A field study was conducted to evaluate one combination of seed treatment with imidacloprid (Confidor 70 WS) and spray with detergent and for insecticide sprays: imidacloprid (Confidor 20% SL), acetamiprid (Acelan 20% SL), thiomethoxam (Actara 25 WG) and acephate (Commando 75 SP), against sucking insect pests on mungbean, Vigna radiata (L.) at Arid Zone Research Institute (AZRI), Bhakkar during 2012. All the treatments showed a significant difference with one another, regarding their effectiveness. The application of insecticide sprays immediately enhanced the mortality of the pests, whereas, the effect of seed-treatment and detergent did not show distinctive effect on the pests' population. Imidacloprid and thiomethoxam resulted in a maximum mortality of the jassid, followed by acetamiprid. While in case of whitefly, imidacloprid was the most effective and resulted in a minimum population followed by acetamiprid. Acephate resulted in the maximum control of thrips and was found the most effective insecticide, followed by acetamiprid.

The present study was undertaken to study the relative efficacy and economics of seed treatment and newer insecticides against sucking and borer pests of mungbean during summer 2015 and 2016. Seed treatment with imidacloprid 48 FS @ 5 ml/ kg seed and spraying of thiamethoxam 25 WG @ 50 g a.i./ ha was highly effective against sucking pests like whiteflies, aphids and thrips in mungbean. Seed treatment with imidacloprid 48 FS @ 5 ml/ kg seed and insecticides like indoxacarb14.5 SC @ 65g a.i./ha was highly effective against pod borers like Maruca vitrata (Geyer) in mungbean. Seed treatment with imidacloprid 48 FS @ 5 ml/ kg seed and spraying of spinosad 45 SC @ 73 g a.i./ ha was also effective against thrips and pod borers in mungbean. Seed treatment with imidacloprid 48 FS @ 5ml/kg seed and spraying of indoxacarb 14.5 SC @ 65g a.i./ha recorded highest yield (8.9 quintal/ha), highest net return over control (Rs 27,850/-) and highest B:C ratio (2.86), so a better management option for f...

A field experiment was conducted to find out the effective dose of some newer insecticides for the management of sucking insect pests of mungbean viz., whitefly (Bemisia tabaci), jassid (Empoasca kerri) and thrips (Caliothrips indicus). The treatments of experiment were Diafenthiuron 50 WP @ 187.5g a.i./ha, Diafenthiuron 50 WP @ 250g a.i./ha, Diafenthiuron 50 WP @ 312.5g a.i./ha, Spiromesifen 240 SC @ 90 g a.i./ha, Spiromesifen 240 SC @ 120g a.i./ha, Spiromesifen 240 SC @ 150g a.i./ha, seed treatment with Thiamethoxam 70 WS + Thiomethoxam 25 WG @ 5 g/kg seed + 25.0 g a.i./ha, Thiamethoxam 25 WG (Std. Check) @ 25g a.i./ha and Triazophos 40 EC (Std. Check) @ 500g a.i./ha. The results of experiment revealed that among the tested insecticides, the treatment T3 (Diafenthiuron 50 WP @ 312.5 g a.i./ha) was found most effective resulting in 85.9% and 77.8% reduction of whitefly and thrips population respectively. The treatment T5 (Spiromesifen 240 SC@ 120 ml a.i./ha) was found most effective against jassid resulting in 77.5% reduction of population.
The research studies were conducted to evaluate the impact of various concentrations of insecticide (methamedophos) on the insect control, seed yield and economics of mungbean at the research Farm of Arid Zone Research Institute, Dera Ismail Khan during two years viz. 2004 and 2005. The treatments consisted of 500, 750, 1000, 1250 mL ha -1 of methamedophos including control. The data revealed that generally all the concentration levels of methamedophos positively controlled the short horn grass hopper attack (reduced its infestation level) and affected the yield components and seed yield kg ha -1 except maturity but the above parameters were significantly increased as 25% branches plant -1 , 42% pod plant -1 , 15% grain pod -1 , 8.3 g seed weight and 48% seed yield over control plots @ 1000 mL ha -1 during kharif 2004, although it did not differ significantly with highest level of 1250 mL ha -1 . During kharif 2005 the said level of concentration @ 1000 mL ha -1 gave significant increase of 29% in plant height, 106% branches plant -1 , 45% pod plant -1 , 12% grain pod -1 , 9.8% g seed weight and 45% seed yield kg ha -1 over control. Minimum insect infestation was observed when methamedophos was applied @ 1000 mL to 1250 mL ha -1 as compared to control that showed maximum infestation. The highest cost benefit ratio of Rs. 1:16 and 1:10 was recorded @ 1000 mL ha -1 of methamedophos during both the years, respectively. These results suggest that methamedophos @ 1000 mL ha -1 is the best economical rate for getting maximum insect control, seed yield and net crop return.

