Insecticides fungicides acaricides herbicide characteristics summary

Emamectin benzoate
The activity of insecticidal, acaricidal and nematicidal is increased by 10-100 times, and the insecticidal spectrum is broadened; the stomach toxicity is mainly combined with contact; the pests irreversibly paralyze, stop eating, after 2-4 days In order to die, the insecticidal rate is slower; the duration of the effect is long, the pests are 10-15 days, and the cockroaches are 15-25 days. It has no systemic properties for crops, but it can penetrate into epidermal tissues; it has extremely high activity against lepidopteran pests, mites, coleoptera and homopteran pests, and it is not easy to make pests resistant to insects; Degradation; high safety for all crops at protected sites or 10 times the recommended dosage; a second insecticidal peak occurs over 10 days;
Nicotine; contact, stomach poisoning and systemic absorption; pest paralysis death; good quick-acting, high control effect in 1 day, residual period up to 25 days; high temperature insecticidal effect; sucking mouthparts Pests; easily absorbed by crops and distributed to the top, with rooting action;
Promote the lepidopteran larvae molting; contrary to other mechanisms that inhibit larval molting; effective for both older and younger larvae; stop feeding for 6-8 hours (stomach toxicity), more rapid than ecdysone inhibitors, 3 ~ 4 days after the start of death; no phytotoxicity, safe for crops, no residual drug spots;
When the temperature is low, the virulence is reduced, and the dosage or concentration of the drug can be appropriately increased; the chewing mouthparts and the sucking mouthparts pests; the contact and stomach toxicity, certain fumigation and osmosis; the knocking force of the pests is strong, the high temperature The effect is good; the residual effect period is short; for sorghum, melon beans and pears, grapes, cherries and other varieties susceptible to phytotoxicity, should be used with caution; 10 days before fruit picking.
In the early larval stage, the older the insect, the worse the control effect. Inhibition of chitin synthesis; stomach toxicity, can invade the epidermis of insects and eggs, but no systemic effect; spray on the back of plant leaves; efficacy period of up to 30 days, resistant to rain erosion; safe against natural enemies It has high activity against lepidoptera and mosquito larvae; it begins to die 3 days after the drug, and reaches the peak of death in 5 days; it is ineffective for adults;
