Philip jjarucci, extension specialist in cranberry ind blueberry culture and research pro- essor of entomology, explained that it is .common fallacy that daytime sprinkler ^e causes scalding since water evapora- ion cools the surrounding surface when prinklers are turned off. â Williams Haines Jr. corroborated ilarucci's observation, noting that the pmperature rose very slowly on his bogs lichen the water was turned off and no Icald effects occurred. Although 100 percentof survey respond- ints irrigate when the temperature jaches 95 degrees F in the shade (or lelter), this practice reflects comprom- rather than a scientifically estab- shed procedure, according to speakers, ince many summer days reach 90 degrees , water usage at this temperature would i excessive, while damage might occur growers were to withhold irrigation for ily the occasional 100 degrees F day. SIXTY THREE percent of grower irvey responses indicate that rot is con- dered to be most prevalent in bogs here vine coverage is thin, while 37 ircent thought rot is more often found in well estabhshed, thickly vined bogs. Annually, rot causes approximately a 3 percent crop loss in New Jersey. Although an aggressive, early fungi- cide application program appears to con- trol rot, Lee suggested the need for further study. Joint research efforts of a plant physiologist teamed with Stretch, Lee said, could identify causes of rot, as well as productive, rot-resistant cran- berry varieties. Meanwhile, fungicide application techniques vary, with a.
