It is understood that since the start of the pilot demonstration project of the alternatives of highly toxic pesticides since 2005, the Ministry of Agriculture has recommended the alternatives for four batches of “methamidophos, parathion, methyl parathion, monocrotophos, P amines” and 5 varieties of organophosphorus highly toxic pesticides, in which the alternative pesticides for preventing vegetable pests are as follows:
1. The control and prevention of vegetable aphids. Imidacloprid, recommended dose of 1-2g active ingredient / mu; acetamiprid, recommended dose of 0.45-0.6g active ingredient / mu; pymetrozine, 5g active ingredient; pyrethrin, 1.8g active ingredient; sophocarpidine, 0.4g active ingredient; imidaclothiz, 2g active ingredient. Spray at the beginning of the peak period of aphid.
2. Vegetable Bemisia tabaci. Imidacloprid, recommended dose of 2g active ingredient / mu; bifenthrin, recommended dose of 0.75g active ingredient / mu. Spray at the beginning of the peak period of bemisia tabaci.
Acetamiprid, 2.5g a. i. / mu (for example 3% acetamiprid EC 83 ml / mu); thiamethoxam, 4g a. i. / mu (e.g. 25% thiamethoxam WG 16g / mu). Spray at the beginning of the peak period of nymphs.
3. Control and prevention of beet armyworm. Chlorfenapyr, recommended dose of 5g active ingredient / mu; Fufenozide, recommended dose of 6g active ingredient / mu; indoxacarb, recommended dose of 2.4g active ingredient / mu; hexaflumuron active ingredient 2.5-3.5g / mu (for example, 5% hexaflumuron EC 50-70 ml / mu); chlorpyrifos active ingredient 20-24g / mu (for example, 40% chlorpyrifos EC 50-60 ml / mu); methylamine Kiah Ivermectin, active ingredient 0.3-0.5g / mu (for example, 1% Emamectin EC 30-40 ml / mu), spray once for 50kg of water. It is suggested that spray be done when beet armyworm are at younger age (before the 2nd instar of larvae).
Tebufenozide + chlorpyrifos, 24g active ingredient (4g tebufenozide + 20g chlorpyrifos); flubendiamide, 3g active ingredient. Spray evenly at the peak period of beet armyworm, and when most of the larvae are under the 2nd instar.
4. Control and prevention of diamondback moth. Emamectin, recommended dose of 0.15-0.25g active ingredient / mu; fipronil, recommended dose of 1-2g active ingredient / mu; chlorfenapyr, recommended dose of 3.35-5g active ingredient / mu; indoxacarb, recommended dose of 3g active ingredient / mu; chlorfenapyr, 5-6g active ingredient / mu (e.g. 10% chlorfenapyr SC 50-60g / mu). Spray once for 50 liters of water; flubendiamide, 3g active ingredient. Spray from the peak period of diamondback moth till when the larvae are at the 2nd instar.
5. Control and prevention of grasses maggots. 160g Chlorpyrifos active ingredient; dilute with water when the leek shows early symptoms of disease (soft yellow tips, lodging), and pour evenly on the roots at the chives; 400g diazinon active ingredient, when the leek shows early symptoms of disease, mix the granules with soil, spread the mixture after it becomes uniform, and then irrigate thoroughly to ensure the efficacy of the pesticide. 30g Cyromazine active ingredient; 480g phoxim active ingredient. Dilute with water when the leek shows early symptoms of disease, and pour evenly on the roots at the chives.
