The Avermectin Fermentation Antibiotics Insecticide

Product description：it can kill mites and bugs, but now not eggs. the mechanism of movement is different from the overall insecticide is to intrude with neurophysiological sports, stimulate the discharge of γ -aminobutyric acid, and aminobutyric acid on arthropod nerve conduction inhibition. person mites, nymphs and insect larvae display paralysis after touch with avermectin, do not circulate or feed, and die in 2 ~ 4 days. the lethal effect of abamectin is slow as it does not cause speedy dehydration of insects. although abamectin can at once kill predatory bugs and parasitic natural enemies, it has little harm to useful insects because of the small amount of residue on plant floor. abamectin is adsorbed with the aid of soil inside the soil and will now not circulate, and is decomposed by means of microorganisms, so it has no cumulative impact within the environment and can be used as an integral part of complete manage. it is easy to prepare and can be used by pouring the instruction into water and stirring a little. it is also more secure for crops.

Usage：
