Embodiment 1

[0023] A kind of acaricide suspension concentrate with scopoletin and bisdemethoxycurcumin as main components, its composition and mass percentage content are 1% scopoletin, 10% bisdemethoxycurcumin, 2 % Nongru 1602, 3% sodium lauryl sulfate, 2% organic bentonite, 2% ethylene glycol, 1% n-octanol and the balance water. Prepared as follows:

[0024] 1) Mix the wetting and dispersing agent, thickener, antifreeze and water thoroughly to form a water mixing system;

[0025] 2) Add scopoletin, bisdemethoxycurcumin and defoamer to the mixed system obtained in 1), and use a high-speed shear instrument at 10,000 rpm for 2 to 10 minutes to form a uniform mixture system;

[0026] 3) Grind the mixed system obtained in 2) with a sand mill for 2 hours to obtain a compound suspension concentrate of scopoletin and bisdemethoxycurcumin.

[0027] According to the indoor toxicity test, the lethal medium concentration (LC 50 ) were 93.3 and 41.9 mg / L, respectively; 50 48.1 and 11.3 mg / L res...

Embodiment 2

[0029] A kind of acaricidal suspension concentrate with scopoletin and bisdemethoxycurcumin as main components, its composition and mass percentage content are 10% scopoletin, 5% bisdemethoxycurcumin, 3 %Nong milk 1601, 2% Morwet D-500, 2% sodium lauryl sulfate, 2% magnesium aluminum silicate, 1% xanthan gum, 2% ethylene glycol, 3% glycerin, 1% n-octanol, 3% silicone and balance water. According to the mass percentage, the product preparation is the same as in Example 1.

[0030] The obtained preparation was tested in indoor pot plants, and the control effect of 167 mg / L on Tetranychus cinnabarinus 3 days after application was 91.75%. The control agent 24% spirodiclofen suspension concentrate 100 mg / L and 73% propargite emulsifiable concentrate The control effects of 292 mg / L on Tetranychus cinnabarinus 3 days after application were 93.67% and 92.66%, respectively, and there was no significant difference ( P <0.05); the control effects of scopoletin and bisdemethoxycurcumin ...

Embodiment 3

[0032] A kind of acaricide suspension concentrate with scopoletin and bisdemethoxycurcumin as main components, its composition and mass percentage content are 5% scopoletin, 2% bisdemethoxycurcumin, 2% % Nongru 1600, 3% Morwet D-500, 2% Sodium Lauryl Sulfate, 3% Organic Bentonite, 2% Magnesium Aluminum Silicate, 1% Xanthan Gum, 2% Ethylene Glycol, 2% Propylene Glycol, 3% % glycerin, 2% silicone and balance water. According to the mass percentage, the product preparation is the same as in Example 1.

[0033] The obtained preparation was tested in the field, and the control effect of 167 mg / L on cotton field cinnabarinus 3 days after application was 71.69%. The control effects of 292 mg / L on Tetranychus cinnabarinus 3 days after application were 81.14% and 71.53%, respectively, and there was no significant difference ( P <0.05); the control effects of scopoletin and bisdemethoxycurcumin compound suspension concentrate 167 mg / L on Tetranychus cinnabarinus 7 days and 15 days aft...

Abstract

The invention relates to a scopoletin and di-bisdemethoxycurcumin complex suspending agent which is prepared from the following components by mass percent: 1-10% of scopoletin, 1-10% of di-bisdemethoxycurcumin, 2-8% of wetting dispersing agent, 2-8% of thickener, 2-8% of freeze proof agent, 1-5% of defoamer and the balance of water, wherein the scopoletin and dual-bisdemethoxycurcumin are both plant source secondary metabolite, have the characteristics of high efficiency, low toxicity, less residual and the like; and two medicines has certain differences on the modes of acting to Tetranychus cinabarinus Boisdu and target esterase, the characteristics of the two medicines are composited after complexing, and multiple action modes such as touching out, inner absorption, ovicidal action, repellent, oviposition inhibitory activity and the like are provided. Simultaneously, the suspending agent can be prepared into a suspension concentrate, which can reduce the pollution of an organic solvent on the environment, the toxicity of pesticides, the production cost and the like, and can improve the safety.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a plant-derived acaricide scopoletin and bisdemethoxycurcumin compound suspension and a preparation method thereof. Background technique [0002] There are many kinds of herbivorous mites, which are characterized by small size, fast reproduction, strong adaptability and easy to produce drug resistance. There are more than 40 species of mites that are seriously harmful, mainly spider mites and gall mites, which seriously harm citrus, Apples, cotton, vegetables, etc. At present, the varieties of acaricides commonly used in my country include pyridaben, dicofol, spirodiclofen, propargid, abamectin, etc.; the main dosage forms are emulsifiable concentrate, microemulsion, water emulsion, suspension concentrate, etc. Although chemical acaricides such as dicofol have strong acaricidal activity, they have been banned due to their serious residues. At the same time, the resistan...
