A detailed guide to the application technology of phenthoate: master the correct method of use

50% Miechonglu emulsifiable concentrate (phenthoate) is an organophosphorus insecticide with moderate toxicity (only 1/30 that of methamidophos). It also has stomach-poison and contact-killing effects, and gives good control of various pests on many crops such as rice, cotton, vegetables and fruit trees. It is especially outstanding against rice stem borers, and no pest has yet developed resistance to it. The application technology of this insecticide is described below:

1. Use technology:

1. To control rice striped stem borer and rice yellow stem borer, use 100-120 ml of 50% Miechonglin emulsifiable concentrate per mu, add 50 L of water, and spray evenly and finely on the crops. Used before the peak hatching period of the stem borers, it can effectively control stem borer damage; at the same time it also controls pests such as rice planthoppers and rice leafhoppers.

2. For rice leaf roller, spray 150 ml of 50% Miechonglu emulsifiable concentrate per mu at the peak of the second-instar larvae (before leaf rolling), which can effectively control leaf roller damage.

3. For pests on various vegetables such as aphids, cabbage caterpillars, diamondback moths and beet armyworms, use 120-150 ml of 50% Miechonglu emulsifiable concentrate per mu plus 50 L of water for fine spraying, with outstanding control effect.

2. Precautions:

1. 50% Miechonglu emulsifiable concentrate is safe for most aquatic animals, but it is toxic to @#@255@#@. When applying, keep away from bee-release areas and nectar source plants.

2. Pay attention to safe pesticide use and labor protection; apply pesticide between 10:00 and 16:00 in hot seasons. Once symptoms of poisoning appear, conventional organophosphorus antidotes can be used.

3. Pesticide application should use misting and fine spraying to improve the control effect and reduce environmental pollution.
