This project sought to develop new approaches to pest control, by means that are sustainable and do not contaminate the environment, specifically through novel approaches to integrated management of pototo pests.
The main objective of this research was to determine the efficacy of new components of integrated management of the Andean potato weevil, Premnotrypes vorax.
Researchers confirmed that application of Triflumuron to alternate rows and to the lower half of the potato plant is sufficient for good control of the Andean potato weevil, thereby eliminating cost and diminishing the use of pesticides. The traps for the eggs by using straws of Stipa is a new contribution to the reduction of damage of the tubers by the Andean potato weevil. This reduces the number of Andean potato weevil capable of damaging the potato tubers.
