Herbicide products are pesticide products that farmers like to use for weed control in farmland; however, when the herbicides are used improperly, phytotoxicity will occur. Therefore, it is very important to use herbicides correctly. The following is a brief explanation of how to correct the pesticides in China. Use a herbicide.
4 major considerations for the use of herbicide products
First, find out the types of weeds and choose the appropriate herbicide variety.
When chemical weeding is carried out, it is necessary to clarify the farmland seedlings and grass conditions, and choose the medicine according to the type and distribution of weeds.
Second, according to local conditions, rational use of drugs.
With a suitable herbicide variety, it can be said that the control effect has reached 50%. However, if it is not properly applied, it is difficult to achieve the desired control effect, and even the phytotoxicity such as corn chemical weeding after the three-leaf period, the nozzle of the sprayer should be lower than the height of the bell mouth to prevent the liquid from being sprayed onto the bell mouth. Within the heart of the heart. In addition, you should pay attention to the weather when applying the medicine. Generally, it is required to apply the medicine on a windless day. When applying under drought conditions, the amount of water should be increased or applied after watering.
Third, master the rational use of technology should be based on the growth period of crops and weeds and the characteristics of the drug to determine the best use period;
The optimal dosage is determined according to the density and type of weeds, as well as the environmental conditions such as meteorology and soil conditions; the corresponding application method is selected according to the type of herbicide. It is worth noting that soil type, soil organic matter content and soil moisture have a great influence on the dose of herbicide for soil treatment. It is generally applied according to the label or the recommended method of use.
Fourth, master the scientific method of dilution of herbicides according to the formulation of the dilution method. The dosage form is different and the dilution method is different.
Finally, the Chinese pesticide network reminds: when using herbicides, pay attention to the drip drifting sputum, the management of fertilizer and water before and after application, the mixing and use of brain surfactants, and the phytotoxicity of the crops.
