Correlation analysis of pesticide registration and pesticide reduction
In this paper,the pesticide information on China pesticide information website was searched and analyzed.The results showed that:the current pesticide registration data varied greatly among different crops,mainly concentrated on large-area cultivated crops such as rice and wheat,but few pesticide varieties were registered on some small crops with local characteristics.Choosing different pesticides and dosage forms in prevention and treatment can effectively reduce the amount of pesticides used.Taking rice bacterial blight with more registered pesticide data as an example,the recommended dosage of thifluzamide is lower than that of azoxystrobin and far lower than that of jinggangmycin and other fungicides with large dosage.The use of thifluzamide and azoxystrobin mixture did not reduce the amount of pesticides per unit area,but the amount of active ingredients used in the mixture was lower than that used in the single agent alone.Scientific selection and registration of pesticides may be an important way to carry out the work of reducing pesticide quantity and increasing pesticide efficiency.
