​Defoliants Harvest-aid Chemicals: Cost Effective Technology to Facilitate Synchronized Maturity for Mechanical Harvesting in Cotton: A Review

In the recent years, increasing labour cost and shortage of being major constraints to follow manual harvesting in cotton staggered manner. Further, it is very expensive farmers would like increasingly opt for mechanical harvesting. this context, suggested that research should focus reduce cultivation substantially by promoting use synchronized maturity defoliants encourage agriculture, are used eliminate leaves a crop plant so they do not interfere with machinery. Early good boll opening can also be achieved defoliants. The reduces trash content picked which will help improving quality cotton. There need identify suitable defoliant dose time application as facilitate rainfed Some successful uniform bursting higher yield such rthrel, rthepon, mepiquat chloride (MC), sodium salt DU (Dropp Ultra) hormonal TDZ thidiazuron butifos, merphos, tribufos tribufate herbicidal best combination + diuron (DCMU), pyraflufen ethyl, diuroncellular isozyme, Ethephon AMADS, ethephon cyclanilide Mepiquat (MC) may recommended
