Insecticide use is an important and integral component of crop production system. Insecticide use increased substantially over the years. Insecticide consumption increased by 2158.6 per cent in 2004 over 1982, but now there is declining trend in their use. Indiscriminate use of insecticides also lead to several diseases in human health. Concentration of insecticide in surface and ground water is also a major factor for environmental pollution. Insecticide like Diazinon shows the maximum concentration in surface and ground water. Therefore, the concentration of Diazinon should not be more than the recommended limits i.e. 0.003 μg/l to protect the fresh water aquatic life and also eliminate the lethal effects of insecticide residues in ground water. The status of the insecticide residue in lake water i.e. the areas that were not involved in vegetable or horticultural farming is highest in chlorpyriphos ethyl (which was above WHO limit) while the residual levels of endosulfan sulphate and endosulfan ether found in agricultural soil were higher than those of alpha and beta endosulfan, which indicates that degradation reactions take place mainly in agricultural soil.Keywords

Banana (Musa sapientum) is an important tropical fruit crop in India. External appearance of is important factor which decides the market value of the product. Many banana growers suffer huge monetary loss due to pre harvest eating of insects especially scaring beetle, mechanical injury, damage of foxes etc. In Khowai district of Tripura, the infestation of insect was found to be very high. To address the problem an experiment was conducted in the instructional farm of KVK, Khowai, Tripura, India during the year 2016-17 and 2017-18. Ten numbers of bunches were random selected from an already existing banana cv. SABRI orchard. The experiment was comprises of two treatment- T1 : bunches are covering with 6 per cent ventilated Polythene covers / sleeves of size 200 cm length x 150 cm width x 175 gauge thickness and T2 : not covered or control. It was observed that the banana fruits matured under covered condition were more visually appealing as they were clean and had minimal bruises, especially more large-grade fruit with uniform fullness of fruit within the bunch compared to those grown uncovered. 11.45 per cent more finger length and 7.35 per cent more individual fruit weight was noticed in cover bunches compared to that uncovered. Bunch covering also had a positive on the TSS content of the fruit. Further, bagging helps in shorten the time from flowering to physiological maturity by 10. Thus bunch covering can be recommended for commercial banana orchards in Tripura to produce high quality fruits.Keywords
