FOR USE ON GRAPES
DIRECTIONS FOR USE
IT IS CRITICAL THAT ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE BE APPLIED AS DIRECTED.
Growers using this product must maintain careful records of damage within their vineyard. Careful monitoring of adult populations is essential since the use of ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE is dramatically different from traditional broadspectrum insecticides registered for grape berry moth control.
Designing successful programs with ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE depends on ongoing discussion with IPM specialists, extension horticulturists and company representatives.
NOTE: ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE reduces mating of grape berry moth. However, if a major source of mated female moths of this species is present adjacent to the treated vineyard, migration of these moths may significantly reduce the level of control achieved. Sources are likely to be unsprayed vineyards or wild grape vines within 300 metres of treated field. This can be overcome by:
- Treatment of entire blocks and not just sections of large conventionally treated vineyards, which frequently serve as sources of mated females.
- Treatment of infestation sources with ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE.
- Treatment of edges of pheromone-treated vineyard with timely insecticide applications.
Supplementary applications of insecticide are advised when ISOMATE-GBM PLUS GRAPE BERRY MOTH PHEROMONE is used to control high populations of gape berry moth. All pests must be monitored so that timely intervention with conventional insecticides is possible.
FOR USE ON GRAPES
RATE: 500-1000 dispensers per hectare (200-400 dispensers per acre). 1000 dispensers per hectare must be applied to high-risk vineyards, i.e. any vineyard adjacent to unsprayed vineyards or within 300 metres of wild grapes.
APPLICATION: Attach dispensers onto upper training wire of vines. One application per season should be sufficient. Applicator should wear gloves on hands when making application.
TIMING: Apply prior to moth emergence in the spring. Dispensers release pheromone for up to 150 days depending on temperature. Consult your local extension specialist or certified crop advisors for proper timing.
