The pure Methomyl is white cystal powder.Melting point:78-79¬-C vapors pressure: 6.67mPa(25¬-C),Density(25/40¬-C)1.295g/ml,soluble in acetone, methyl alcohol, chloroform. It's not stable with acid and alkali.
It consists of rough product and refined product. The content of rough product is about 95% of the total, and it is white solid powder.The content of refined product is no less than 98% of the total, and it is white crystal. Methomyl oxime is melted at 90-92, freely soluble in water, acid and at high temperature. It is intermediates for making methomyl. Its toxicity is lower than methomyl's. It is also a kind of depressant for acetyl acid choline lipase.

Product name: chlorfluazuron
Physical and chemical properties:
White crystals, melting point 226.5 (decomposition), vapor pressure <10npa (20 ), the water solubility under 20 <0.01mg/l, hexane <0.01, n-octanol 1 xylene 2.5, methanol 2.5 , toluene 6.6, isopropyl alcohol 7, dichloromethane 22, acetone 55, cyclohexanone 110 (g/l, 20 ), stability in the light and heat.
The model of function:
Stomach toxicity, contacted death (chitin synthesis inhibitor)
Toxicity:
Acute oral ld50 > 8500mg/kg acute percutaneous ld50:> 1000mg/kg
Characteristics:
The mechanism of it is the inhibition of chitin synthesis, impeding the normal insect molting. As results, the eggs hatching, the larvae molting and pupal developmental appear deformity, adult eclosion is blocked, and tis product with high efficacy, the role of slow for a variety of lepidoptera pests as well as the orthoptera, coleoptera, hymenoptera, diptera, such as high activity, but aphids, leafhopper, planthopper invalidá
