Factory Price Agricultural Chemicals Herbicides Weedicide Weed Killer Pendimethalin 33% EC; 330 G/L EC

Introduction

Mode of Action

Pendimethalin is a dinitrotoluidine herbicide. It mainly inhibits meristem cell division and does not affect the germination of weed seeds. Instead, it is absorbed by the buds, stems and roots during the germination process of weed seeds. It works. The absorption part of dicotyledonous plants is the hypocotyl, and the absorption part of monocotyledonous plants is the young buds. The damage symptom is that the young buds and secondary roots are inhibited to achieve the purpose of weeding.

Active weed:

Control annual grasses and broad-leaf weeds such as crabgrass, foxtail grass, bluegrass, wheatgrass, goosegrass, gray thorn, snakehead, nightshade, pigweed, amaranth and other annual grasses and broadleaf weeds. It also has a strong inhibitory effect on the growth of dodder seedlings. Pendimethalin can effectively inhibit the occurrence of axillary buds in tobacco, increase the yield and improve the quality of tobacco leaves.

Suitable crops:

Corn, soybeans, cotton, vegetables and orchards.

Other dosage forms

33%EC，34%EC，330G/LEC，20%SC，35%SC，40SC，95%TC，97%TC，98%TC

Using Method

1. Soybean fields: Soil treatment before sowing. Since the drug has strong adsorption, low volatility and is not easy to photodegrade, mixing the soil after application will have little effect on the weeding effect. However, if there is a long-term drought and the soil moisture content is low, it is appropriate to mix 3 to 5 centimeters to improve the weeding effect. Use 200-300 ml of 33% pendimethalin EC per acre and spray the soil with 25-40 kg of water before soybean planting. If the soil organic matter content is high and the soil viscosity is high, the dosage of pesticides can be appropriately increased. This drug can also be used for pre-emergence treatment after soybean sowing, but it must be applied within 5 days after soybean sowing and before emergence. In fields with mixed monocotyledonous and dicotyledonous weeds, it can be used in conjunction with Bentazone.
2. Corn field: It can be used before and after emergence. If it is applied before emergence, it must be applied within 5 days after corn is sown and before emergence. Use 200 ml of 33% pendimethalin EC per acre, and mix it evenly with 25 to 50 kg of water. spray. If the soil moisture content is low during pesticide application, the soil can be lightly mixed, but the pesticide should not come into contact with the corn seeds. If pesticides are applied after corn seedlings, it should be done before broadleaf weeds grow 2 true leaves and gramineous weeds reach 1.5 leaf stage. The dosage and application method are the same as above. Pendimethalin can be mixed with atrazine to improve the effect of controlling dicotyledonous weeds. The mixed dosage is 200 ml of 33% pendimethalin EC and 83 ml of 40% atrazine suspension per acre.
3. Peanut field: It can be used for soil treatment before sowing or after sowing. Use 200-300 ml of 33% pendimethalin EC per acre (66-99 grams of active ingredient) and spray 25-40 kg of water.
4. Cotton fields: The pesticide application period, method and dosage are the same as those for peanut fields. Pendimethalin can be mixed or used in combination with fulon to control difficult-to-control weeds. Pendimethalin can be used before sowing, and volturon can be used for treatment in the seedling stage, or a mixture of pendimethalin and volturon can be used before emergence, and the dosage of each is half of that of the single application (the active ingredient of volturon alone is 66.7~ 133.3 g/mu), use 100-150 ml each of 33% pendimethalin EC and fulfuron per mu, and spray 25-50 kg of water evenly.
5. Vegetable plots: For direct-seeded vegetable plots such as leeks, shallots, cabbage, cauliflower, and soybean sprouts, they can be watered after sowing and applying pesticides. Use 100 to 150 ml of 33% pendimethalin EC per acre and 25 to 40 ml of water. Kilogram spray, the medicine lasts for about 45 days. For direct-seeded vegetables with a long growth period, such as seedling leeks, the pesticide can be applied again 40 to 45 days after the first application, which can basically control the weed damage of the vegetables throughout the growth period. Transplanted vegetable fields: Cabbage, cabbage, lettuce, eggplant, tomato, green pepper and other vegetables can be sprayed before transplanting or after transplanting to slow down the seedlings. Use 100~200 ml of 33% pendimethalin EC per acre. Spray 30~50kg of water.
6. Tobacco field: The pesticide can be applied after the tobacco is transplanted. Use 100~200 ml of 33% pendimethalin EC per acre and spray evenly on 30~50 kg of water. In addition, it can be used as a tobacco sprout inhibitor, which is beneficial to improving the yield and quality of tobacco.
7. Sugar cane field: The pesticide can be applied after the sugar cane is planted. Use 200~300 ml of 33% pendimethalin EC per acre and spray evenly on 30~50 kg of water.
8. Orchard: During the growing season of fruit trees, before weeds emerge, use 200-300 ml of 33% pendimethalin EC per acre and 50-75 kg of water for soil treatment. To expand the herbicidal spectrum, it can be mixed with atrazine.

Precautions

1. Pendimethalin is highly toxic to fish, so use it with caution and do not pollute water sources and fish ponds.
2. When applying pesticides to corn and soybean fields, the sowing depth should be 3 to 6 centimeters and covered with soil to prevent the seeds from contacting the pesticides.
3. When treating soil, apply pesticides first and then irrigate, which can increase soil adsorption of pesticides and reduce pesticide damage. In fields with many dicotyledonous weeds, mixing with other herbicides should be considered.
4. On sandy soil with low organic matter content, it is not suitable to apply before emergence.
