1. Choose the pesticide accroding to your needs

According to the control object, crop variety and different growth stage, select the appropriate pesticide, type of formulation and doseage to achieve the best control effect. About the diseases , pests and weeds during the production, we shouldn’t use the pesticide through our feelings, that can avoid misjudgment, resulting in unsatisfactory effect.  

2. Decide when to use the pesticides scientifically

Applying pesticides too early or too late will not only fail to achieve the purpose of prevention and control, but also increase the cost and pollute the environment. It is necessary to fully investigate the occurrence, harm and development law of the disease, insect pests and weeds before using the pesticides, and use the pesticides accurately and pertinently at the best time of prevention and control, so as to ensure a better prevention and control effect.

3.Formulate pesticide ratio accurately

Low pesticide concentration, small dosage, no obvious control effect, high concentration, large dosage, not only waste of pesticides, but also easy to crop damage, induce resistance to pests and diseases. Pesticide application shall be carried out according to the pesticide application instructions specifically, and the concentration and frequency of precise application shall be targeted to different diseases and insect pests.

4.Timely replacement of advanced application equipment

It is advisable to choose the type instruments with high pressure, fine spray, time-saving and labor-saving. After spraying the agent on the leaf surface, it will form a uniform water film with no large or small spots as the best. Timely replace the old knapsack or stretcher-type application equipment, or the application equipment with poor spray quality, uneven atomization, poor liquid adhesion of pesticide ‘running leakage’, and blocked pipe of the instruments.

5. Improve spray technology

Find the harmful parts of diseases and insect pests, and focus on spraying. General contact pesticides, spray hit the damage site accurately. Internal suction pesticide requiring uniform distribution of droplet distribution on target. For example, it is better to spray the liquid evenly on the back of the leaf (contact) or the front of the leaf (suction).

6. Scientific alternating pesticide, do not mix pesticide

Before pesticide mixing, it is necessary to understand the nature, function and object of control of all kinds of pesticides, mix pesticides scientifically and rationally, so as to improve the control effect, avoid or delay the emergence of resistance of harmful organisms, and save cost. The mixed pesticide is easy to cause pesticide degradation and drug damage. Remember that the mixture of drugs should be ‘ready to use’.

7. Pay attention to the influence of environmental factors

Temperature, humidity, light, rain, wind, soil properties and other environmental factors directly affect the physiological activities of pests and diseases and the performance of pesticides, and the results will affect the efficacy of pesticides. For example, the herbicide acetochlor and  trifluralin with the same dosage have poor weeding effect in drought, but high weeding effect under appropriate soil moisture conditions. Therefore, before the use of pesticides, it is necessary to grasp its performance characteristics, biological characteristics of the control object. In the application process, make full use of all favorable factors, control adverse factors, in order to achieve the best control effect.

8. It's better to fill the formulation with soft water

It is wrong to take water to make a prescription randomly. It is better to use soft water to dilute the pesticide. If hard water is used, the efficacy will be greatly reduced, the calcium and magnesium ions in hard water will react with the emulsion in the emulsion to form calcium and magnesium sediments, destroy the emulsifying performance of the emulsion, reduce the suspension rate of the wetting agent, which is not only easy to crop damage, but also easy to plug the spray nozzle.
