Effectiveness of integrated management approaches using blue sticky trap, pheromone trap, bio and synthetic insecticides were evaluated against major insects, like flower thrips and pod borers of mungbean at Regional Agricultural Research Station, Rahmatpur, Barishal and Pulses Research Centre, Ishurdi, Pabna, Bangladesh, respectively, during two consecutive years of 2018 and 2019. All of the management packages significantly reduced flower infestation, thrips population and pod borer infestation in mungbean. The highest percentage of reduction of flower infestation, thrips population and pod borer infestation was found in IPM package-3: installing blue sticky trap + two spraying of chlorfenapyr (Intrepid 10 EC) @ 1 ml/l + third spraying with (chlorantraniliprole + thiamethoxam), i.e. Virtako 40 WG) @ 0.15 g/l, followed by IPM package-1, IPM package-2 and recommended practice (spraying imidacloprid, i.e. Imitaf 20 SL @ 0.5 ml/l). The highest yield was also recorded from IPM package-3, which was statistically similar to IPM package-1, followed by IPM package-2 and recommended practice. Although the IPM package-3 provided the highest yield and return, followed by IPM package-1, but recommended practice (farmer’s practice) gave the highest benefit because of higher cost of IPM components brought down the profit margin of IPM packages. The components of IPM package-1, i.e. biopesticides, are ecologically safer than that of IPM package-3 (synthetic chemical insecticides). So, considering environment friendliness, the IPM package-1: installation of blue sticky trap and pheromone trap + two spraying of azadiractin (Biomeem plus 1EC) @ 1 ml/l + third spraying with spinosad (Success 2.5 EC) @ 1.2 ml/l would be the best package for controlling flower thrips and pod borers of mungbean with higher yield in the insects prone areas, without harming the ecosystem.

Efficacy and profitability of different management packages comprising white sticky trap, biopesticide and synthetic insecticides were evaluated against flower thrips and pod borers of mungbean at Pulses Research Center, Ishurdi, Pabna, Bangladesh during two consecutive seasons of kharif-1, 2015 & 2016. All the treatments significantly reduced flower infestation by thrips and pod borer infestation. The highest percentage of flower infestation and thrips population reduction was observed in installing white sticky trap + spraying of chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG) followed by farmers practice, i.e. spraying imidacloprid (Imitaf 20 SL). Again, the highest pod borer infestation reduction was found in installing white sticky trap + spraying azadirachtin (Bio-neem plus 1EC) + spraying with spinosad (Success 2.5 SC) treated plots followed by installing white sticky trap + spraying chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG). The highest grain yield was obtained from installing white sticky trap + spraying chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG), but the highest return came from farmers practice (spraying Imidacloprid). This might be due to the higher cost of Intrepid 10 SC and Proclaim 5 SG reduced the return as well as benefit. Therefore, considering the efficacy and benefit, it is seen that the evaluated IPM package could not be profitable against low level infestation of flower thrips and pod borer infestation. It could be profitable that areas where serious out break of flower thrips and pod borer occurs.Jahangirnagar University J. Biol. Sci. 7(1): 55-64, 2018 (June)

The field experiment was conducted at Pulses Research Centre (PRC), Ishurdi, Pabna and Regional Agricultural Research Station (RARS), Jamalpur during rabi 2012-2013 to find out the effect of seed rate and walkway for green pea production as relay cropping with transplanted Aman rice. The experiment was based on six seed rates @ 50, 60, 70, 80, 90 and 100 kg ha-1 and two walking ways viz. 15 cm wide walkway at 2 m interval over the plot and control with three replications. A local cultivar of pea, named Natore was used in this trial. Results revealed that the treatment with 100 kg seed ha-1 gave the highest pod yield of 5.13 t ha-1 and 4.98 t ha-1 at Jamalpur and Ishurdi locations, respectively which was similar to 80 (S4) and 90 (S5) kg seed ha-1.. Walkway had no significant variation in yield and yield contributing characters but it produced the higher yield over the control. Using walkway, 100 kg seed ha-1 (S6) and 15 cm walkway at 2 m interval over the plot (W1) produced the highest pod yield of 5.14 t ha-1 and 4.95 t ha-1 and fodder yield of 6.70 t ha-1 and 6.13 t ha-1 at Jamalpur and Ishurdi locations, respectively. Maximum gross margin of Tk. 1,06,040 ha-1 and Tk. 1,02,401 ha-1 was contributed by combinations of using 100 kg seed ha-1 and 15 cm walking way but maximum benefit cost ratio (BCR) of 3.40 and 3.43 were obtained from S5×W1 combination at Jamalpur and Ishurdi locations, respectively. It is concluded that pea cultivar can be successfully cultivated for green pod production through the use of 90-100 kg ha-1 seed with walkway of 15 cm wide in the plot after 2 m intervals.

