I■ i ' Lancaster Farming, Saturday, December 19,1981—D17 Norway spruce and Douglas fir with a combination of several herbicides, including Princep, a product not presently labeled for use on ornamentals at planting. Princep was applied im mediately after planting in combination with either Goal or Deverinal. Spray- formulations included either 1 pint of Goal or 2 pounds Deverinal (a-ctive ingredients) with several different rates of Princep. At the 1 pound rate, Princep, in combination with these materials caused no plant injury to or namentals growing on either sandy soil at the university’s Georgetown Substation, or the heavier soils of the experimental farm in Newark. Materials were applied over'the top immediately after planting on weed-free ground. Though results were promising, Dunham thinks it is very im portant that the soil be well firmed around plants if they are to resist herbicide injury. This is easier to do if you’re planting by hand, rather than by machine. In a related demonstration, Dunham has been evaluating the effectiveness of the Herbi sprayer as a low-cost, low-labor means of applying herbicides on nursery stock, including Christmas trees. Advantages of the sprayer are that it applies very low volumes of material per acre. This means that with one filling, you can cover a large number of trees. The equipment is light and easy to handle. “I think the Herbi has a place in ornamental production,” he says. “The main disadvantage we en countered was that the volume put out is so low that it’s hard to realize you’re putting any material on.” This poses a psychological problem for the person doing the spraying in the sense that it may seem that the job isn’t getting done. You have to be careful not to overtreat. Tests showed that the sprayer is effective in applying flowable pre emergence herbicides such as Princep, Deverinal, Goal and Lasso. It is also very effective in applying post-emergence materials such as Roundup. Roundup cannot be used where foliar contact is a potential cause of injury. All indications are that despite the low volume of water applied per acre, the effectiveness of the materials is much the same as when comparable rates of her bicides are applied by other methods, says Dunham. He feels the Herbi offers a very efficient low-cost method of applying weed control chemicals. Being hand held, it can be used in areas dif ficult to reach with mechanical equipment. During the past two years, Dunham has worked on weed control problems encountered the previous year. Using spring planted Norway spruce, Douglas fir, white pine and Colorado spruce, he has been able to find the most effective control and rates of herbicide application on young trees of these species.
