Selective Chemical Control of Cocklebur in Cottonseed

Weed Science, 1971
Several chemicals were evaluated for their potential use in selectively killing cocklebur (Xanthium pensylvanicum Wallr.) seed in cocklebur-cottonseed (Gossypium hirsutum L.) mixtures. Reduction in cocklebur embryo viability from 64 to 100%, without injury to cottonseed, resulted from soaking seed in: (a) 20% ethyl or methyl acetate and 80% water for 3

Peanut Genotype Response to Interference from Common Cocklebur

Crop Science, 1991
Weeds can cause serious yield reductions in peanut (Arachis hypogaea L.). Genetic differences have been found in several crop species for tolerance to weed competition, but no such findings have been reported for peanut. Field experiments were conducted in 1987 and 1989 near Gainesville, FL, to determine the effects of interference by common cocklebur (

The Cotyledon in Relation to Photoperiodism in Cocklebur

Botanical Gazette, 1954
1. Cotyledons of cocklebur were exposed to 8-hour photoperiods either by covering the cotyledons with black cloth sleeves or by placing in a dark room plants with epicotyl removed or undeveloped. No plants so treated bloomed. 2. Plants with cotyledons exposed to 8-hour photoperiods were grafted to plants on 17-hour photoperiods; no floral initiation ...

Translocation of Bentazon in Soybeans and Common Cocklebur

Weed Science, 1976
Translocation of14C-labeled and toxicity of nonradiolabeled bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2,2-dioxide] was determined for common cocklebur (Xanthium pensylvanicumWallr.) and soybeans [Glycine max(L.) Merr.]. Significantly greater14C-movement and herbicide toxicity occurred in common cocklebur growing in wet soil at field ...
