Shachongshuang (shachongdan) is a highly effective, low-toxic, low-residue organic nitrogen insecticide, with 25% and 30% aqueous formulations. The agent has strong contact and stomach poisoning effects on leaf miners, wind butterflies and other pests, and also has a certain fumigation and oviogenous effects. It is moderately toxic to humans and animals, and has little toxicity to aquatic organisms, with a residual toxicity period of about 2 months. When using, the 25% liquid is 600~800 times the water.
Difangdian can control the following pests of dryland crops:
⑴ When the new shoots are 2~3 mm long, which is the early stage of new shoots germination, or when 50% of the shoots are extracted from the field, the citrus leaf miner shall be sprayed with 600~700 times solution of 18% insecticide double water agent, and then sprayed every 7 days or so. 1 time. For the prevention and control of Bodhidharma swallowtails, spray with 25% water and 600 times solution during the hatching period.
⑵Plutella xylostella and Plutella xylostella are sprayed with 100-150 ml of 25% water solution per mu before the larvae’s 2~3 instar peak period. For controlling Plutella xylostella, it is better to mix it with B.t., use 150 ml of 25% insecticide double water per mu and 200 ml of R t. to spray on the water. To prevent and control the water stem borer, at the end of the egg incubation period, use 150-250 ml of 18% aqueous solution per mu and add 50 kg of water to spray; or 18% aqueous solution 500 times to infuse.
⑶ Tea loopers, tea moths and small green leafhoppers are sprayed with 18% aqueous solution 500 times.
⑷In the sugarcane seedling stage, use 200~250ml of 25% water for the sugarcane seedlings and large moths per mu, add 250~300 liters of water and pour the sugarcane seedlings, and then apply the medicine once every 7 days or so.
