Biological pesticides control three characteristics of Liriomyza sativae

Liriomyza sativae has a heterozygous diet, is highly harmful, and spreads quickly, making it difficult to prevent it completely. It has caused great harm to vegetable production.

Liriomyza sativae is the most widely protected vegetable and open vegetable, such as beans, cucumber, loofah, tomato, eggplant, etc., and is suitable for the prevention and control of Liriomyza sativae. The application of biological pesticides to control Liriomyza sativae has achieved good results in recent years. The first choice of biological pesticides is 0.2% of Avermaria emulsifiable concentrate and 1000% of 25% chlorfenapyr suspension. The insecticidal effects of the two agents can reach over 95%.

The effective ingredient of avidin is avermectin, and the common name in China is “qiqisu”. It is an antibiotic produced by microbial fermentation; it is a nerve signal blocker in most agricultural pests.

Diflubenzuron III is an inhibitor of insect chitin synthase and belongs to insect growth regulators. The insecticidal mechanism is to inhibit the synthesis of chitin in insects, so that Kunsheng can not peel and die normally.

There are three major characteristics in the control of Liriomyza sativae with the application of Avivis and Diflubenzuron.

1. The control effect is good and the residual effect period is long. 0.2% Avicel ECG 1500 times or 25% Diflubenzuron No. 3 1000 times liquid to control Liriomyza sativae, the effect can reach more than 95%, and the residual effect period is 20 days.

2. Safety to natural enemies and environmental safety. Avidin and Diflubenzuron No. 3 have little damage to natural enemies and are ideal agents for comprehensive prevention and treatment. These two drugs are environmentally friendly, low-toxic, low-residue, and meet the requirements for the production of “no pollution” vegetables.

3, for crop safety, in the case of increasing the dose multiple times, the application of these two drugs, most vegetables are not phytotoxic.

The application of Aviline and Diflubenzuron No. 3 to control the control period of Liriomyza sativae is in the larval stage, spraying once every 7 days, even spraying 2 to 4 times. The above two agents may be used alone or alternately. Spray carefully. It is best to add 1000 times of pesticide synergist to the liquid to increase the permeability, spreadability and adhesion of the agent, so that the drug is more effective and longer lasting.
