Combating crabgrass used to be a time-consuming and hopeless task, but you can eas ily prevent it from dominating your lawn by applying one ap plication of a pre-emergent herbicide before the seedlings develop. The key is to do so be fore three consecutive warm nights (with temperatures above 50 degrees) combine with moist earth to break dor mancy in crabgrass seed. The little seedlings emerge as light yellow-green leaves, rather wide, and up to one-half inch long. You can stop crabgrass be fore the lilacs bloom this spring by applying any one of five major chemicals (Balan, Dacthal, Betasan, Bandane and Siduron) to your lawn after mowing it twice. Apply chemi cals uniformly by spreading one-half of the suggested quantity in one direction, and the other half by moving at right angles or crosswise. That gives your lawn double coverage. Crabgrass control is easy to jverlook in spring because the weed is an annual and its ini tial growth is slow. But by early July, when hot weather sets in and favors rapid growth, crabgrass can dom inate your lawn until the first frost. Unless you stop crabgrass before it starts, it could be dif ficult to control because it pro duces thousands of seeds and must be sprayed frequently for full control. Since crabgrass flourishes in sunlight, one de terrent is to let your grass grow higher and denser than the weed. If a crabgrass problem per sists annually in your lawn, perhaps your management techniques need improving. When adequate lime and fer tilizer are used, with high mowing (ranging from IV2 to 2Vz inches), crabgrass seldom threatens a lawn □ Handles all sizes and types of twines without knotter adjustment 400 AU-TWINE BALERS Forget about costly down time and missed bales with the International® All-Twine Balers . . . with the knotter that ties a unique bow-type, double diameter knot that test up to 17 percent stronger than ordinary single di ameter knots .. and does it with all types and diameters of baler twine, with out adjustment. • Heavy-duty power train with extra large main drive clutch and precision spiral bevel and pinion gears. • Optional deluxe pickup with up to 126 rubber mounted teeth picks up short hay and hard to feed crops • Economy-priced 420 bales up to 15 tons an hour, 430 up to 17 P tons, 440 up to 19 tons mCome in today and compare features.
