Weed Control in Strawberry Runner Plant Nurseries with Methyl Bromide Alternative Fumigants

Drip Application of Alternative Fumigants to Methyl Bromide for Strawberry Production

Strawberry (Fragaria ×ananassa Duchesne) is a high-value cash crop that benefi ts from preplant soil fumigation with methyl bromide (MB) and chloropicrin (CP). Methyl bromide will be banned in the U.S. and other developed countries by 2005 for most uses. Potential alternative chemicals to replace methyl bromide for soil fumigation include CP, 1,3-dichloropropene (1,3-D), and methyl isothiocyana...

Weed Control in Southern Hardwood Nurseries

In the South, most nursery managers have relied on methyl bromide for weed control in hardwood seedbeds. When methyl bromide is no longer available, handweeding times will likely increase unless management regimes adapt to the change. Some nursery managers will increase use of both sanitation practices and herbicides. Although several herbicides are registered for use on hardwoods, some can inj...

Winter Strawberry Production in Greenhouses Using Soilless Substrates: an Alternative to Methyl Bromide Soil Fumigation

In an effort to develop an alternative to methyl bromide-dependant strawberry (Fragaria x ananassa Duch.) field production in north-central Florida, we evaluated various soilless substrates, growing containers, plug transplants, plant densities, cultivars, and biological control strategies in a passively ventilated high-roof greenhouse near Gainesville, Florida. The type of soilless media used ...

Investigations on Adverse Properties of the Fumigants Methyl Bromide and Phosphine. 1. Residues of Methyl Bromide in Fumigated Commodities

1. The mode of action of phosphine and development of insect resistance. 2. The corrosion of copper by phosphine. 3. The mode of action of methyl bromide and its relationship to insect resistance. 4. Residues of methyl bromide and the reaction products formed in treated foods. In this conununication are given some results from one of these studies, i.e. residues of methyl bromide occurring in f...
