What pests does pyridyl ether control?

Pyriprodione has special effects on insects such as HOMOPTERA, LEPIDOPTERA, COLEOPTERA and Neuroptera, and has special effects on whiteflies and scale insects. Its mechanism of action is: inhibiting the activity of insect pharynx, interfering with the biosynthesis of molting hormone in larvae, making eggs unable to hatch normally, larvae unable to molt completely, and finally dying.

The main products of pyridaben are 65,438+000 g/L EC, 65,438+00% pyridaben SC (containing 2.5% pyridaben +7.5% imidacloprid) and 8.5% methomyl pyridaben EC (containing 0.2% emamectin benzoate +8. 3% pyridaben).

1. Used for vegetable pests: for controlling tomato whitefly, 35-60ml100g/L EC or 30-50ml 10% pyridaben suspension can be sprayed with water; Another example is the control of diamondback moth, which can be sprayed with 70-80ml of 8. 5% methyl nipagin emulsifiable concentrate per mu.

2. Utilization of fruit tree pests: for example, the control of psylla on citrus and pear trees can be used in two optimal control periods. The first time is the peak of oviposition of psyllid, and 5% pyridaben microemulsion 1500 times can be used for adults together with efficient chemicals, and can be beaten twice continuously; The second time is at the peak of hatching of psyllid eggs, 5% pyridaben microemulsion 1000 times +20% dinotefuran suspension 1000 times can be used for garden spraying, and the interval is about 10 day, and the spraying should be thorough and uniform.
