Application of herbicide three attention

First, correctly master the period and dosage of the drug: Some herbicides are mainly soil treatment, and some are sprayed with stems, leaves and plants. It is necessary to use the medicine according to the type of weed in the orchard at the most appropriate time. Most of the herbicide dose is calculated on the basis of the active ingredient, unlike other pesticides, which are clearly indicated how many times the application is applied. Therefore, you need to test and apply it yourself in order to prevent weeds in a timely and effective manner.
Second, strict operating procedures: read the instructions and precautions when using. In addition to the purpose of mixing the two herbicides for synergy, do not mix them together. It is best to use special spray equipment when spraying to prevent spraying other herbicides after spraying the herbicide, causing phytotoxicity due to residual herbicides. Pay attention to evenness when spraying, and do not spray the medicine on the branches and leaves of the fruit. When using, choose a spray when there is no wind on sunny days. Some herbicides have corrosive effects on metal containers such as iron (such as glyphosate). Plastic or ceramic containers should be used.
Third, pay attention to labor protection: wear overalls, wear masks, gloves and glasses during handling, preparation and spraying. In case of contact with the skin, rinse immediately with water. If there are symptoms of pesticide poisoning during operation, stop working immediately and go to the hospital for treatment to prevent accidents.
Measures to Avoid Drug Resistance With the continuous use of pesticides on fruit trees, pests are more and more susceptible to drug resistance, which affects the normal growth of fruit trees. We should take various measures to avoid the resistance of pests.
1. Comprehensive prevention and control: In the process of controlling pests, it is necessary to overcome the tendency of relying solely on chemical pesticides, and should advocate comprehensive prevention and control measures such as agriculture, physics and biology, and cooperate with each other to learn from each other.
2. Rotational medication: Do not use a single variety of agents for a long time to cut off the formation of resistant populations in the biota. Rotational medication should try to use different agents with different mechanisms of action, such as the use of organophosphorus preparations, pyrethroid preparations, and carbamate preparations; endogenous fungicides are easy to cause drug resistance, and should be substituted with arsenic, inorganic sulfur, and copper. Rotate use; stone sulfur mixture does not produce resistance to pests.
3, mixed medication: the combination of two different modes of action and mechanism can also slow the occurrence of drug resistance, such as the combination of toxic mycelium and mancozeb, organic phosphorus preparation mixed with pyrethroids.
4, the use of synergists: synergists can inhibit the insecticide decomposition enzyme activity of compounds in the pests, can improve the efficacy, such as harm Liping, save money, multi-functional plant synergists.
5. After a pesticide has caused drug resistance, the phenomenon of stopping the use of drug resistance within a certain period of time may gradually decrease.
6. Use the correct application technique to evenly distribute the pesticide on the plant.
