How can paraquat herbicide be safe?

How can paraquat herbicide be safe? Paraquat herbicide is a kind of insecticidal herbicide, which is generally used to kill annual or perennial weeds. However, paraquat contact with soil will reduce its activity, so it can not play a good role in killing the underground rhizomes of weeds. In recent years, farmers are often used to control weeds in corn fields, and some of them cause drug damage due to improper use. Therefore, the safe and effective use of paraquat herbicides is very important for crops, humans and animals, and the safe and effective measures and methods must be kept in mind in the process of use. 1. Paraquat has a strong destructive effect on green tissue, and the liquid should be sprayed evenly on the green stems and leaves of weeds as far as possible. 2. Light can accelerate the efficacy of paraquat, so it has a very good effect on weed control in sunny weather. 3. Corn fields can be treated with pre-sowing treatment or post-sowing pre-seedling treatment, and protective directional spray can also be used to control inter-row weeds during crop growing period. Pre-sowing or post-sowing pre-seedling treatment, use 20% water agent 75-200 ml per mu, spray 25 kg of water to control unearthed weeds. During the crop growing period, use 20% water agent 100-200 ml per mu and 25 kg of water for inter-row protective directional spray. Do not drift the liquid onto corn or other crops. 4. Paraquat is very toxic to people, so it is necessary to take full personal protective measures. Click to get more herbicide application techniques
