Better WOOSTER, Ohio Applying insecticides with modem equip ment and only when and where heeded reduced the amount of chemicals applied to high-value row crops by about 50 percent. T.L. Ladd, Agricultural R Research Service research en :omoiogut, used a sprayer turned in and off automatically by a photoelectric control. The in termittent sprayer was developed and tested by Agricultural Research Service agricultural engineer Donald L. Reichard. It projects an infrared light beam across the plant row as the machine moves across the field Plants interrupting the bght beam automatically trigger the unit and get sprayed. When the light is not interrupted, no spray is applied. Ladd and Reichard have been working with various intermittent sprayers and application systems for several years For the first time they have used the photoelectncally controlled k==lF=dr=sir=lr=it=Jts=m RALPH HALL DISPERSAL Savocool Hills Rd. off Cobb St., Broton, Thompkins County, NY WED.

Ladd checked both spring- and summer-transplanted cabbages for signs of cabbage loopers and imported cabbage worms. When numbers reached a potentially damagmg level, he applied an insecticide treatment. The researchers, including Ohio Agricultural Research and Development Center entomologist Donald E Simonent, are all stationed at the Center, Wooster, Ohio They compared the amount of chemicals used by their system with a weekly insecticide ap plication by a continuous spray system typically used in production of commercial fresh market cabbage “We used less than half as much insecticide on the summer planting with our system as we did with the weekly, continuous spray method," Ladd says “When we used the intermittent sprayer weekly, regardless of the insect Annual Heifer Sale Located on the Robert Mullendore Farm, 10 miles south of Hagerstown, Md. on the Boonsboro-Williamsport Road (Route 68), 3 miles west of Boonsboro, Md. or 2 miles east off Sharpsburg Pike (Route 65) at Lappan Crossroads FRIDAY EVENING, MAY 28 at 7:00 P.M. 300 Head of Livestock 300 Consisting of from 200 to 300 head of Holstein heifers ranging started calves to some good close springing heifers.

Insect infestations in cabbage transplanted in the spring were so small and late that both the con tinuous and the intermittent treatments based on population evaluation used 75 percent less insecticide than the weekly, continuous spray treatment The intermittent treatment, applied weekly, used 21 percent less in secticide than the continuous sprayer “No significant differences existed in the numbers of insects or in the quantity or quality of cab- produced under any of the spray' systems,” he says. “All treated plots of summer cabbage yielded at least 50 percent more less than untreated plots In fact, for the fresh market, nearly all the untreated cabbages were un marketable.” The differences in the amount of insecticide used are largest while plants are small After plants grow to fill in the entire row, the in termittent sprayer applies in secticide most of the time anyway, the same as the continuous sprayer, Ladd adds “It seems to me that photoelectncally-operated in termittent sprayers, used in conjunction with ' ulat: Three spray nozzles like this one are activated when a plant interrupts an infrared light team.
