What herbicide should be used in open-field cilantro plots? Should it be applied before emergence or after emergence? We also ask knowledgeable readers to help explain.Common weeds in cilantro plots include purslane, goosegrass and others. These weeds are usually mixed in among the cilantro, and hand removal is not only troublesome but they also regrow quickly. Therefore, Zhongdiwang has compiled the methods for using herbicides to control weeds in cilantro plots. The following are listed in detail for readers' reference.
Method 1. Use pre-emergence herbicides:
You can use pendimethalin, trifluralin and others. Use 33% pendimethalin at 100-150 ml per mu, and spray the soil surface after sowing. For 48% trifluralin, the weed-killing effect is best when mixed into the soil. In soil it can be strongly adsorbed by clay colloids and soil organic matter, so it is not easily leached. Use 150-200 ml per mu, dilute with 45 kg of water and spray the soil, then immediately mix the soil with a nail rake, and sow after 5-7 days.
Method 2. Weed control methods after weeds have grown:
Choose herbicides such as haloxyfop-R-methyl or quizalofop-p-ethyl. At the 2-3 leaf stage of weeds, use 15% refined haloxyfop-R-methyl emulsifiable concentrate at 30-80 ml per mu, or 6.9% quizalofop-p-ethyl emulsion at 50-60 ml per mu, dilute with 45 kg of water and spray the stems and leaves of the weeds.
Precautions for using herbicides in cilantro plots:
Precaution 1. For herbicides used to treat soil, before use it is best to level the soil bed surface and ensure the soil is fine and crumbly, so that the effect after treatment is better.
Precaution 2. When using herbicides on stems and leaves, it is best to choose clear and windless weather for spraying, to avoid drifting with the wind onto other crops and harming them.
