Everyone knows that in the management of agricultural production, various fungicides, insecticides and various herbicides are indispensable, but in actual operation, it may be due to improper use of pesticides during compounding or compounding. This can easily cause phytotoxicity.
Some farmers' friends can't make up the measures in the first time when they find the phytotoxicity, so the damage caused is also huge. The lighter will reduce the output, and the heavy ones may be out of production. So how can farmers' remedies be remedy once crops are devastated? Today, I will share a few tips for farmers' growers, hoping to help farmers.
Spray water
If this situation is caused by the phytotoxicity caused by the sprayed liquid of the leaves and plants, if it is found in time that the liquid has not completely penetrated into the plant, the infected plants can be quickly sprayed with a large amount of water for 2 to 3 times, as far as possible. The washing of the drug on the surface of the plant can well alleviate the continuous development of the phytotoxicity. At the same time, it is recommended that everyone add 0.2% alkali surface in the sprayed water. Since most pesticides are acidic at present, neutralization reactions will occur in the presence of alkaline substances, which will reduce the efficacy of the drug, thus speeding up the decomposition of the drug and reducing the crop. The phytotoxicity.
2. Gibberellin plus white sugar detoxification
For those who have already caused phytotoxicity, the crops have yellow smear, atrophy and other symptoms of phytotoxicity, and our farmers’ friends should detoxify the more affected crops in time. For example, corn and peanuts are over-suppressed due to excessive concentration of paclobutrazol, and growth is stagnant. We can spray gibberellin and white sugar solution in time to quickly restore normal crop growth. Grapes, apples due to copper preparations, Bordeaux mixture caused by phytotoxicity, we can spray 0.5% lime water for relief, to reduce damage to crops caused by phytotoxicity.
3. Herbicide phytotoxicity
Compared with the phytotoxicity of insecticides, herbicides are the most difficult to alleviate. It is found that timely or low levels of phytotoxicity can also reduce losses. If it is not timely or the degree of phytotoxicity is high, it is difficult to restore normal crops. Growing. If it is found that the crop has herbicide phytotoxicity, it is recommended that you spray gibberellin + indole acetic acid + brassinolide, and dilute 500~600 times for spraying. Continuous spraying for 2~3 times can relieve, rejuvenate and immunize. Effect. There is now a plant growth regulator called Bibao that combines the above three types and the effect is the same.
White sugar or brown sugar can improve the efficacy of the crops in terms of controlling the phytotoxicity of crops, and enhance the control effect. The common use of washing powder, salt and alkali-like pesticides can significantly improve the efficacy and stability of pesticides, and the sugar is rich in various kinds. Amino acids are more conducive to disease prevention. The combination of white sugar and Bordeaux mixture can significantly improve the stability of Bordeaux mixture, prevent and cure grape downy mildew, and add a little brown sugar to anthrax can significantly improve the efficacy and improve the commercialization of crops.
The above is the sharing of techniques for medicinal damage in crops. What do you think about the application of sugar in agricultural production? Or if you have any small tricks, welcome to share your comments in the comments section.
Medical protective clothing refers to the protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
