The Strawberry Root Weevil (Brachyrinus ovatus L.) is the most serious pest of strawberries on the Pacific Coast. The history of past efforts to arrive at a satisfactory method of control is reviewed. Previous methods suggested by different workers have been cultural methods, including suitable crop rotation and the use of weevil proof barriers. The most recent method is by the use of poisoned bait, consisting of chopped evaporated apple waste. The poisons used may be Sodium fluosilicate, Magnesium arsenate, Calcium arsenate, and Sodium fluoride. All these have been found effective but in the experimental work at Victoria, Sodium fluosilicate was found the most satisfactory. Apple waste containing approximately 20 per cent moisture was found more attractive than super dried bait and Sodium fluosilicate was found the most suitable poison to use with waste containing that degree of moisture. A strength of 5 per cent of poison was found to give the best results. Two applications of the bait are recommended, the first in April and the second in June.
