Herbicide Recommendations for Pepper Production
By Nathan Boyd Weed management can be a significant issue for many farms that grow peppers using a plasticulture production system. Nutsedge species can penetrate plastic mulches, and broadleaf weeds and grasses can emerge in the planting holes or in the rows between the raised, mulch-covered beds. Fumigants are an important component of weed management. However, except for metam products, …
Herbicide Update for Growers

Hydrogels as Herbicide Carriers in Vegetable Plasticulture
By Ramdas Kanissery and Camille McAvoy Weed management is a fundamental step in the successful production of vegetable crops in Florida under commercial plasticulture production systems. Soil fumigation was one of the most successful means of reducing weed populations. None of the alternatives to methyl bromide have a broad spectrum of activity against weeds. This necessitates the need for a …
Selecting Herbicides for Stone Fruit
By Breanna Kendrick With perennial crops such as stone fruits, growers are limited in their weed management options because they can’t choose practices like crop rotation. Therefore, selection of proper herbicides is critical for effective weed control. Peter Dittmar, assistant professor with the Horticultural Sciences Department at the University of Florida Institute of Food and Agricultural Sciences, specializes in weed …
Hole-Punch Technology Dramatically Reduces Herbicide Use
By Nathan S. Boyd and Arnold Schumann The majority of vegetables grown in Florida are grown on raised, fumigated beds covered with plastic mulch. This production technique has been widely adopted because the combination of plastic mulch and drip tape improves water and fertility efficiency. The use of plastic mulches has many additional benefits, including improved crop quality, reduced water …
