Massachusetts Integrated Pest Management Guidelines for Apple 



To be recognized as an IPM grower, orchardists should accumulate 298 (70%) 

 IPM Practice Points of a possible 425. Points should be earned in each category. 

 Partial credit can be earned for a practice carried out on part of a farm, or partially 

 completed. Practices need to be documented by written records (e.g., scouting 

 records, dates and rates of applications of fertilizer, and dates of sprayer calibra- 

 tions). Practices marked in bold type are considered basic IPM practices. 



Practices marked with an asterisk (*) are advanced IPM (second level) or 

 experimental practices. These practices are presently under evaluation, but appear 

 to be capable of reducing pesticide use significantly beyond that of basic (first level) 

 IPM practices. Bonus points are awarded for completion of these practices. 



NUTRIENT MANAGEMENT AND CULTURAL PRACTICES 



1. Trees are pruned so that spray penetration and air 



circulation are adequate. 5 pts 



2. Primings are removed or destroyed such that no residue is 



present after one year. 5 pts 



3. Summer pruning is done on densely foliated, vigorous trees. 10 pts 



4. A complete leaf tissue analysis is performed in the current year. 10 pts 



5. Fertilizer amendments are applied according to previous year's 



leaf tissue analysis. 10 pts 



6. Orchard renovation (4% of the orchard or greater) includes dwarfing 

 rootstocks (M.26 or smaller) in at least 50% of the new plantings. 10 pts 



PESTICIDE APPLICATION AND RECORDS 



Only pesticides approved and registered in the state will be used. Records of pesticide 

 applications (including date, block identification, targeted pest, pesticide name and EPA 

 number, rate, and number of acres treated) are maintained. Pesticide drift is minimized. 



1. Orchard sprayer is calibrated accurately at the start of the 



season. 10 pts 



2. Herbicide sprayer is calibrated accurately at the start of the 



season. 10 pts 



3. Orchard sprayer is recalibrated at mid-season. 10 pts 



4. The grower has calculated tree-row volume for each block and 



applications conform to tree-row volume calculations. 10 pts 



INSECT MANAGEMENT 



Monitoring 



Insect monitoring must be carried out in a scientifically valid manner. Records should be 

 kept of all monitoring information collected.
