What is spinosad

Light grayish white solid with a slightly scented earthy odor. The vapor pressure is about 1.3 x

10-10 Pa. In an aqueous solution of pH 7.74, the metal and metal ions were relatively stable

within 28 days. The half-life of photodegradation in soil is 9-10 days; the half-life of water

photolysis is <1d. It is relatively stable in aqueous solution in the range of pH 5-7; half-life >200d

at pH 9. Spinosad is a mixture of more than ten components, the main components being A and

D. The melting point of spinosyn A is 84-99.5 ° C, the vapor pressure is 3.2×10-10 Pa, and the

solubility in water is 290 mg/L (pH=5.0), 235 mg/L (pH=7.0), 16 mg/L (pH= 9.0); the partition

coefficient is 2.8, 4.0, 5.2 at the corresponding pH values. Spinosad D has a melting point of

161.5-170 ° C, a vapor pressure of 2.1×10-10 Pa, and solubility in water: 29 mg/L (pH=5.0),

0.332 mg/L (pH=7.0), and 0.053 mg/L ( pH=90.0); the partition coefficients were 3.2, 4.5, and 5.2 at the respective pH values.

The application of SPINOSAD:

The new biocide, with its unique chemical structure and safe and quick-acting properties, has won

the US President's Green Chemical Challenge Award for its low toxicity, low residue and safety. It

works by stimulating the nervous system of the insect, causing non-functional muscle contraction

and failure, accompanied by twitching and paralysis. Consistent with the activation of the nicotinic

acetylcholine receptor, in addition to the gamma-aminobutyric acid receptor, further contributing to

the increased insecticidal activity. This mode of action is favored by people. Spinosad can

effectively control Lepidoptera (such as Plutella xylostella, beet night butterfly, etc.), Diptera and

Thysanoptera pests, and can also effectively control some of the large number of insects that

invade the leaves of Coleoptera and Orthoptera. kind. Sucking insects and mites cannot be effectively prevented.
