There are many kinds of pesticides . Only when they are familiar with pesticides can they be used rationally; only by mastering the main points will the control effect be improved.
Need to pay attention to the use of pesticides: understand the performance, characteristics, control objects and scope of use of pesticides, timely symptomatic medication, appropriate amount of pesticides, pay attention to the number of pesticides sprayed, but also pay attention to pesticides should be appropriate.
Today, the China Pesticide Network focuses on the “Classification of Pesticide Application Rangesâ€.
Classification of pesticide application range
1. Full application of the whole field is uniform and uniform spraying, including weeds and crops. This applies to the case where highly selective herbicides and weeds are weeded in crops that are common throughout the field and are dense.
2, the strip application of the drug solution in a limited range, the use of fan-shaped nozzles, such as about 5cm of the crop planting belt spray treatment to eliminate inter-plant weeds on the crop belt, for the seed belt The field weeds are intercropped or artificially assisted. Strip spray can save one-half to two-thirds or more of the dose, but requires more sprayer attachments and reduces the amount of work by about 15%.
3, point-like application of medicinal treatment to treat a limited area, such as grass or as a crop after the full spray treatment, local re-spraying or the distribution of weeds in the core (such as perennial weeds such as fragrant aconite). This method is highly targeted and economical.
4. Directional spray control spray direction of the liquid, apply to weeds or ground, and try not to touch the crop as much as possible. This is a protective spray for post-emergence crop treatment with some of its biocide or contact herbicides.
