Herbicidal Control of Weeds in Coffee Seeded in Plastic Bags

Abstract

Results of a screening experiment using three soil fumigants and nine pre-emergence herbicides on coffee seeded in plastic bags indicate that it is possible to seed coffee directly in bags and grow the plants for at least 90 days with excellent growth and satisfactory control of weeds. Fumigation of the soil in the bags with methyl bromide before planting was a highly effective treatment. SMDC was slightly less effective and allyl alcohol gave extremely poor results. Pre-emergence applications of DNBP, and 2-lb. treatments with Diuron, Simazine or Atrazine were reasonably effective. Amizine at 2 lb./acre was highly effective for controlling weeds in plastic bags.
