Description

Inter-row weeding is indispensable for organic farming; however, it is not widely used in Québec for narrow-row crops. With the development of a narrow-row crop weed control strategy, along with early passes of the rotary hoe and tined weeder, farmers would be able to intervene later in the crop cycle and achieve greater control of larger weeds.

The use of a guidance system (e.g., camera or GPS) for very narrow rows could yield greater accuracy at higher speeds. Narrow-row crop weeding will be studied in four experiments conducted on three crops, i.e., green beans, peas, and soybeans. The experiments will take place over three years at the Saint-Bruno-de-Montarville Organic Agriculture Innovation Platform.

Objective(s)

  • Establish a weed control strategy for narrow-row crops using late weeding—along with early passes of the rotary hoe and/or tined weeder—under optimal conditions.
  • Determine
    • the appropriate tools and speed for weeding narrow-row crops;
    • the optimal time to weed;
    • the effect of row spacing and the use of access roads, and
    • the impact on speed and accuracy of adding a camera-guided system to the weeder.
