We supply Spinosad powder

Spinosad powder is a naturally being germicide that's deduced from a soil bacterium. It's an effective volition to synthetic fungicides and has been set up to be largely effective against a wide range of nonentity pests, including caterpillars, thrips, and leafminers. it has a unique mode of action that widely targets the nervous system of insects, making it less dangerous to salutary insects and the terrain. Our Spinosad greasepaint is a high- quality product that's manufactured to strict quality norms. It's easy to use and can be applied to a variety of crops, making it an ideal result for organic and conventional husbandry likewise.

What is Spinosad powder?

Spinosad is a macrolide grounded, pollution-free and effective natural germicide uprooted from the turmoil broth of Saccharopolyspora spinosa in sugarcane. Its chemical formula is C42H71NO9. The parent strain of soil actinomycete Saccharopolyspora spinosa Metrz & Yao, which produces multi pesticides, was originally insulated from an abandoned winery in the Caribbean. Experimenters from Dow Agro lores in the United States have set up that this bacterium can produce composites with veritably high insecticidal exertion. The practical product is a admixture of spinosyn A and spinosyn D, hence the name spinosad.

Chemical property

it is Light argentine white solid chargers with a slight odor of aged soil. The vapor pressure is about1.3 × 10- 10Pa. In an waterless result with a pH of7.74, essence and essence ions are fairly stable within 28 days. The half- life of photodegradation in soil is 9- 10 days; The half- life of water photolysis is lower than 1 day. fairly stable in waterless result within the pH range of 5- 7; At a pH value of 9, the half- life is> 200 days. Multifungin is a admixture of further than ten factors, with the main factors being A and D. The melting point of streptomycin A is 84-99.5 ℃, the vapor pressure is3.2 × 10- 10Pa, and its solubility in water is Chemicalbook 290mg/ L( pH = 5.0), 235mg/ L( pH = 7.0), and 16mg/ L( pH = 9.0), independently; The distribution portions under corresponding pH conditions are2.8,4.0, and5.2, independently. The melting point of multi germicide D is161.5
170 ℃, with a vapor pressure of2.1 × 10- 10Pa. Its solubility in water is 29mg/ L( pH = 5.0),0.332 mg/ L( pH = 7.0), and0.053 mg/ L( pH = 90.0), independently; The distribution portions under corresponding pH conditions are3.2,4.5, and5.2, independently.

What is the application of Spinosad powder?

1. Spinosad powder is a new type of biological insecticide with a unique chemical structure that combines safety and quick efficacy. It has won the President's Green Chemical Challenge Award in the United States for its low toxicity, low residue, and safety. Its mechanism of action is to stimulate the insect's nervous system, leading to non functional muscle contraction, failure, and accompanied by tremors and paralysis. Consistent with the activation of nicotinic acetylcholine receptors, it also acts on γ- Aminobutyric acid receptors further enhance their insecticidal activity and enhance their chemical reactivity. This mode of action is favored by people. Multifungicides can effectively control pests in the order Lepidoptera (such as diamondback moth, beet night butterfly, etc.), Diptera, and Thymidoptera, and can also effectively control certain species of pests in the order Coleoptera and Orthoptera that consume large amounts of leaves. Unable to effectively control sucking insects and mites.

2. It should be used to control Lepidoptera larvae, thrips, and leafminer, and has good control effects on diamondback moth, beet armyworm, leafminer, thrips, striped armyworm, and bean pod borer.

Production methods

A new microbial strain, Saccharo polysporaspinosa, or a mutant strain capable of producing multiple fungicides. Produce aerial mycelium on both composite and synthetic media. The color of the airborne spore group is mainly light yellow pink, with some white, and the reverse side is yellow to yellow brown, without obvious pigment deposition. The seed culture medium for fermenting and cultivating multi fungicidal spore bacteria is: enzymatic hydrolyzed soybean hydrolysate 3%, yeast extract 0.3%, MgSO4 · H2O 0.2%, glucose 0.5%, maltose 4%, 1L deionized water, sterilized at 121 ℃ for 30 minutes. The vaccination amount is 10%. The preferred carbon sources for large-scale production are glucose and maltose, as well as ribose, xylose, fructose, galactose, mannose, mannitol, soluble starch, potato dextrin, methyl oleate, oils, etc. The preferred nitrogen sources are raffinose, peptone milk, and digested soybean powder. Fish meal, corn extract, yeast extract, hydrolyzed casein, beef extract, etc. can also be used. Inorganic salts added to the culture medium can produce conventional soluble salts such as zinc ions, sodium ions, magnesium ions, ammonium ions, chloride ions, carbonate ions, sulfate ions, nitrate ions, etc. In addition, the culture medium should also contain necessary trace elements for microbial growth and development. If there is foaming problem, soybean oil can be added to the culture medium to inhibit foaming. The cultivation temperature for multi fungicidal fungi is 24-33 ℃, and the optimal temperature for producing multi fungicides is 28-30 ℃. During industrial fermentation, the dissolved oxygen in the tank should be maintained at 60% or above, preferably at 65% or above, through ventilation and stirring speed. The pressure inside the tank is 0.034MPa. After 7-10 days of fermentation for separation and extraction, an equal volume of acetone was added to filter and remove the bacterial cells. The filtrate was adjusted to pH 13, and resin adsorption was carried out. Polyfungin A and D were eluted using a gradient solution of 0-95% methanol: acetonitrile=1:1 (containing 0.1% sodium acetate). The elution solution was collected in sections to obtain a polyfungin containing eluent, which was then concentrated to obtain a polyfungin concentrate. Dilute the concentrated solution with petroleum ether, place it on a silica gel chromatography column, elute with petroleum ether and methanol gradient, collect in sections, and obtain the elution solutions of multi fungicides A and D. Analyze and detect high-performance liquid chromatography (HPLC). Column: ODS-AO, liquid phase: acetonitrile/methanol/water=40/40/20 (containing 0.05% ammonium acetate), flow rate of 3mL/min, detection wavelength: 250nm.
