How to Correctly Use Abamectin for Pest Control
Abamectin is a new effective broad-spectrum antibiotic insecticide and miticide, commonly used by the majority of farmers for agricultural production. Other trade names are insects and mites grams, insects and mites light, Avi clear and abamectin insecticide, etc. The formulations on the market are generally 1.8%, 2%, 1% cream, 0.12%, 0.05% WP, 3%, 5 % of particles, etc., Besides, there are some mixed agents (such as cypermethrin, phoxim, dichlorvos and other mixed).
Abamectin is a broad spectrum insecticide with contact and stomach action on miticide, pests, mites, and it has seepage effect, but no ovicidal properties. Its insecticidal mechanism is to interfere with pests’ neurophysiological activity, mainly playing a role in nerve and muscle joints, increasing the release of chloride ions, which inhibit the transmission of information neuromuscular junction, causing insects or mites paralyzed, inactive, no feeding, dead after 2 ~ 4 days. Different from the mechanism of action of commonly used insecticides, it does not have cross-resistance to insecticides commonly used, suitable for prevention and treatment of pests resistant to organophosphate or pyrethroid insecticides. Abamectin degrades in soil and photolyse quickly; safe to crops; usually without phytotoxicity; mainly used to control caterpillars, cotton bollworms, diamondback moths, leafminers, spider mites and yellow tea, and for root-knot nematodes, worms and other soil pests leek as well. For the prevention and treatment of pieris, with 1.8% Abamectin EC in 2500~3000 times, evenly spray; for bollworm pest, with 1.8% clear avermectin EC, 0.75 ~ 1.5 g/667m2, watered spray; for dishes moth larvae or eggs in the young hatch peak, with a 1.8% avermectin EC in 2500~3000 times, evenly spray; for red spiders on cotton, fruit and vegetables, yellow tea mites, with 2.0% abamectin in 4500 times, evenly spray. According to the characteristics of pests and mites, decide whether the time of spraying is in the morning or evening, but avoid the heat of midday. For the control of vegetable root-knot nematodes, worms and other soil pests leek in breeding period, use 1 ml of 1.8% Ai Fuding EC per square meter of seedbed, spray after mixed with 1 kg water(diluted 1000 times); When planting, with 1.8% Ai Fuding EC at 1 ml/m2, spray the soil surface in 1000 times diluted.
Before using avermectin, we should be noted that the type of drug used, content, application area and control objects, such as the active ingredient are in strict accordance with the requirements, correctly choose the spraying area required for medicinal liquid and prepare accurate concentration in order to improve the control effect. Don’t increase or decrease the pesticide active ingredient dosage per 667 m2. Medication should be done on a cloudy day or evening, avoid spraying in the sun; liquid should be prepared according to the need as storage is no available; when spraying, both sides of leaves, the stem and shelter are to be sprayed, make sure nowhere is missed.
For some pesticides can be completely controlled by conventional hazards vegetable pests, abamectin supplier reminds you do not use avermectin; for some borer pests or insects with resistance to conventional pesticides, avermectin is suitable. Long-term, single-use of avermectin is not recommended in case the pests may have resistance, better to be rotated with other types of insecticide; for vegetables, use with a maximum of 1 or 2 times each season, interval of 7 days, maximum residue limit of 0.05 mg/kg. Pay attention to that the use is no harm to rivers, reservoirs, water and flowering crops when honey bees are gathering honey; do not spray on vegetables or crops during their flowering period, in order to avoid phytotoxicity.
