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...
متن کاملInvestigations 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...
متن کاملInteraction of methyl bromide with soil.
Because methyl bromide (CH3Br) is a widely used agricultural fumigant for soil disinfection, it is important to know the chemical behavior and fate of CH3Br as a result of its use for soil treatment. A solid-state 13C NMR study of 13CH3Br-treated soil and soil-component samples shows that methylation of soil organic matter may be the major pathway for degradation of CH3Br in soils. Adsorption o...
متن کاملReactive films for mitigating methyl bromide emissions from fumigated soil.
Emissions of methyl bromide (MeBr) from agricultural fumigation can lead to depletion of the stratospheric ozone layer, and so its use is being phased out. However, as MeBr is still widely used under Critical Use Exemptions, strategies are still required to control such emissions. In this work, novel reactive films (RFs) were designed and their efficacy in limiting loss of MeBr from soil was te...
متن کاملActual hazard of methyl bromide fumigation in soil disinfection.
Methyl bromide, a highly toxic and ready penetrating fumigant, is widely used against rodents, insects, mites, and a range of pathogenic organisms in soil, compost, and timber. To disinfect soil in greenhouses, methyl bromide is brought under pressure from outside by a vaporiser and blown on to ground under a polyethylene cover. The gas being three times heavier than air easily penetrates the g...
