Tests in two southern California counties resulted in similar data offering further proof of the value of soil fumigation for strawberry production. Yield increases as high as 85 per cent were reported following soil treatment. Control of plant pathogens was excellent with full-coverage injections of a mixture of 2 parts of methyl bromide and 1 part chloropicrin applied at 225 pounds per acre.
