Is paraquat used on potatoes?
Studies using Paraquat herbicide for early post-emergence control of broadleaved and grass weeds in Katahdin and Russet Burbank potatoes were conducted in Maine during four growing seasons. Paraquat can be used effectively for weed control in Katahdin up to one week after ground crack without crop damage.
Why do farmers kill potatoes?
Tuber maturation can be artificially induced by killing the potato vines prior to harvest. This will benefit tuber ap- pearance, limit tuber size, and improve tuber release from the vine, facilitating harvest operation. Another benefit of vine killing is the avoidance of disease and improved storage.
How many times do farmers spray potatoes?
Start spraying main crop potatoes once the foliage is 10-15 cm tall. Continue spraying at 7 day intervals up to the time of burning off. Burn off two to three weeks before harvest to prevent tuber infestation. The chemicals used to control blight fall into four main groups.

How are potato plants used for weed control?
Cultivation can also greatly reduce weed populations if already emerged. Herbicides are a principal component in most potato weed control programs. Herbicide choice depends not only on present weed species, but on soil type, cultural practices, potato cultivar herbicide tolerance, and herbicide availability.
When to apply pre emergent herbicide to potatoes?
Outlook herbicide provides potato growers with powerful, consistent control of grasses and small-seeded broadleaf weeds that can impact their crop. The pre-emergent herbicide should be applied between planting and crop emergence to reduce early-season competition and ensure the potato crop gets off to a strong start.
How did the herbicide Dow affect the potato industry?
Problems with the herbicide emerged late last year, when some commercial potato growers reported damaged crops. In response, Dow launched a campaign within the agriculture industry to ensure that farmers were aware of how the products should be used. Nevertheless, the herbicide has now entered the food chain.
