The insects learn, my dear. Just like how children master a game, pests develop resistance when we use the same "medicine" on them again and again. In our labs, I see this through the microscope—the few survivors pass on their strength. That is why we must be like nature, clever and changing. We are now making sprays from neem and other plants, so the pests cannot learn so easily. *Bhagirathi garuvu cheyaku, manaki telisina danini marchali* — do not rely only on the familiar river, we must also learn new paths.
