How to improve the use of pesticides
In order to enhance the effective use of **pesticides**, some farmers and their friends tend to increase the amount of chemicals applied. As the saying goes, “If you're not afraid of a bull, you won't be afraid to add two pounds of charcoal.†However, this is only necessary when pests develop resistance. The issue of drug resistance requires careful analysis of specific agents and cannot be generalized. To ensure efficiency, safety, reduce environmental pollution, and delay the development of resistance, I suggest the following five key points. Among them, accurate diagnosis, proper selection of pesticides, and strengthening predictive capabilities are essential for improving pesticide usage:
First, accurate diagnosis and appropriate treatment. Correct identification of the pest or disease is crucial for success. Only with an accurate diagnosis can we determine the right strategy and choose the most suitable pesticide. At the same time, it's important to understand the properties and target organisms of different chemicals to ensure they are used effectively.
Second, strengthen early warnings and apply pesticides at the right time. Pests and diseases follow a certain pattern of outbreak, much like a fire that must be controlled before it spreads. Once an infestation becomes widespread, it becomes a "post-horse" situation—too late to act effectively. Moreover, all pesticides have a limited window of effectiveness. Timely application is essential to ensure the treatment works as intended. This requires regular monitoring of crop conditions, pest populations, and good forecasting practices.
Third, choose the right equipment to improve efficiency and quality. Many **fungicides** mainly serve a protective function, while many insecticides rely on stomach toxicity or contact killing. For these, even distribution of the chemical is vital—no over-application, no leakage. In large-scale operations, it’s especially important to continuously improve application techniques and increase mechanization to ensure timely and effective control.
Fourth, precise dosing and proper application. Accurate dosage is the foundation of effective treatment. If the dose is incorrect, the results will be unsatisfactory. A common mistake in practice is either increasing the dose unnecessarily or using too little water, which reduces the effectiveness of the treatment.
Finally, delay resistance by rotating or mixing products. Resistance has become a major challenge in agricultural production. It is a direct result of long-term, large-scale use of a single pesticide. By rotating or combining different types of insecticides and bactericides, we can prevent pests from developing a stable resistance mechanism, thereby delaying the onset of resistance. This not only improves the effectiveness of pest control but also helps preserve our pesticide resources for the future.
