stabilizer, the defoamer, the thixotropic agent and deionized water into the mixing kettle in sequence, stir evenly, and After being sheared by the dispersing kettle, it enters into a sand mill for sand milling, and after sand milling u...

Embodiment 3

[0035] Example 3: Metarhizin·diflubenzuron emulsion in water (the ratio of the number of grams of metarhizine to the number of grams of dicarbenizuron is 3:7)

[0036] Take by weighing 45 grams of metarhizolin, 105 grams of diflubenzuron, 20 grams of emulsifier alkyl polyglycol ether, 30 grams of lignin sulfonate, 50 grams of co-emulsifier isobutanol, and 10 grams of thickener xanthan gum. gram, 10 grams of stabilizer tert-butyl-p-hydroxyanisole, 5 grams of antifreeze ethylene glycol, 100 grams of methanol as solvent, 200 grams of xylene, and deionized water as the balance.

[0037] Add the metarhizolin, the diflubenzuron, methanol, and xylene solvent in turn into the mixing kettle, stir evenly, and add alkyl polyglycol ether, lignosulfonate, isobutyl Alcohol, xanthan gum, tert-butyl p-hydroxyanisole, ethylene glycol, deionized water, and high shear for 1 hour to obtain a water emulsion insecticidal composition.

[0038] In another embodiment, the preparation of the insectici...

Abstract

The invention relates to an insecticidal composition with synergistic effect. The basic active components of the insecticidal composition are destruxins and diflubenzuron which are mixed according to a ratio of 1-9 g: 1-9 g. Adjuvants and excipients are added into the active components for preparation of a wettable powder, a suspending agent or an emulsion in water. The insecticidal composition can be applied to prevention and treatment of diamondback moth, prodenia litura, Lithocolletis ringoniella, grubs, wireworms, Trialeurodes vaporariorum, Liriomyza sativae, root maggots and Bradysia odoriphaga, preferably to prevention and treatment of lepidoptera insects like diamondback moth and prodenia litura on cruciferous vegetable, and has the advantages of stable efficacy, fast action, long action period, safety, environmental protection, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition containing metarhizine and diflubenzuron, a preparation method and application thereof. Background technique [0002] Metarhizin (destruxin), also known as putrefaction or destroyin, is a cyclic destruxin toxin composed of 5 amino acids and 1 hydroxy acid, and is a secondary metabolite produced by Metarhizium anisopliae during metabolism (Pedras, et al., 2002), has contact killing effect on more than 20 kinds of pests such as Lepidoptera, Homoptera, Diptera, Isoptera, Orthoptera, Coleoptera (Strasser et al., 2000; Pedras , et al., 2002; Hu Qiongbo et al., 2007), stomach toxicity (Brousseau et al., 1996) and antifeedant effect (Amiri et al., 1999; Thomsen et al., 2000); The mixed use of live fungi or commercial insecticides has a synergistic effect, such as mixing with Beauveria bassiana, Paecilomyces javanica, Metarhizium anisopliae, et...
