Brief analysis of the method of selecting herbicides in yam field

In recent years, with the increase in the variety of pesticides, the dosage form of pesticides is also increasing, and the demand for herbicides has also attracted people's attention.
The best chemical weeding time in yam field is done before the emergence of the seedlings. Today, Xiaobian introduces several yam herbicides used in different periods to help you better grow yam.
Before planting, combine with the preparation of the whole land with 40% Fluorin EC 100-125 ml per acre, add 40 kg of water spray, mix the soil immediately after spraying, and plant the yam every 7-10 days.
Before planting, use 48% of the amount of 48% dilamide or weeding pass (ie Shi Tianbu, common name dimethyl pentole) 130 ml of water per acre. After planting, the herbicide should be used as soon as possible after planting. Moist to improve the control effect.
After the emergence of the seedlings, the weeds 2-3 leaf stage, 15% per acre, 50-60 ml of water and 30-40 kg of water sprayed.
Disabled 50 days before harvest.
The above are several yam field herbicides recommended by Xiaobian, and different herbicides are used in different periods so that weeds can be controlled to the maximum extent.

Super-low Ash Coal Activated Carbon

coal-based activated carbon for water purification is widely used in the deep purification of drinking water, industrial water and wastewater. Industrial water purification and gas phase adsorption, such as power plant, petrochemical, oil refinery, food and beverage, sugar wine, medicine, electronics, fish, marine and other industries water purification treatment, can effectively absorb the water in the free, sulfur and other organic pollution special The price of the coal-activated carbon filter material, especially the precursor of the Mutant (THM), is to purify the impurity and remove the odor. can also be used for industrial exhaust purification, gas desulfurization, petroleum catalytic reforming, gas separation, pressure swing adsorption, air drying, food preservation, gas masks, media carrier recovery solvent Coal activated carbon, industrial solvent filtration, decolorization, purification and so on.

Use: Used in the purification of drinking water, deodorizing, brewing industry, decoloring of pharmaceutical and chemical products.
