Embodiment 1

[0017] Example 1: Composition and preparation method of 40.1% flupyrfurone·cyclafenozide aqueous emulsion:

[0018] The mass percentage (%) of each active ingredient of the main agent of this example is: flurpirfurone 40.0, fenfenozide 0.1;

[0019] The mass percentage (%) of each component of the auxiliary agent is: solvent: ethylene glycol 10.0, dimethylformamide 10.0; emulsifier: 2,4,6-tris(1-phenylethyl)phenol poly(20) ethylene glycol Alcohol Phosphate Monoester 6.0, Polyoxyethylene Phenylphenol Ether 8.0; Dispersant: Sodium Lignosulfonate 5.0; Antifreeze Agent: Glycerol 2.0, Polyethylene Glycol 3.0; Stabilizer: Pyrogallic Acid 4.0, Sudan Black 1.0; Water 10.9.

[0020] After mixing the raw materials with the above mass ratio, the aqueous emulsion is processed into an aqueous emulsion.

Embodiment 2

[0023] The mass percentages (%) of each component of the adjuvant are: solvent: ethylene glycol 8.0, polyethylene glycol 6.0; emulsifier: ethoxylated alkyl ether 5.0, ethylene oxide-fatty acid primary amine condensate 5.0; dispersant: Sodium lignosulfonate 2.0; antifreeze agent: hexanediol 3.0, glycerol 1.0; stabilizer: butyl glycidyl ether 3.0, polyethylene glycol diglycidyl ether 2.0; water 25.0.

[0024] After mixing the raw materials with the above mass ratio, the aqueous emulsion is processed into an aqueous emulsion.

Embodiment 3

[0025] Example 3: Composition and preparation method of 20.0% flupyrfurone·cyclafenozide aqueous emulsion:

[0026] The mass percent (%) of each active ingredient in the main agent of this example is: flurpirfurone 10.0, fenfenozide 10.0;

[0027] The mass percentages (%) of each component of the adjuvant are: solvent: polyethylene glycol 5.0, N-long chain alkyl pyrrolidone 5.0; emulsifier: alkyl polyethylene glycol ether 6.0, 2,4,6-tri(1 -Phenylethyl)phenol poly(20)ethylene glycol phosphate monoester 5.0; dispersant: sodium lignosulfonate 1.0, sodium methylene bis-naphthalene sulfonate 1.5; antifreeze agent: hexanediol 1.0, glycerin 1.0; stabilizer: pyrogallic acid 1.0, p-nitrobenzoic acid 1.0; water 52.5.

[0028] After mixing the raw materials with the above mass ratio, the aqueous emulsion is processed into an aqueous emulsion.

Abstract

The invention relates to an unmanned plant protection machine spraying preparation for preventing and treating rice insects and a preparation method thereof and belongs to the technical field of plantprotection. The unmanned plant protection machine spraying preparation comprises flupyradifurone, chromafenozide and auxiliary agents, wherein the flupyradifurone accounts for 0.1-40.0% of the totalweight of the pesticide; the chromafenozide accounts for 0.1-40.0% of the total weight of the pesticide; and the balance is the auxiliary agents. The preparation method comprises the following steps:mixing the component raw materials according to the weight percentages, and preparing an emulsion in water by using a conventional emulsion in water processing method. By adopting the unmanned plant protection machine spraying preparation, the defects that serious drug resistance is resulted and prevention and treatment effects are poor and poor as single chromafenozide chemicals are adopted to prevent and treat rice insects for a long time are overcome, the preparation is applicable to spraying application through an unmanned plant protection machine, rice leaf folders can be prevented and treated, and the medicine spraying efficiency is improved.

Description

technical field [0001] The invention relates to a formulation suitable for spray application by an unmanned plant protection machine and a preparation method thereof, belonging to the technical field of plant protection. Background technique [0002] Rice leaf roller (Cnaphalocrocis medinalis Guenee) mainly damages rice, sometimes wheat, sugarcane, millet and grass weeds. The adult bracts of rice leaves are rolled vertically by the larvae, and the larvae hide in it to feed on the mesophyll, leaving only the epidermis, forming white streaks, resulting in a decrease in the thousand-grain weight of rice and an increase in grains, resulting in reduced yield. Since the 1990s, due to the adjustment of the planting structure and the reform of the farming system, the damage of the rice leaf roller has increased year by year in my country's rice fields, and the long-term irrational use of chemical pesticides has led to the enhancement of the resistance of the leaf roller, causing man...
