2, Dimethylfuran: eggplant, pepper, tomato open field before transplanting with 33% pendimethalin 100-150g water sprayed on the surface. Cover the field to reduce the amount of medication.
3, oxyfluorfen: eggplant, pepper, tomato open field before transplanting with 24% oxyfluorfen 50-60g water spray, the film field should reduce the amount of medication.

2. Dilamine: Sprayed with 48% dilamine 200-300g per acre before sowing and before transplanting.
3, dimethyl amylamine: before sowing or before transplanting, per acre with pendimethalin 100-150g with water spray.
The above is the technology related to the control of weeds in vegetable fields compiled by Huinong. Many farmers are blindly weeding and use pesticides during the growth of vegetables.
