I am not certain how many dispensors i could use in scattered , unorganised and  neglected plants of apple plants. I am finding one , 5,10 and a mximum of fifty plants at various places. so no organised orchards. it is sin to kill pests in I that area. I am using the scientific diplomacy to use oheromone traps and dispensors for managing this pest.

May anybody share his experience for the above
