The results showed that 30% Tiange multifunctional pesticide-fertilizer could effectively suppress some pests such as sugarcane borer,thrip,aphid and cockchafer. 90 d after pesticide-fertilizer application,the sugarcane withered heart rate was 1. 55% and 2. 55% in the two test points,respectively,significantly lower than the rate of 15. 40% and 19. 40% under control. Before harvest,the sugarcane borer damage rate in the two test points under pesticide-fertilizer treatment was 8. 70% and 9. 47%,respectively,significantly lower than the rate of 34. 50% and 33. 50% under control,and the sugarcane yield was 21. 16% and 22. 14% higher than under control,respectively. 30% Tiange multifunctional pesticide-fertilizer had nutritional and insecticidal effect,which could help to achieve sugarcane pesticide-fertilizer integration and save labor and costs.展开更多
