MetadataShow full item record
AbstractDICA (3, 4-dichloro-5-isothiazole carboxylic acid) is being used as a chemical hybridizing agent in the cotton breeding program of Chembred Seed Company. This compound produces male sterile flowers. Registration of this compound by EPA requires that a plant residue study be conducted to provide data on the quantitative amounts of residues in F₁ plants and seeds, F₂ seeds and in the soil. This study was carried out in Arizona because the hybrid F₂ cotton seeds will be grown in Arizona.
