For example, this year there are a number of colored traps in place to 

 test the effectiveness of various colors in monitoring tarnished plant bug 

 populations. Fungicides will be applied according to flowering and berry 

 development, while Botrytis (the primary berry rot fungus) will be monitored on 

 last year's leaves and the developing flowers and fruit. Similar monitoring 

 will be done in non-IPM plots. It will also be possible to test the validity 

 of a new gray mold model (1). Weed species and numbers will be evaluated in 

 plots, and the herbicide practices of growers will be determined. The 

 comparison of pest pressure in IPM and non-IPM plots will allow us to evaluate 

 which practices are the most effective with the least pesticide impact. This 

 information will define directions for pest management practices which will be 

 refined in the following seasons. 



We are at the beginning of the program. At this stage, we welcome the 

 comments and advice of any interested people.
