The same medicine, different users, the effect feedback is very different. For example, the use of "stabilizing the enemy", most base users reflect the insecticidal, killing, killing, and even egg-killing effects are excellent, especially blocking the breeding chain of pests is particularly prominent. However, there are also some users who say that the effect is not good. Why is this? After careful combing, we analyze and analyze this more general problem with everyone.
1, water is scientific: hard and soft water points, spring water, well water, some water Mountain Mine mostly hard water, containing multiple minerals, to be decomposed pesticide active ingredients, pesticides dilution effect is poor. The clear pond water, stream water and river water are mostly soft water, with less mineral content and good dilution of pesticides. The same medicine, diluted with different waters, has a very different effect.
2, whether to seize the timing of medication: pests and diseases have their regularity, timely medication, in order to be effective. For example, in addition to refractory weeds, Ruibida must be used at the peak of malignant weed growth. If a small amount of weeds is unearthed or the temperature is below 8 °C, or at a high temperature of 35 °C and above, the chemical pesticides are easily evaporated and lost, which is definitely not effective. In addition, the application of emulsifiable pesticides requires no rain for 24 hours when spraying; the application of contact pesticides requires no rain for 48 hours. The same medicine is used when it is not appropriate, and the effect is very different.
3. Alignment of symptoms: It is common to treat crop diseases as pest control, pest control as disease prevention, and mixed pests and diseases as single pest control. This is actually a diagnosis error, which is unclear and leads to wrong medication. For example, physiological zinc deficiency in citrus is characterized by narrow shoots, yellow leaves, deciduous leaves and dead tops. People often mistakenly treat them as viral diseases, of course, the more severe the cure. In addition, matching symptomatic Pharmacy: Some pesticides have certain pests and weeds good effect, but other pests can not do anything, poor control effect. The same medicine, the use of the wrong symptoms, the use of the effect is very different.
4. Whether it is resistant: The resistance of germs, pests and weeds to pesticides is a practical problem that hinders the full play of pesticides and their potential efficacy. This will also present the problem at the beginning of this article: the same drug, in different crop resistance environments, the results vary widely.
5. Whether it is aimed at the target: the occurrence of pests and diseases and the habitat of pests, there is a harmful part on the crop. This particular part is the "target" that the "arrow" that we use should be shot. The target pesticide is not effective. If you use Aiqiu to control the scales, only the spray on the boarding area of ​​the worms is very effective. The same medicine is used for the target, and the effect is very different.
6. Is it preferable to spray instruments: new tools and technologies such as mist and electrostatic spray, which can greatly improve the use efficiency of pesticides, solve poor control effects, and reduce pesticide waste. The same medicine, with different spray equipment, the effect is very different.
