How to do the drug damage caused by propiconazole?

What are the symptoms of propiconazole drug damage? What are the characteristics of propiconazole drug damage? What is the cause of drug damage caused by propiconazole? The following land network is briefly introduced for netizens' reference. I. the common symptoms of propiconazole foliar spray are young tissue hardening, brittleness and easy to break. The leaves become thicker and darker. Plant growth retardation (usually does not cause growth stop), dwarfing, tissue necrosis, chlorosis, perforation and so on. Seed treatment can delay seed germination. 2. The characteristics of drug damage of propiconazole there are great differences in tolerance among different crops. In recent years, we have observed the drug damage caused by the use of propiconazole in the seedling or young fruit stage of many kinds of crops, and found that different crops have different tolerance to propiconazole. For example, the tolerable concentration of propiconazole EC (25% propiconazole) to wheat and rice is 800Mel 1000 times, banana 1000Mel 1500 times, tomato and pepper 3000 times, grapes 4000 Mel 5000 times, strawberries 5000 times, watermelons 6000Mel 8000 times. The degree of drug damage is different in different growth periods of crops. Propiconazole is prone to drug damage in seed germination, shoot emergence, seedling extension, flowering and young fruit stage, but rarely in other periods. The losses caused by drug damage are also different in different periods. The influence of seedling stage is small, and the influence of flowering stage and young fruit period is the greatest, most of which will result in yield reduction and quality decline. Third, the causes of propiconazole drug damage 1. Physical and biochemical effects of propiconazole. Propiconazole has certain plant growth regulatory activity. By inhibiting the synthesis of gibberellin, reducing the content of gibberellin and indole acetic acid, eliminating the apical dominance of plants, thickening the stem, dwarfing and compacting plants, and increasing the contents of chlorophyll, protein and nucleic acid. At the same time, propiconazole is only transmitted upward in plants and is stable in plants. The high accumulation of propiconazole can inhibit the respiration of these plant tissues and lead to abnormal crop growth. 2. Unreasonable use of pesticides. Users do not know the concentration of propiconazole in various crops, randomly apply labels to other crops, habitually increase the concentration and do not know the appropriate period for use, are the reasons for the frequent occurrence of propiconazole drug damage accidents. 3. There is not enough research on the application technology of propiconazole in scientific research institutions and agricultural technology extension departments. Enterprises are eager to pursue benefits, and they are widely promoted to the market without in-depth and extensive experiments and demonstrations. 4. control countermeasures of propiconazole drug damage in the early stage of crop growth, if the propiconazole drug damage does not cause large area necrosis, but only causes growth retardation, it can be detoxified by foliar spraying auxin that promotes cell division, and foliar fertilizer is sprayed properly. this has little effect on the yield; increase publicity and improve the awareness of users Production and sales enterprises should carry out a large number of tests and demonstrations in the proposed marketing areas to guide farmers to master safe and effective methods of use. Through training, agricultural technology departments at all levels can guide farmers to correctly master the technology of drug use and improve the level of drug use, which is an important measure to fundamentally prevent the occurrence of drug injury accidents. Propiconazole is easy to cause drug damage in the young tissues of crops, but it is relatively safe in the middle and later stages of crop growth, which is also a period when it is difficult to control diseases such as anthracnose. Propiconazole has strong conduction effect and good germicidal effect. It is an effective measure to reduce disaster and increase income.
