A field experiment was conducted for management of shoot fly, Atherigona aproximata, Malloch and stem borer, Chilo partellus Swinhoe in pearl millet crop between 2006-07 to 2010-11 at Millet Research Station, Junagadh Agricultural University, Jamnagar. The results indicated that farmers of North Saurashtra Agro-climatic zone growing bajra crop are advised to apply two sprays of profenophos 0.05 per cent or fenobucarb 0.1 per cent at 20 and 40 days after germination for the control of shoot fly and stem borer infesting bajra crop.Keywords

Monitoring of adults of ear head worm Helicoverpa armigera (Hubner) through male sex pheromones was studied during Kharif 2002 to 2011 in pearl millet crop at Jamnagar, Junagadh Agriculture University, Junagadh. Highest number of moth catches was recorded during 35th MSW i.e. 27th August to 2nd September. Adult moth catches were found negatively correlated with maximum temperature (r = -0.1698). Farmers are advised to install sex pheromone trap for monitoring and mass collection of adult male moth of H. armigera @ 5 traps/ha at a height of 2.0 m from 1st week of August to 2nd week of September.Keywords

Seasonal incidence of groundnut jassid, Empoasca kerri was studied during summer 2014-15, at College of Agriculture, Junagadh Agricultural University, Junagadh. Groundnut crop was infested by jassid, Empoasca kerri. The study revealed that the incidence of jassid started in 2nd week of March which gradually increased and touched its peak during 3rd week of April and then decreased in 4th week of May. Relative humidity showed significant negative correlation with jassid population. Minimum temperature, mean temperature, evaporation and bright sunshine hours showed positive correlation with jassid population whereas, maximum temperature, morning relative humidity, mean relative humidity and wind speed showed negative correlation with jassid population.Keywords

Investigations on evaluation of different bio pesticides against pearl millet ear head worm, Helicoverpa armigera in pearl millet crop were made at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif 2015. Insecticides used in experiment were spinosad @ 0.014 per cent, indoxacarb @ 0.0079 per cent, Beauveria bassiana @2.5 kg/ha, Lecanicillium lecanii@ 2.0 kg/ha, HaNPV @ 500 LE/ha, azadirechtin @ 0.000375 per cent and Bacillus thuringiensis @1.5 kg/ha. Among the eight treatments, spinosad @ 0.014 per cent and indoxacarb @ 0.0079 per cent was found to be most effective in reducing the larval population of H. armigera. The treatments HaNPV @ 500 LE/ha, B. thuringiensis @1.5 kg/ha and azadirechtin @ 0.000375 per cent found moderately effective for the control of this pest. L. lecanii @ 2.0 kg/ha and B. bassiana @2.5 kg/ha proved to be least effective against pearl millet earhead worm. Spinosad @ 0.014 per cent recorded the highest grain yield of pearl millet (2685 kg/ha) and it was at par with indoxacarb @ 0.0079 per cent (2477 kg/ha). As far as economics of various insecticides are concerned, the treatments of HaNPV @ 500 LE/ha or spinosad @ 0.014 per cent or azadirechtin @ 0.000375 per cent were found as effective and economical as recommended synthetic insecticides and are recommended for eco-friendly management of H. armigera in pearl millet ecosystem.Keywords

An experiment was conducted to evaluate the bio-efficacy of bio-pesticides against jassid, Empoasca kerri Pruthi infesting groundnut at Instructional Farm, College of Agriculture, Junagadh during Summer season of 2014-15. The results revealed that thiamethoxam 0.01 per cent and acetamiprid 0.004 per cent were found most effective treatments against the pest. Among the bio-pesticides, combination of B.bassiana @ 1.25 kg/ha + thiamethoxam 0.005 per cent was found most effective against jassid. While the combinations of V. lecanii @ 1.0 kg/ha + thiamethoxam 0.005 per cent was found moderately effective against jassid. Thiamethoxam 0.01 per cent recorded the highest pod yield of groundnut (1344 kg/ha) followed by acetamiprid 0.004 per cent (1275 kg/ha). As far as economics of various insecticides are concerned, thiamethoxam 0.01 per cent gave the highest cost benefit ratio (1:17.82) followed by B. bassiana @ 1.25 kg/ha + thiamethoxam 0.005 per cent (1:13.96).Keywords

