Research on the Green Control Techniques for Sugarcane Borers

Purposes In order to explore and seek high-efficiency and safe green control techniques on sugarcane borers, promote green control of diseases and pests of sugarcane, build a resource-conserving, environmentally friendly and sustainable governance system of diseases and pests of sugarcane.

Methods In 2016, new sex pheromone trap of sugarcane borers, Abamectin·Bacillus thuringiensis (Bt) and tebufenozide were selected and applied in field trials.

Results The use of new sex pheromone trap of sugarcane borers (6 hm^–2) in combination with 0.05% Abamectin·10 billion active gemma/g Bt WP (1.8 kg/hm²) or new sex pheromone trap of sugarcane borers (6 hm^–2) in combination with 200 g/L tebufenozide SC (1.5 L/hm²) were the best in the sugarcane production. New sex pheromone trap of sugarcane borers should be installed in early March, and biological agents were mixed with water 900 kg/hm² and sprayed evenly sugarcane plants at the beginning of April, and the control effect of dead heart rate and bored stalk rate could be more than 69.98% and 49.09% respectively, and it was superior to the control pesticide 3.6% bisultap GR (90 kg/hm²).

Conclusions The new sex pheromone trap of sugarcane borers in combination with Bt or tebufenozide is the optimum mode of green control techniques on sugarcane borers. When it was alternately or coordinately used with other technology, it could delay the emergence and development of drug resistance, and it was worthy of widespread popularization and application in sugarcane area.
