Reduce the source of pests and diseases: clean up diseased leaves, diseased branches, diseased fruits and even diseased plants (the source of infection of most diseases), take out the incineration treatment outside the field, and the effect of fighting drugs will naturally be better.
Choose the time to fight
(1) Determine according to temperature changes: whether it is a plant or an insect or a pathogen, 20 to 30 ° C, especially 25 ° C, is the most suitable activity temperature. At this time, it is more effective to fight the pests and diseases in the active period and to make the crops safer. In the summer hot season, the time of fight should be before 10 am and after 4 pm. Spring and autumn cool season, should be selected before 10 o'clock in the morning before 2 o'clock in the afternoon. In the greenhouse in winter and spring, it is best to choose to fight in the morning in sunny weather.
(2) According to the change of humidity, the liquid medicine will be affected by many aspects from the deposition of pests and diseases to the unfolding of the uniform film, and the humidity of the air will be greatly affected.
When the humidity of the air is too high, the deposited liquid will become a larger droplet, and after being affected by gravity twice, it will deposit on the lower part of the plant, thereby causing phytotoxicity. When the humidity of the air is too small, the liquid easily evaporates, resulting in less exposure to the target, thereby reducing the efficacy, and severe burning lesions. Therefore, the fight drug environment should be kept ventilated.
(3) According to the characteristics of pests and diseases: such as prevention and control of whitefly (flying away when touched), when the morning dew is not dry, fight drugs; control flowers and horses, fight in the morning when the flowers are blooming; Fight drugs in the evening or at night. Such as prevention and treatment of diseases, after the rain before the rain, before the watering, before the cloudy days, at the beginning of the disease, etc. (because many diseases mainly rely on running water, wind and rain to spread, at this time do not fight drugs, sick and crying is too late).
Dilute pesticides should be appropriate: use the medicine according to the instructions to dilute the use, depending on the severity of the occurrence of pests and diseases can be slightly increased, but it is not recommended to double use. If you feel that the drug is not effective, you can rotate the pesticide of another mechanism on the one hand, and optimize your own drug-making technology on the other hand.
It is reasonable to mix pesticides: in the early stage of the disease, a therapeutic fungicide is absorbed by a protective fungicide. In the case of insecticide, it is optional to use an insecticide which has an ovicidal action and an insecticidal action. Note: The same ingredient should avoid mixing, and the copper preparation should avoid mixing with alkaline pesticides to prevent phytotoxicity.
When fighting drugs
Master the method of fighting drugs: For pests and diseases that like to be harmed in a certain part of the plant, focus on this part (such as leaf back, fruit, flower, stem base, etc.).
Grasp the distance and speed of the fight: After the liquid is sprayed from the nozzle, it collides with the air and breaks into smaller droplets. The result is that the droplets become smaller and smaller. That is to say, the farther away from the nozzle, the smaller the droplet is within a certain distance. Small droplets are easier to deposit and spread on the target. Therefore, it does not mean that the nozzle is more closely attached to the plant. In general, the spray head of the knapsack electric sprayer should be kept at a distance of 30 to 50 cm from the target, and the motorized sprayer should be kept at a distance of about 1 m.
Adjust the size of the drop: According to the performance of the sprayer and its nozzle, adjust the appropriate droplet size. In the greenhouse vegetables to control diseases and aphids, whitefly and other tiny pests, you can choose a fog machine; when the open field vegetables to control pests and diseases, you must choose to spray a larger sprayer.
In short, it is irrational to hope that the "special effects medicine" is irrational. The "medicine to the disease" is also a problem. In order to improve the efficacy, it is necessary to find the limit effect from the above points. The only way to eliminate the unfavorable factors is to make the pesticide's efficacy work better.
Refinement of Copper removing agent and Decoppering Agent through Lead Fire Process
