The red period refers to the beginning of the apple center flower buds, which are initially in the early stages of separation, usually in the middle or late April. This is the critical period for pest control. However, in recent years, there have been many phenomena where the red period does not fight drugs, or dry sticks are red and white, but these practices are correct? Do not fight drugs during the red period The answer is no. Because pests have begun to move and are not resistant at this time, spraying water saves money and saves money. At this time, the temperature is not stable, and when the temperature rises rapidly, it drops rapidly, causing "cold spring" effects on fruit setting. Spraying foliar nutrition with Luhong period medicine can effectively prevent the harm caused by "cold spring". Is it possible to combine dry sticks and dew red twice? The answer is no. Because of different control purposes, stem branch medications are mainly directed at rot disease, rough bark ring disease, zinc deficiency lobular disease, and alfalfa weeds, etc.; drugs used during the red period of buds are mainly for mycotic disease, brown spot disease, powdery mildew, and apple leaf roller , Starscream, Aphids, and leaf miners. The use of different types of drugs: dry sticks use more emulsifiable concentrates to enhance adhesion, more use of liquid red lotion to prevent injury. Spraying methods are different: Dry branch spraying uses water-washed whole tree spray, the dilution multiple is small, and the medication is stable and accurate. The concentration of the drug in the red period should not be too large, and it must be floated from the tree body at a certain distance when spraying. Inappropriate medication period: the synthesis must be administered in the middle of April. At this time, it is not possible to eradicate overwintering pathogenic bacteria with high-concentration medicaments, and it is too long from the floral red period, thus wasting human and material resources without much effect. How to rationally use drugs during the red period Spraying should avoid windy, cold, and hot weather. It is best to use it from 10:00 am to 23:00 pm. The concentration of the drug should not be too large. Keep a certain distance from the tree body when spraying. Prevent spraying at the same time as even spraying. Especially do not sweep the spray bar back and forth. The fungicide is recommended to use the safest components such as Difenoconazole, Polyoxine, and Zhongshengmycin. Insecticides are recommended to choose ingredients that do not harm the wall bees such as triflumuron, methacrylate, and high chloride. Formulations should choose safe formulations such as water, micro-emulsions and water dispersible granules. Be cautious with fluorosilazole and other active triazole bactericides and xylene auxiliaries chlorpyrifos (vegetable oil additives, such as Anminol, original imported products, additives used coconut oil), to avoid the occurrence of phytotoxicity in special weather . In the red period medication, foliar nutrition and growth regulators should be strengthened to prevent “cold springâ€. Luhong period is the key period for the orchard to control pests and diseases. Only reasonable use of drugs can make full use of orchards in the management of orchards throughout the year, laying a good foundation for the high yield and quality of orchards.