Andropogon gayanus Kunth var. bisquamulatus Hack, is a polymorphic bunch grass, widely distributed throughout most of the tropical and subtropical savannahs of Africa, south of the Sahara in areas with a long dry season. This grass was introduced into the Colombian Llanos from the Shika Agricultural Research Station, northern Nigeria, in 1974. Subsequent to its introduction, a series of agronomic trials were initiated by Centro Internacional de Agricultura Tropical (CIAT) at the Carimagua Research Centre and various national research institutions in Latin America to evaluate the potential of A. gayanus, primarily in the vast Ultisol and Oxisol savannah regions of the continent. As a result of further evaluation at a number of locations, accession A. gayanus var. bisquamulatus CIAT 621 was released in 1980 in Brazil as cv. Flanaltina and in Colombia as cv. Carimagua 1. During 1982–3 Peru, Venezuela and Panama subsequently released the same accession under the cultivar names of San Martin, Sabanero and Veranero, respectively. It is estimated that 168000 ha have been sown with A. gayanus in Brazil since 1982 (J. E. Ferguson, C. Sere and R. de Andrade, personal communication). Smaller areas have been established in other countries.

The experiments were conducted to develop insecticide (Imidachlorpid, Imitaf 20SL at 0.5 ml/l) application schedule for the effective management of thrips and pod borer attacking mungbean during kharif-I season of 2010 and 2011. In both the years, suppression of thrips population and pod borer infestation were higher in double sprayed treatment than single spraying. Single spraying at 35 DAS (100% flowering) and 42 DAS (100% podding stage) suppressed flower infestation by thrips upto 86 and 93%, respectively, during 2010 and 100 & 96%, respectively, during 2011. Double spraying at 42 DAS (100% podding) and 49 DAS (seed developing stage) reduced more pod borer infestation as much as 81-83%. In kharif-I 2010, significantly the highest yield (1798 kg/ha) and MBCR (4.67) were obtained from the plots sprayed twice with Imidachlorpid at 42 DAS (100% podding) and 49 DAS (seed developing stage) but in kharif-I 2011, significantly the highest yield (1457 kg/ha) and MBCR (5.75) were obtained from the plots sprayed twice with Imidachlorpid at 35 DAS (100% flowering) and 42 DAS (100% podding stage). The double spray schedule appeared to be more effective than single spraying against pod borer. But single spray at 42 DAS (100% podding stage) appeared as more effective against flower thrips.

Integrated management of Fusarium wilt of gladiolus was studied at Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during 2011-2013 following RCB design with four replications. Seven treatment such as (1) Corm treated with Bavistin @ 0.1% for 15 minutes, (2) Corm treated with hot water @ 54oc for 5 minutes, (3) Corm treated with hot water @ 52oc for 10 minutes, (4) Poultry refuse @ 5t/ha, (5) Mustard oil cake @ 600 kg/ha, (6) Bio-pesticide @ 64kg/ha, (7) Bavistin @ 0.1% as soil drenching were evaluated in nine different combinations against the Fusarium wilt of gladiolus (Fusarium oxysporum f. sp. gladioli) under naturally infested field condition. Corm treated with Bavistin (0.1%) for 15 minutes + Poultry refuse @ 5t/ha in soil application 25 days before corm sowing + Bavistin @ 0.1% as soil drenching at 45 days after corm sowing gave best integrated management option for reducing Fusarium wilt of gladiolus and thereby resulting maximum germination, spike length, rachis length, florets spike-1, flower sticks, corm and comel yield. Besides, integration of Bavistin (0.1%) as corm treatment for 15 minutes + Mustard oil cake @ 600 kg/ha in soil application 25 days before corm sowing + Bavistin (0.1%) as soil drenching at 45 days after corm sowing was also better option for combating Fusarium wilt of gladiolus. The alternate option was integration of Bavistin (0.1%) as corm treatment for 15 minutes + Bio-pesticide in soil application 7 days before corm sowing + Bavistin (0.1%) as soil drenching at 45 days after corm sowing was effective against the disease incidence as well as better spike length, rachis length, florets spike-1, flower sticks, corm and cormel yield.Bangladesh J.

