Management of sugarcane whitefly, Aleurolobus barodensis (Mask.) under south Gujarat
Research Type
Departmental Research
Experiment Background
Sugarcane is an important cash crop in agriculture sector of India. Sugarcane is a main source of sugar in the world. About 60 per cent sugar of the world production is obtained only from sugarcane. Production and productivity have been affected by several insect pest and diseases which are major constraints and responsible for low productivity and production of sugarcane in India. These biotic stresses are also reduced the sugar recovery in sugarcane. Sugarcane is known to be attacked by about 228 insects and non-insect pests in India (David and Nandagopal, 1986).
Sucking pest like whitefly are the major constrain in the cane production. There are three species of whiteflies viz., Aleurolobus barodensis Maskell, Neomaskellia bergii Sign and Neomaskellia andropogonis Corbett attacking the sugarcane. Among them, A. barodensis is the important one. The leaves turn yellow and/or pinkish in case of severe infestation. It’s attack in the early stages of crop growth results in a serious setback to the crop and at the later stages causes deterioration in the quality of juice. In addition, sooty mould develops on the honey-dew exuded by this insect, interfere with the photosynthetic activities of the leaves, render the tops of canes unfit as cattle feed (Nikpay and Goebel, 2016). The losses by this pest to the tune of 15-20 per cent in cane yield and 1-2 units in sugar recovery and 41.9 per cent in sucrose content of juice have been reported by Gupta and Nagar, 1951 and (Singh et al., 1956). In the recent past, sugarcane whitefly causes enormous losses to the sugarcane under south Gujarat condition particularly Navsari, Valsad, Surat, Tapi and Bharuch district cane growing areas and the same issue has been raised by all the Sugar factories of the zone and farmers to the University to urgent solution at least ad-hoc recommendation.
Therefore, it is felt necessary to give the urgent remedy to the farmers against sugarcane whitefly. Hence, an experiment on management of sugarcane whitefly,
A. barodensis through insecticides in combination with cultural methods against under South Gujarat conditions is proposed with following objectives.
