To obtain a more even application rate when using a visual monitor, first increase your sprayer controller speed slightly rather than deciding to replace the nozzles, suggests Doug Summer.

Unlike many pieces of farm equipment, a sprayer is not something that Dad or Granddad absolutely had to buy. When spraying became common to cropping operations, there was an opportunity to outsource it to a custom applicator and avoid tying up the capital and adding to the responsibilities of the already over-worked farmer.

Given the high cost of applying pesticides in your fields today, replacement of worn nozzles is the best insurance against waste. The investment in a set of new spray nozzles is dwarfed by the cost of the chemicals being applied. But when should nozzles be replaced?

For more timely no-tilling, John Deere in late August introduced the 1990 CCS no-till air drill as a replacement for the 1890 model. For big-acreage growers, these new no-till drills offer many options for designing a high-capacity seeding rig to fit your operation.