Investigations was conducted to evaluate bio-efficacy of some new molecules of insecticides against major sucking pests of summer cowpea at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during summer 2016 with ten treatments and three replications. Among the tested insecticides, dinotefuran 0.006 per cent, acetamiprid 0.004 per cent and dimethoate 0.03 per cent were found most effective against jassids. The treatments of acetamiprid 0.004 per cent, dimethoate 0.03 per cent and spiromesifen 0.08 per cent were found most effective in reducing the whitefly population. The application of dinotefuran 0.006 per cent acetamiprid 0.004 per cent and dimethoate 0.03 per cent proved effective in recording minimum aphid population. The highest grain yield of cowpea 853 kg/ ha was recorded from the treatment of dinetofuran 0.006 per cent which was statistically at par with acetamiprid 0.004 per cent (816 kg/ha), spiromesifen 0.08 per cent (795 kg/ha), dimethoate 0.03 per cent (790 kg/ha) and flonicamid 0.02 per cent (752 kg/ha). On the basis of economics, acetamiprid 0.004 per cent (1: 21.8) proved to be most economically viable treatment followed by dimethoate 0.03 per cent (1:21.2), spiromesifen 0.08 per cent (1:9.8), dinetofuran 0.006 per cent (1:9.4), chlorfenapyr 0.0075 per cent (1:5.8), clothianidin 0.003 per cent (1:5.5) and flonicamid 0.02 per cent (1:4.8).Keywords

Population dynamics of Helicoverpa armigera in pearl millet was studied during Kharif 2015 at Instructional Farm, Junagadh Agricultural University, Junagadh. The study revealed that the pest incidence commenced from seventh week after sowing in variety GHB-558 and was found active from August to September in the crop. The pest population increased in the last week of August and reaching to a peak level of 1.56 larvae per ear head. Then it was decreased (0.82 larvae/ear head) during the first week of September and remained active steady upto second week of September. Among the different parameters, maximum temperature and mean bright sunshine hours showed positive correlation whereas minimum temperature, morning relative humidity showed negative correlation with population of this pest but did not reached at significant level. However, the correlation between the pest population and evening relative humidity was significant and negative. Rainfall exhibited a non-significant and negative correlation with the pest population.Keywords

Investigations were carried out on seasonal incidence of major sucking pests that attack the cowpea at College Farm, Junagadh Agricultural University, Junagadh during summer 2016. The result revealed that jassid population initiated from the second week of March with 0.48 nymph/3 leaves/plant and reached a peak (4.91 nymphs/3 leaves/plant) in first week of May. The population of whitefly and aphid also appeared from the second week of March and reached to a peak of 4.99 whiteflies/3 leaves/plant and 3.82 aphid index/plant during the fifth week of April, respectively. Among the various weather parameters, maximum temperature showed a significant positive correlation with jassid, whitefly and aphid population in summer cowpea. Whereas, wind speed showed negative influence and bright sunshine hours exhibited positive influence on population of all sucking pests in cowpea crop.Keywords

A field experiment was conducted at Pearl millet Research Station, Junagadh Agricultural University, Jamnagar during Kharif 2016 to 2018 to find out the effective and economical control measures against the major insect pests in pearl millet for organic cultivation. The bio-efficacy of different bio-pesticides viz., HaNPV (6×109POB/ml) @ 250 LE/ha, Bacillus thuringinensis var kurstaki @ 5% WP @ 0.01 %, Beauveria bassiana 1.15 WP (2×106 cfu/g) @ 5g/lit, Lecanicillium lecanii 1.15 WP (2×106cfu/g) 5g/lit and NSKE 5 per cent were evaluated agaisnt the major insect pests in pearl millet crop. The treatment of B. bassiana 1.15 WP (2×106 cfu/g) @ 5g/l recorded the least incidence of shoot fly (7.2%) and stem borer (5.36%) at earhead stage of the crop. Whereas, in case of ear head worm Helicoverpa armigera, treatment of HaNPV (6×109POB/ml) @ 250 LE/ha recorded the lowest larval population (5.78 larvae /20 ear heads) and it was at par with B. thuringiensis @ 1.0 kg/ha (8.36 larvae /20 ear heads) and B. bassiana @ 5g/l (9.87 larvae /20 ear heads). The treatment of B. bassiana @ 5g/l also recorded the highest grain yield (1727 kg/ha) followed by HaNPV @ 250 LE/ha (1490 kg/ha).Keywords
