Farm records were used to study the temporal and spatial distribution of bollworm, Helicoverpa zea (Boddie), tobacco budworm, Heliothis virescens (F.), (collectively heliothines) and tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), on cotton, Gossypium hirsutum L., across a 4000 ha farm in southeastern Arkansas. The influence of the percentage of corn, Z. mays L., cotton, rice, Oryz...

This paper describes the strategic use of information technology by the Plains Cotton Cooperative Association (PCCA). TELCOT, ’ computer-based system developed by PCCA, provides cotton traders with functions much like those available to NYSE or AMEX traders. TELCOT is a registered trademark of Plains Cotton Cooperative Association, Inc., Lubbock, Texas TELCOT transformed PCCA from a small cotto...

Cotton is traditionally the most important natural fibre in the apparel industry because of the comfortable wearing comfort and durability of cotton textiles. The chemical finishing of cotton aims to further improve the quality of the cotton fibre, either to overcome some disadvantages of the apparel or to establish additional desirable properties. This paper highlights some current trends in c...

From 2004 through 2005, plots of experimental transgenic cotton lines containing the vegetative insecticidal protein, Vip3A; δ endotoxin, Cry1Ab; and both Vip3A and Cry1Ab were evaluated for efficacy against certain lepidopteran pests. Results showed that the cotton line containing Vip3A was more efficacious against the beet Spodoptera exigua (Hübner) and fall armyworm Spodoptera frugiperda (J....

The polyphagous mirid bug Apolygus lucorum (Heteroptera: Miridae) has more than 200 species of host plants and is an insect pest of important agricultural crops, including cotton (Gossypium hirsutum) and mungbean (Vigna radiata). Previous field trials have shown that A. lucorum adults prefer mungbean to cotton plants, indicating the considerable potential of mungbean as a trap crop in cotton fi...

• Cotton cellulose was modified via in situ phosphine oxide macromolecules. Phosphorus monomer crosslinked with amine Michael addition reaction. Excellent flame retardancy and durability to 50 laundry cycles achieved. Hydrophilicity comfort properties of the treated fabrics were enhanced. Antimicrobial property achieved silver nano particle treatment. A facile methodology durably modify fibers ...

A new cotton recognition method is proposed in this paper. It provides parameters for motion of the manipulator so that it can acquire precise location information of cotton, identify cotton from surroundings correctly, and accordingly pick up them automatically. This method is based on color subtraction information of different parts of cotton. Furthermore, in order to increase accuracy rate o...

Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...
