Control of mealybugs and scale on pineapples by methyl bromide fumigation of planting material


, : Control of mealybugs and scale on pineapples by methyl bromide fumigation of planting material. Phytophylactica 19(3): 255-258

Pineapple mealybugs, Dysmicoccus, brevipes and Pseudococcus longispinus, as well as pineapple scale, Diaspis bromeliae, were effectively controlled on Cayenne and Queen pineapple plants by methyl bromide fumigation of planting material at 32 or 40 g m-3 at 22.7 to 34.6.degree. C and 20 to 25.degree. C, respectively, for 2 to 8 h. Some degree of phytotoxicity occurred with exposures of 4 h and longer, but this was only statistically significant under the 8 h fumigation.
