Paraquat herbicide use
Paraquat is one of the most common herbicides. As the name suggests, paraquat is effective against all kinds of weeds. The traditional method of using paraquat is direct spraying with water. Agriculture is a traditional industry. It is not too concerned about the correct use of paraquat. Often, because of these concerns, there will be various phytotoxicity problems, so the Chinese pesticide net Xiaobian once again popularizes the use of paraquat herbicides:
Paraquat herbicide is a fast-killing herbicide with contact and certain systemic action. It is generally used to eliminate annual weeds or perennial weeds. Of course, the toxicity of paraquat to humans is also well known, so care must be taken when spraying paraquat.
Paraquat herbicide use:
1. Paraquat has a strong destructive effect on green tissue. The liquid should be sprayed evenly on the green stems and leaves of the weeds.
2, light can accelerate the efficacy of paraquat, so in the fine weather, the effect of weed control is very good.
3, the use of paraquat in the garden, should be according to 20% water per acre 150 ~ 200 ml, 50 kg water spray evenly. However, it depends on the growth of weeds. If the weeds are relatively strong, the dosage will increase.
4. Use paraquat in the nursery. Before sowing, the dosage is different after sowing. Before planting, use 20% water agent 75-200 ml per acre, spray 25 kg water, and the growth period after sowing should be 20% water according to the acre. The agent is 100~150 ml, and 50 kg of water is sprayed evenly on the weeds.
5. Orchards, mulberry gardens, tea gardens, rubber gardens and forest belts are used in weeds, which are in a prosperous period. Use 20% water solution per acre 100-200 ml, 25 kg water, evenly spray weed stems and leaves. When the weeds grow to more than 30cm, the dosage should be doubled.
6. Wide-grain crop fields such as corn, sugar cane, and soybean can be pre-treated or post-emergence pre-emergence treatment. In the middle and late stages of crop growth, protective directional spray can also be used to control inter-row weeds. Pre-emergence or post-emergence pre-emergence treatment, using 75-200 ml of 20% water per acre, and spraying 25 kg of water to control the weeds that have been unearthed. In the crop growth period, 100-200 ml of 20% water solution per acre and 25 kg of water are used for protective directional spray between rows.
7. Practical experience shows that paraquat has no obvious effect on Rehmannia.
Note on the use of paraquat:
1. Paraquat is very toxic to humans, so it is necessary to fully take personal protective measures.
2. Spray with paraffin spray or directional spray when spraying paraquat. Do not spray the liquid onto fruit trees or other crops.
3. Paraquat cannot be mixed with pesticides with cations.
4, the spray should be even and thoughtful, can improve adhesion.
I hope that everyone will strictly abide by the use of paraquat herbicide when spraying herbicides , and beware of phytotoxicity.