Field study was carried out at Bangladesh Agricultural Research Institute (BARI) farm during March to August 2005 to find out the most appropriate management practices against thrips of mungbean. The experiment consisted of seven treatments of various management practices. It was laid out in Randomized Complete Block Design (RCBD) with four replications. The incidence of this pest was first noticed during vegetative and flowering stage. The infestation rate was highest in reproductive stage. Application of Furadan 5G as a seed treatment gave the maximum yield (950.5 kg-ha). On the other hand, minimum yield was found in control treatment. Two times application of Shobicron 425 EC also gave the satisfactory result but it was not economically viable. Neem oil with Trix gave the significant result in comparison with other treatments and it may be environmentally friendly.

Integrated Biological Technology to Control Mungbean Pests and Diseases
Indonesian Journal of Agricultural Science, 2021
The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9....

Field trials were conducted during the 2018 and 2019 cropping seasons at Okigwe in Imo State Nigeria to evaluate the efficacy of Neem (Azadirachta indica), Occimum gratissimum, Chromolaena odorata, and Vernonia amygdalina leaf extracts for the control of insect pests of mungbean variety NM-92. The experimental design was a Randomized Complete Block Design (RCBD) with five treatments and four replications. Results obtained indicated that A. indica and O. gratissimum significantly (P<0.05) reduced the population of Chrysolagria spp and Megalurothrips sjostedti when compared with the control in the 2018 and 2019 cropping seasons. There was no significant difference in the population of Zonocerus variegatus, Ootheca mutabilis, Maruca vitrata, Clavigralla tomentosicollis and Aphis craccivora. A. indica and O. gratissimum performed best in both dry pod weight and dry grain weight in both cropping seasons when compared with other treatments such as Chromolaena odorata and Vernonia amygdalina by recording a significantly higher dry pod weight and dry grain weight. A. indica and O. gratissimum leaf extracts can be used to control Chrysolagria spp and M. sjostedti on mungbean applied at two weeks interval after crop emergence. The efficacy of the A. indica and O. gratissimum in reducing the insect damage on the mungbean could be attributed to their respective active ingredients.

Mungbean yellow mosaic virus (MYMV) is an important constraint in successful production of mungbean (Vigna radiata L.) in many countries, including Pakistan. The MYMV spreads by insect vector whitefly (Bemisia tabaci Gennadius). The use of resistant cultivars is the most effective management tactics for MYMV. Twenty mungbean varieties/lines were screened against insect vector of MYMV under field condition in the current study. Resistance levels for varieties/lines were assessed through visual scoring of typical disease symptoms. Furthermore, the impacts of two insecticides ‘Imidacloprid’ and ‘Thiamethoxam’ and two plant extracts, i.e., neem (Azadirachta indica), and Eucalyptus (Eucalyptus camaldulensis) were tested on the suppression of whitefly. Field screening indicated that none of the tested varieties/lines proved immune/highly resistant, while significant variations were recorded among varieties/lines for resistance level. All varieties/lines were systemically infected with MYM...
