The recent trend toward restricting herbicide use has produced interest in alternative and integrated weed control strategies that include cultivation. As a result, newly developed implements are now available to vegetable growers from Northern Equipment Solutions, but the potential uses of these tools for numerous vegetable crops can be confusing. This describes some of these tools and their advantages and disadvantages.
Flex-tine harrows are used broadcast, both over and between the crop rows. They are most efficient when weeds are in the white-thread or cotyledon development stage. In direct-seeded
crops, such as snap beans or sweet corn, flex-tine implements are used pre-emergence. Tines pass above the planted seed. Harrowing can be repeated post-emergence for control of newly
germinated weeds, but only when the crop is wellrooted. Cultivation intensity can be modified to minimize crop damage. Guide wheels and tine intensity regulate harrowing depth.
The Steketee Finger Weeder
The finger weeder is designed specifically for in-row weed control. The tool has pairs
of ground-driven rotating fingers: two pairs in the front push soil and uprooted weeds away from the crop row; while the third pair pushes soil back into the row, covering weeds that were missed by the other fingers. The weeder is most effective when fingers pass very close to the crop row; therefore, precise cultivation and slow driving speeds are important. The finger weeder is most effective on small-acreage, high-value crops.
Steketee Torsion Weeder
The torsion weeder is mounted on an existinginter-row cultivator for improved in-row weed
control. This simple tool has spring-loaded steel rods on each side of the crop row that undercut small weeds. The width of the uncultivated strip is easily adjusted for each crop and development stage.
