The greenhouse vegetable fight drugs are exquisite
Are all kinds of sheds, and some peasants spend twice as much money on drugs as they can't prevent disease. Why? You may wish to take a look at the following content. Before spraying the sprayer and the pipeline, fighting drugs can not be missed spray, re-spray and so everyone is clear. What is the point before fighting drugs, fighting drugs, and fighting drugs?
1. Clearing the sick and sick body The diseased fruit and even the diseased plants are the source of infection. Clearing them out of the shed is to reduce the source of infection and the effect of natural medicine will be better.
2. Choose the date of fight drugs The majority of the farmers are yelling at it, playing drugs once a week or so. However, the prevention of disease is the most important adjustment of environmental conditions, rather than fighting drugs. Some farmers can do not fight drugs for 50 or 60 consecutive days. Only when they fight drugs, do they fight drugs and fight at key points. For example, the day before watering, the day before cloudy days, and the time when the key disease was discovered for the first time. Because you do not fight drugs at this time, it may cause greater losses.
3. The time to choose the time to fight drugs is not certain, but one of the principles is to maintain ventilation when fighting drugs, the second principle is not to fight drugs during high temperature and light hours, such as summer noon. Once I met a farmer, I hadn’t let it go in the morning. The medicine was over and I was not ready to let it go. This does not work. The entire shed is very wet. Adding so much water in the morning, some germs can enter the vegetables within an hour. If you fight in the afternoon, it should be done half an hour or even an hour before the wind is closed to ensure that moisture is removed. Of course, for individual pests, there is a special time requirement to fight drugs is another matter.
4. The choice of drugs If it is to prevent disease, it should be clearly aware that the key to the disease at that time was prevention of diseases, such as tomato gray mold in the winter and spring to focus on prevention, virus disease in the summer and autumn prevention; if it is to cure the drug must be symptomatic You can't guess if you can't guess if you're looking for experts.
5. Dilution times of the drug Pesticide should be used according to the instructions, it can be added slightly, but it is not recommended to double use. If you feel that the efficacy is not good, you can use other medicines first, and second, improve your medicine.
6. The use of protective agents in the compounding of medicines during the disease prevention process. The pesticide of the same composition should not be mixed, and some farmers do not even look at the ingredients of the pesticide. How can we do it well? Macromolecule-type drugs can generally be compounded, and small-molecule drugs should be used with caution, especially alkaline (Leading away, it is also prudent to mix calcium with other fertilizers and pesticides).
7. Drug concentration The total concentration of all drugs and fertilizers should generally not exceed three-thousandths of a millimeter. If it reaches five-thousandths, it is very easy to produce phytotoxicity.
8. Effect of Spraying The best effect of spraying is to “fill†the “small†water spots on the back of the blade. This is determined by the pressure of the sprayer and the speed of travel. It is easy for the water to go slowly. The water point is too thin or not to be reached, and the pressure is small. So when you start the fight, check the effect of the spray.
9. One or two days after the fight, observe the epidemic to determine whether it is necessary to fight the medicine again and fight most pesticides. The continuous use of the same ingredients should not exceed two times.
