Function characteristics

Diazinon phosphorus is a broad-spectrum organophosphorus insecticide, which has contact killing, stomach toxicity, fumigation and certain systemic effects. Its mechanism of action is to inhibit ethylcholinesterase. It has a good preventive effect on various pests such as Lepidoptera and homoptera, and can also be used for seed dressing to control underground pests.

Application scope

Diazinon phosphorus can be used to control cotton aphids (active ingredient 20-30g/ mu), cotton red spider (active ingredient 30-40g/ mu), cabbage worm (active ingredient 20-25g/ mu), vegetable aphids (active ingredient 20-25g/ mu), onion leaf miner, bean seed fly (active ingredient 20-25g/ mu), rice stem borer and rice stem borer (active ingredient) 25-37g/ mu, rice lean mosquitoes (active ingredient 20-25g/ mu), rice planthoppers, rice leafhoppers, rice stem miners (active ingredient 25-37g/ mu), underground pests of corn, wheat and peanuts (active ingredient 20-250g/ mu).

Application

1. 40% Diazinon phosphorus emulsifiable concentrate as foliar spray for pest control on rice corn and other crops has a longer duration of effect and is widely used, especially against flies.

2. The application of 2.10% Diazinon phosphorus granules

(1) Control underground pests of tobacco. The underground pests that harm tobacco mainly include grubs, cutworms and crickets, etc., which cause tobacco to lack ponds. When transplanting tobacco, apply 0.5 to 1 gram of 10% diazinon granules per plant in the pond, then cover the soil and water. This can fully exert its contact killing and fumigation effects to kill pests.

(2) Control underground pests of sugarcane. For the initial planting of sugarcane, after sowing, mix 2 kilograms of 10% diazinon granules with 5 kilograms of fine soil and sprinkle it into the planting furrow, then cover it with soil. This can effectively kill underground pests and protect the sugarcane roots and buds from damage. In the early spring, for persistent sugarcane, combined with loosening the soil, during the period of sugarcane bud germination, mix 2 to 3 kilograms of 10% Diazinon phosphorus granules per mu with 10 kilograms of fine soil, sprinkle it around the roots, and then loosen the soil to cultivate the roots, so that the medicinal soil is buried around the roots to exert its contact killing and fumigation effects.

(3) Control mango root scale insects and apple root phylloxera, etc. When fruit trees are subjected to winter soil management. After digging up the soil around the roots, mix 2 to 3 kilograms of 10% diazinon granules with 10 kilograms of fine soil. Apply 300 to 500 grams of the medicine to each plant and sprinkle it into the dug soil. Then dig it up again until the medicinal soil is turned into the soil.

(4) Control yellow ants on marigolds and other crops. In the cultivation of marigolds and other crops, the damage caused by leecules and ants in some local areas is also very serious. 10% diazinon granules can be mixed with 1-2 kilograms of fine soil per mu and 5-10 kilograms of fine soil. After transplanting marigolds and other crops, it can be scattered around the roots, and then the soil can be piled up, watered and covered with film.