The experiment was conducted during rabi season 2018-19 and 2019-20 at Regional Agricultural Research Station Jashore to develop a bio-rational based sustainable management approach to control flea beetle of cabbage. The experiment was laid out in a randomized complete block design with three dispersed replications. Cabbage seedlings were transplanted on 10th November 2018 and 11th November 2019, respectively. The experiment was five different treatments with one control treatment viz. T1 = White color sticky trap + Matrin (Biotrine 0.5% @ 1ml/L of water) @ 1ml/L of water, T2 = Spraying of Antario @1.0 ml/L of water, T3 = Alternate spraying of fizimite and Antario @ 1ml/L of water, T4 = Spraying of Bio-clean (D-Lemonine 5% SL) + application of recharge @ 3gm/L of water, T5 = Spraying with Nitro 505EC (Chlorpyriphos + Cypermethrin) @ 2.0 ml/L of water and T6 = Untreated control. The whole plant was thoroughly covered by spray emulsion. The lowest number of flea beetle (14.59 in 2018-19 and 10.33 in 2019-20) was found in the treatment T5 (Spraying with Nitro 505EC (Chlorpyriphos + Cypermethrin) @ 2.0 ml/L of water) and highest (35.76 in 2018-19 and 42.53 in 2019-20) in control (T6) treatment. The lowest percent of head infestation of cabbage was also recorded in T5 treatment (14.03% in 2018-19 and 5.10% in 2019-20) and the highest in T6 treatment (27.61% in 2018-19 and 23.69% in 2019-20). The highest yield (33.40 t/ha in 2018-19 and 32.49 t/ha in 2019-20) was recorded from T5 treatment and the lowest (26.87 t/ha in 2018-19 and 24.78 t/ha in 2019-20) in control (T6) treatment in both the year. On an average, 16.55-20.33 flea beetle were captured in yellow sticky trap per week in both the year. The highest gross margin (438466 Tk.//ha in 2018-19 and 262366 Tk.//ha in 2019-20) was also observed in the T5 treatment in both the year and the lowest (342916 Tk.//ha in 2018-19 and 187666 Tk.//ha in 2019-20) in untreated control (T6) treatment. Finally, the results revealed that the treatment T5 was more profitable compared to other approaches as well as the highest crop yield with marginal benefit cost ratio.

Chickpea (Cicer arietinum L.) is the premier pulse crop of India, grown all over the country in Rabi season. It is a good source of essential amino acids such as tryptophan, methionine, cystiene and is the primary source of high quality protein for the largely vegetarian population of India. Heavy infestation of pest is one of the major reasons for low productivity of chickpea. Major pest of chickpea in sehore district is - pod borer, green semilooper, termite, cut worm etc. out of these insect gram pod borer is the major pest in chickpea. Single larva of the gram caterpillar Helicoverpa destroys 30-40 pods before its maturity. IPM module for the management of gram pod borer in chickpea – Summer deep ploughing + optimum seed rate +Bird purcher (50/ ha) + pheromone trap (10/ ha) + one spray of spinosad 45% SC at 40-45 DAS. During 2012-13 and 2013-14. IPM module are reduce average 55 per cent larval population of gram pod borer resulted 14.88 per cent enhanced the productivity of chickpea. Under IPM technology, the average productivity of chickpea is 1799 Kg/ha whereas in farmers practice, the average productivity of chickpea is 1566 Kg/ ha.

An experiment was carried out to evaluate the efficacy of integrated management practices over farmers’ practices against insect pest complex of green gram (Vigna radiata L. Wilczek) during kharif season in the ‘A-B’ Block Farm of Bidhan Chandra Krishi Viswavidyalaya in 2019. The results revealed that the incidence of all of the insect pests viz. whitefly, pulse aphid, jassid, flower thrips, gram pod borer, spotted pod borer, blue butterfly, plant bug and pod bug was recorded comparatively less in Integrated Pest Management (IPM) plot as compared to farmers’ practices. The seed yield of green gram was also recorded a higher (1382.22 kg ha-1) in plots treated with integrated approaches as compared to farmer’s practices (476.94 kg ha-1). IPM module recorded maximum cost benefit ratio along with higher gross return and net profit as against farmers’ practices.
