A32-L«ncastsr Fanning, Saturday, March 18,1989 Pre-planting Herbicides (ContiniMd from Pag* A 1) coverage on the seed. Pre-planting incorporation woks very well for those herbi cides which are actually degraded by the sunlight Also, most those herbicides which are most volatile lose less of their power when used this way prior to planting. There is also less variability in weed control when using pre-plant incorporated herbicides. Efficien cy should be between 80-90 percent. There is a big advantage when pre-planting herbicides are used to control large seed weeds because the herbicide can be incorporated 2-3 inches deep where the weeds actually germinate. This is super ior to the surface application which depends on the rain to carry and the rain won’t carry* to the level of germination. Using pre-plant hrebicides, although it does postpone plant ing, forces the farmer to get his weed control work done first. That’s a big plus. Trying to con trol weeds when the farmer can see them is sometimes too late and not cost effective. Pre-emergence herbicides are far superior to other programs for use. Because there is no diluting as in post emergence to protect the crop, pre-emergence allows a higher concentration of chemical application. One big “must” with pre emergence is th euse of markers on the sprayer to mark the field. How many farmers arc able to spread or spray without markers and not come up with some skipped strips. New Products To Look For Some new materials are coming up for use with com. According to Yocum Accent® should be realty by next spring. Agronomists were hoping for die EPA to see an emergency situation and make it available in 1989 because it is far superior to enything in controlling shattercane. Tough® is a post emergence herbicide for com which will also be available next year. It is excel lent in test plots controlling 3-4 inch high pigweed and lambsquar ters and on Triazin® resistant weeds. One drawback Yocum noted. Tough 0 stinks. If it works of course, most farmers won’t care, but those fanners near urban areas will need to be concerned because it draws attention to their herbi cide use and application. Also, there is a label change for Prowl® for use with no-till com, but the seed must be I'A ” deep. Harmony® is the new product for use with wheat and barley. It is excellent in controlling wild garlic and chickweed. It must be used with a surfactant or it won’t work. Liquid nitrogen has shown to work best with it It works slowly, Yocum cautioned, but it does work. The plant stops growing when it comes in contact with Harmony®, but the effects do not appear for nearly two weeks. For alfalfa Buctril® is effective in controlling wild radish, but a caution here. If the next three days are to be in the 70 degrees, don't use, it won’t work. For soybeans Pursuit®, a post emergence, is an excellent control for velvet leaf and giant ragweed. Its advantage over Scepter is that it gives the fanner better control over velvet leaf. Assure® and Option® have been shotfn no effectively control the warm sea Do you want to go back to mechanical cultivation? The environmental impact of agri-chemical use is being increas ingly scrutinized. Chemical use replaced the need for mechanical cultivation. However, cultivation can reduce the need or eliminate the need for chemical use. But unfortunately there is much more to the chemical versus mechanical debate. Lynn Hoffman, senior research associate with the Penn State Agronomy Department noted that between the all-mechanical and all-chemicals weed control prog- director of Chester County Soli and Water Conservation presented the USDA’s Bicentennial Farm Award to Robert Kolle. Six families in Chester County were honored for farm ing the same land for2oo years or more. They were: Thomas Martin of West Grove; William Handy of Coatesville; Robert F. Cochran of Cochrenville; Charles McFartan of Downing town; Jane (Kreuger) McElhenny of Honey Brook; and Mar ian Kolia of Pottstown. rams there is a lot of room for opportunity to reduce the environ mental impact and chemical man agement ability of the farmer. There are drawbacks to the mechanical side. It'moves away from minimum tillage systems, destroys beneficial crop residues and anyone who remembers culti vating corn, knows it is a slow, slow process. Hoffman asked in this high gear industry, who has that kind of time? For those who are attracted to this idea there are a variety of cul tivator tools and they are complex machines with many adjustements critical to the success of your crop. To be considered are depth of cultivation around crop, closeness to crop and possibility of plowing Say "WO" to new taxes! The Pennsylvania Formers' "NO!" ou? Association says How about Do you want to raise the federal tax bite to provide more monies or hold new spending to the available revenues? The answer is not more taxes. The answer is "CUT SPENDING!" New Federal Income is Estimated To Be More Than $BO Billion This Year ...

(Turn to Pago A 42) Dave Pierce received the Clean Water award pre sented by the Chesapeake Bay Program for hli toil conser vation and nutrient management practices on his 130-acre farm near Lincoln University In Chester County. Pierce was the first Chester County farmer to sign up for the program. He was recently named the regional winner of . the Clean Water award.
