What is the spacing between chisels on a tool bar when using chisel applicators?

  1. 5-7 inches

  2. 8-10 inches

  3. 10-12 inches

  4. 12-14 inches

The correct answer is: 10-12 inches

The correct spacing between chisels on a tool bar when using chisel applicators is 10-12 inches. This distance is designed to ensure effective and uniform application of the fumigant. Spacing that is too close can result in overlapping applications, which can lead to excessive residue and potential crop damage, while spacing that is too far apart can result in inadequate coverage and reduce the effectiveness of the treatment. The specified range of 10-12 inches strikes a balance that helps achieve optimal distribution of the fumigant within the targeted area. This spacing is particularly critical for achieving consistent results, especially in agricultural settings where precise application is necessary for both efficacy and safety.
