Product Description
Avermectin by Omura Kitasato University in Japan and the United
States and other intellectual Merck company first developed a class
of six-membered macrolide compounds having insecticidal,
acaricidal, nematicidal activity by Streptomyces griseus
Streptomyces avermitilis fermentation. Natural avermectin contains
eight components, there are four kinds namely A1a, A2a, B1a and
B2a, the total content ≥*0%; corresponding to four smaller
proportion of homologs is A1b, A2b, B1b and B2b , the total content
of ≤*0%. Avermectin pesticide is currently marketed as a main
insecticidal ingredient abamectin (Avermectin B1a + B1b, B1a which
not less than *0%, B1b no more than 5%), with the content of B1a to
calibration. Since ***1 harm pole off (abamectin) after entering
the market of pesticides, avermectin pesticide plays more important
role in the prevention and control system of pests. Avermectin in
China currently has more than *0 production, currently marketed
avermectin series pesticides abamectin, ivermectin and emamectin
benzoate. Of the late ***0s, developed by the Shanghai Institute of
pesticides in soil is separated from Guangdong Jieyang screened
***1 strain, after analysis proved that strain S.avermitilis
Ma****0 is similar to the same chemical structure and avermectin.
***3 Beijing Agricultural University New Technology Development
Corporation project research and production development of this
drug. Avermectin is a new antibiotic class, a new structure, dual
characteristics of farm animals. With the improvement of people's
living standards as well as the call for green food, bio-pesticides
in current pesticide market in the acclaimed, pundits predicted
that the *1st century will be the century of biological pesticides.
It is reported that the European bio-pesticides will rise in ***7
sales of $ **0 million to $ **9 million in ***4. Avermectin is a
new biological pesticide products are currently the most popular
market and a competitive nature.

years. Toxicity: According to Chinese pesticide toxicity grading
standards, avermectin is a highly toxic pesticides. The original
drug acute oral LD*0 of l0 mg / kg, acute oral LD*0 of *3 mg / kg,
rabbit acute percutaneous LD*0 greater than ***0 mg / kg in rats
with acute percutaneous LD*0 greater than **0 mg / kg, large rat
acute inhalation LC*0 greater than 5.7 mg / l. No skin irritation,
slight irritation of the eyes. In the experimental dose on animals
no teratogenic, carcinogenic, mutagenic effect. Three generations
of breeding experiments in rats, no effect at a dose of 0.*2 mg /
kg / day. Two years had no effect in rats at a dose of 2 mg / kg /
day. Highly toxic to aquatic organisms, trout LC*0 *6 hours was 3.6
micrograms / liter, bluegill sunfish *6 hours LC**9.6 micrograms /
liter. Highly toxic to bees, oral LD*0 of 0.**9 g / head contact
LD*0 0.**2 g / head, but left in the foliage of LT*0 was 4 hours
after drug remaining in the foliage of four hours of low toxicity
to bees. Low toxicity to birds, quail acute oral LD*0 greater than
***0 mg / kg, ducks acute oral LD*0 of *6.4 mg / kg. Acute oral
LD*0 of **0 formulation mg / kg, rabbit acute percutaneous LD*0
greater than ***0 mg / kg. Acute inhalation LC*0 of 1.1 mg / liter.
To the eyes and skin stimulation. Abamectin EC formulation of 1.8%
