The Studied data of Chilli fruit borer revealed that the Insecticides and neem based insecticide shows, after spraying various treatments in each plot the observation recorded against each replication on weight of healthy fruit and weight of damage fruit data reported in maximum weight of damage fruit were observed in Untreated plot T4, i.e. (1.450 kg) and also the minimum weight of damage fruit were observed in T1 Malathion (0.04%) i.e. (0.300 gm) respectively were observed in plot. We also compare T2 (Methyl Dematon 0.02%) and T3 (Neem Oil 0.03%) then observation are come out. The maximum weight of damage fruit in T3 (Neem oil 0.03%) is (0.480) and minimum weight of damage fruit in T2 is (0.480). It is clear that from table that among all treatment T1 Malathion (0.04%) is the best treatment as same T1>T2>T3>T4 in fig. no. 02 then weight of healthy fruit per plot against each treatments showed that T1 (Malathion 0.04%) is significantly superior over control plot and having maximum weight of healthy fruit is (4.250) in Kilograms and T4 (Untreated water spray) is found minimum is 1.950 in kilograms, hence T1<T2<T3<T4 as mentioned in Fig. No.03. On the basis of fruit weight (Kgs.) per cent losses data showed that maximum per cent of fruit loss in T4 (Untreated water spray) i.e. 47.35% followed by T3 (Neem oil 0.03%) shows less per cent loss of fruit is 14.32% followed by T2 (Methyl dematon 0.02%) is 11.14% and T1 (Malathion 0.04%) is 7.05% means the T1 is found superior, i.e. T1<T2<T3<T4 as mentioned in Fig. no. 04, according to number of fruit damage in each replication against each treatments shows the T1 (Malathion 0.04%) found superior over T4 (Untreated water spray), T1 (Malathion 0.04%) is 218 and T4 (Untreated) is 470 number of fruit were damaged then in comparison of T2 (Methyl dematon 0.02%) & T3 (Neem oil 0.03%) observed that T2<T3 and T3 is 260 followed to T2 is 244 number of fruit damaged, hence T1<T2<T3<T4 (as showed in fig. No. 05) and total number of healthy fruits were observed in treatment in each replication is T1 (Malathion 0.04%) followed by T2<T3 and <T4 respectively, i.e. 2,435 & 2,320 and 1,290 so T1<T2<T3<T4 (is found &mentioned in Fig. No. 06), then on the basis of number of fruit damaged in per cent were revealed that the T1 (Malathion 0.04%) is 8.25% is found most superior than T2 (Methyl dematon 0.02%) is 10.02% < T3 (Neem oil 0.03%) is 11.20% followed by T4 (untreated water spray) is 37.90% respectively and T1<T2<T3<T4 is found after study, (Showed in Fig. No. 07).
