Abstract

The invention relates to a pesticide, and in particular relates to abamectin. The abamectin anti-photolysis anti-oxidation suspending agent comprises the following components in percentage by weight: 5 to 30 percent of abamectin, 0.1 to 0.2 percent of BHT (butylated hydroxytoluene), 0.1 to 0.3 percent of bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate, 0.1 to 0.2 percent of 2-(2'-hydroxyl-3'-tert-butyl-5'-methyl phenyl)-5-chlorobenzotriazole, 12 to 15 percent of an auxiliary agent, and water which is supplemented to 100 percent, wherein the auxiliary agent is prepared from the following component sin percentage by weight: 0.7 to 2 percent of NNO (naphthyl sulfonate formaldehyde condensate), 4 to 5 percent of Ning emulsion 34#, 1 to 3 percent of Nong emulsion 500#, 1 to 2 percent of aluminium-magnesium silicate, 0.1 percent of sodium benzoate, 5 percent of glycol, and 0.2 percent of defoaming agent. According to the suspending agent, the defect that abamectin is oxidized and photolyzed in the use process can be effectively overcome. The suspending agent has the remarkable advantages of high efficiency, low toxicity, broad spectrum, low cost, safety, environmental friendliness and the like.

Description

Avermectin is prevented the anti-oxidant suspending agent of photodissociation

Technical field

The present invention relates to a kind of agricultural chemicals, particularly Avermectin.

Background technology

Avermectin have tag, stomach toxicity, low toxicity, wide spectrum, penetration be strong; It is a kind of macrolide disaccharide compounds, is the natural products that separates from edaphon, insects and mites is had tag and stomach poison function and faint fumigation action is arranged, and without systemic action, ovicidal not; It has very strong osmosis to blade, can kill subepidermal insect.What its mechanism of action was different from general insecticide is that it disturbs neurophysiology movable, stimulate and discharge the r-aminobutyric acid, and the r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, if the larva that the mite class becomes mite and insect with paralysis symptom namely appears after medicament contacts, inertia does not take food, and is dead after 2-4 days.Because not causing that insect dewaters rapidly, so its lethal effect is slower.Though predatism and parasite there are direct killing effect, because plant surface is residual few, therefore little to the damage of beneficial insect.

Avermectin is exposed in the air oxidized easily, is decomposed easily at strong UV-irradiation.

Summary of the invention

Drug effect and the product safety environmental-protecting performance of the present invention in order to improve Avermectin made suspending agent to Avermectin, and in the Avermectin suspending agent, add antioxidant, light stabilizer, ultraviolet absorber.

Antioxidant is the BHT(Chinese name: antioxidant 264, chemical name: 2,6-di-tert-butyl-4-methy phenol or dibutyl hydroxy toluene), light stabilizer is two (2,2,6,6-tetramethyl-4-piperidyl) sebacate, ultraviolet absorber are 2-(2'-hydroxyl-3'-tertiary butyl-5'-aminomethyl phenyl)-5-chlorobenzotriazole.Auxiliary agent is dispersant NNO(di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate), peaceful breast 34 ^#(polystyrene-based phenol formaldehyde resin APEO), farming breast 500 ^#(calcium dodecyl benzene sulfonate), aluminium-magnesium silicate, Sodium Benzoate, ethylene glycol, defoamer.

The anti-oxidant suspending agent of anti-photodissociation of Avermectin of the present invention comprises Avermectin, antioxidant, light stabilizer, ultraviolet absorber, auxiliary agent and water, and its weight portion proportioning is:

Avermectin: 5-30%,

BHT：0.1—0.2%、

Two (2,2,6,6-tetramethyl-4-piperidyl) sebacate: 0.1-0.3%,

2-(2'-hydroxyl-3'-tertiary butyl-5'-aminomethyl phenyl)-5-chlorobenzotriazole: 0.1-0.2%,

Auxiliary agent: 12-15%,

Water is mended to 100%.

Described auxiliary agent is formed by the total weight parts proportioning by following ingredients:

NNO：0.7—2%、

Peaceful breast 34 ^#: 4-5%,

Farming breast 500 ^#: 1-3%,

Aluminium-magnesium silicate: 1-2%,

Sodium Benzoate: 0.1%,

Ethylene glycol: 5%,

Defoamer: 0.2%.

Beneficial effect of the present invention: can effectively overcome the drawback of in use oxidized photodissociation of Avermectin, have the advantages such as significant efficient, low toxicity, wide spectrum, cost are low, safety and environmental protection.
