    Herbicide damage refers to a series of abnormal phenomena caused by the inappropriate application of herbicides and the stunting of the normal physiological function or growth and development of crops. Acute drug damage has obvious symptoms in a few hours to 3 4 days after spraying, and it develops rapidly, such as burns, perforations, wilting, falling leaves, falling flowers, falling fruits, etc. Chronic pesticide damage caused obvious reactions after spraying for a long time, showing poor growth, leaf deformity, greening and yellowing, delayed ripening, poor flavor, and dissatisfied grains.

    The specific drug to relieve herbicide damage is brassin.

    Brassin is a non-selective herbicide, which means it has a killing effect on most plants, not just target weeds. Therefore, special care needs to be taken when using brassinin to avoid damaging non-target plants. Brassin is a systemic herbicide that kills various parts of the plant, including the leaves, stems, and roots, by moving throughout the plant after being absorbed by the plant.

    Brassin is considered to be a highly effective herbicide with good herbicide effect on many common weeds and plants. It is commonly used in fields such as agriculture, horticulture, forestry, and landscape management. When using brassin, proper guidelines for use and safety measures should be followed.

    This includes proper formulation and concentration, proper application timing and method, avoiding splashing on non-target plants or water sources, etc.

    Precautions for pesticide use

    Before using any pesticides, carefully read and follow the instructions and recommendations on the product label. Labels often provide critical information such as proper usage, safety precautions, protective gear, and storage requirements. Use the correct local pesticide dosage and concentration and do not exceed the recommended dosage.

    Overuse can lead to pesticide damage, residue problems, and environmental contamination. Choose the right weather and growing stage for pesticide spraying.

    Avoid using pesticides in adverse conditions such as strong winds, high temperatures or rainfall to reduce the risk of pesticide loss and scattering. When using pesticides, wear appropriate protective equipment such as gloves, masks, goggles, and protective clothing. Avoid contact with pesticides**, eyes, nose and mouth, ensure adequate ventilation and avoid contamination of water sources and non-target plants.

    When storing pesticides, store them in a safe, dry, well-ventilated place, away from children and animals, according to the instructions on the label.

    What are the symptoms of crop damage caused by herbicides? Plant growth regulators: Crops are affected by hormonal herbicides, methyl chloride and chlorpyrifos.

    Cultures are mostly yellow leaves and white burn spots. Since dimentethone is a contact herbicide without inhalation TEM, the crop can slowly grow new leaves within about a week after a slight damage to the drug and gradually resume growth, influencing and causing damage to the drug by tarong, or damage caused by inhalation of a conductive herbicide and manifestations of damage caused by the previous crop herbicide: from the plant's point of view, first, the plant detects that the nucleus begins to deform and the growing point of the crop begins to turn.

    The brown leaves lose their yellow, green, and vertical, and the new heart leaves are usually purple or yellow, curved longitudinally! For example, strengthen the management of oxazole paddy fields and sprinkle enough water to promote the absorption of a large amount of water by maize roots, so as to reduce the concentration of herbicides on plants, reduce the damage caused by drugs, appropriately increase the depth and frequency of exchanges, improve soil aeration, and promote the application of herbicide residues in crops.

    Leaf spot symptoms caused by chemical fertilizers are similar to those caused by contact herbicide deficiencies, pollution and overfertilization, especially nutrient, sulphur dioxide, ozone, C12 and other pollution, as well as herbicide deficiencies, which can form white spots on the leaves of harmful plants, which turn brown quickly after locust clearing. This is the damage caused by damaging herbicides. Leaf tissue (spray of stems and leaves after sowing) or white fig pieces and small white spots at the base of the leaf veins of the average brown fig.

    Substances that are harmful to cell membranes, such as burning weeds, can turn yellow on the newly grown leaves of cereals and herbaceous plants, rot at the base of the leaves, and then turn yellow on the old leaves.

    It is a regulator of the growth of grass herbs (e.g., Najiajing, Jinghua, Jingyin, Gecanon, etc.), selectively killing large-leaved weeds, but they can also disrupt the growth of grasses and broad-leaved plants. Obvious defects may occur in roots, stems, leaves, flowers, and ears, and the typical symptom of damage caused by long-term use of herbicides is deformity; If the onion leaves shrink and the stems and petioles bend, it is difficult to drive, the symptoms of pesticide damage persist for a long time, are affected in the early stages of crop growth and remain in the final stages.

    The first is that the leaves are yellow, and the second is that when the rice is growing, the development is abnormal, it does not head when it should be headed, and it cannot bloom when it should bloom, and the growth is slow.

    It can be judged by the composition of the herbicide, by the efficacy of the herbicide, and by the way the herbicide is used.

Washing method. When the dosage of systemic herbicides such as herbicides is too large and causes pesticide damage, it should be immediately rinsed with water or sprayed to wash off the unabsorbed liquid on the crop and reduce the continued harm of the residual liquid to the crop. Generally, after washing 3 times, the town sees new leaves, and the lost green leaves begin to color, and the town recovers in 7 to 10 days.
