n this video, I will explain the best strategy to control white fly in cotton fields. Actually adults and nymphs of whitefly are found in cotton crop and both sucks sap from leaves etc.
White fly adults age is not more than 6 days so nymphs are more dangerous than adult white fly. Whitefly nymphs are attached to bottom sides of leaves and suck sap continuously. They excrete on which fungus attack and we observe sooty mould and sticky oily material in cotton crop plants.
The best insecticide to control whitefly is Pyriproxifen as it kills nymphs. Repeat spray with 6 days interval is must to break down the pressure and generation of white fly. Cotton whitefly (Bemisia tabaci) is the most important sucking insect which flares up under dry conditions. Movento 240 SC (spirotetramate) is considered as an important but very technical insecticide to manage whitefly preferably in cotton crop. In this video, we have explained that for proper results, this insecticide needs two consecutive sprays with an interval of 6 days. Whitefly can only be managed if it is applied twice at the economic threshold level within a period of 50 days after planting or so. When colonies are developed and severe attack of whitefly is faced after 60-90 days of planting, it becomes difficult to manage it with this insecticide.
Malvacy family of plants is more susceptible to insects like Whitefly (Bemisia tabaci), jassid (Amrasca bigutulla bigutulla), thrips (Thrips tabaci)

Leaves of crop plants are a food factory for flowers, fruits etc. They need to clean and lush green to keep the food making process (photosynthesis). Sometimes, blackening on cotton leaves is observed in cotton fields which is misleading to black aphid by cotton growers. Actually it is white fly pest severe attack.
Whitefly is a sucking pest in cotton crop which weakens the plants by sucking sap from leaves and fruiting parts of crop plants and by excreting secretion which is attacked by fungus and ultimately cotton leaves look black and stop the food making process (photosynthesis).
White fly needs to be controlled in these cotton fields where nymph and adults white fly infestation is severe and causing blackening.
Buprofezin and pyriproxifen are effective insecticides against nymphs and flonicamid insecticide is effective against adult white fly. Both can be mixed in a good crop and single can be sprayed in poor crop. Sulphur should be mixed with these insecticides to get rid off blackening fungus.How to control White fly in cotton crop?
In this video, I will shortly explain the controlling method of white fly sucking pest in cotton field.
White fly damages our cotton crop by sucking in two forms;
Adult whitefly: Its age is 7 to 8 days and it sucks sap in small quantity.
Nymphs of whitefly: It's age is 10 to 15 days and they suck saps in large quantity without any break so because of their feeding habit, these are necessary to control before adult white fly.
Moreover, when crop height is 5 to 6 feet then it is very difficult to cover all plant from top to bottom by chemical foliar spray. That s why white flies and nymphs which are found in lower bottom portion of cotton plant continue their feeding and increase their population by making colony. In this scenario, we need some systemic insecticide which moves in whole plant body by xylem and phloem tissues of plants as well. Usually all the insecticides move in xylem tissues.
Movento by Bayer crop sciences is an only systemic insecticide which moves in plants xylem and phloem tissues as well. This is known as two way action of Movento. So white fly present in any part of plant will be killed by its foliar spray. Movento can stop our cotton crop blackening by killing nymphs of white fly.
Movento contains Spirotetramate active ingredient.
Movento is safe in beneficial insects so we can add it in our IPM Techniques program.
Movento dose for cotton crop is 125 ml + 250 ml Bio power.
Use 120 liters of water for it's spray.
Rapeat spray after 7 days for complete control.
Spray should be done before sun rising time or in evening time.
