“…ha -1 at 2-3 leaf stage of weeds (W 4 ), might be due to the reason that lower weed population had provided favourable environment to the crop and least crop weed competition, which resulted in higher photosynthetic accumulation rate and better translocation to the sink as compared to weedy check (W 9 ). Similar results were reported by Kumar et al, (2015) and Singh et al, (2016). Significantly higher seed yield and haulm yield recorded with hand weeding at 20 and 40 DAS (W 8 ) and pendimethalin 30%EC + imazethapyr 2% EC @ 1.0 kg a.i.…”

“…The combination of imazethapyr + pendimethalin (RM 1000 g/ha PE) proved its supremacy over all other treatments to control monocot (4.74 weeds/m 2 ) and total weeds (5.62 weeds/m 2 ) and imazethapyr + imazamox (RM) 80 g/ha PoE (1.44 weeds/m 2 ) found superior to control dicot weeds over weedy check for each category. Singh et al (2016) also reported the same trend of result in black gram. Kushwah and Vyas (2006) reported that imazethapyr applied at 75 g/ha was effective against both monocot and dicot weeds and was at par with one hand weeding carried out at 20 DAS, however, it was more effective against grassy weeds.…”

A systemic field study on bioefficacy of different herbicides in greengram (Vigna radiata L.) under irrigated condition of Gujarat and its residual effect on succeeding mustard crop was conducted during Kharif 2014 and 2015 at AAU, Anand. Among the tested options, hand hoeing at 20 and 40 days after sowing (DAS) and pre-emergence (PE) application of imazethapyr + pendimethalin ready mix (RM) at 1000 g/ha proved their supremacy in achieving highest seed yield (1.45 and 1.43 t/ha) with highest B:C of 2.91 & 2.88, respectively. These treatments provided season long control of weeds with the weed control efficiency (WCE) of 93% and 89%, respectively. Moreover, post-emergence (PoE) application of imazethapyr 70 and 80 g/ha or imazethapyr + imazamox ready mix (RM) 80 g/ha provided excellent WCE of more than 85%, but posed their negative impact on symbiotic parameters such as nodule number, plant dry weight and secured lower net return. Treatment receiving pre-emergence application of imazethapyr 80 g/ha was only found superior to achieve all profits with low input cost but did not control weeds effectively. Additionally, imazethapyr and its ready mix combination irrespective of dose did not show any residual effect to succeeding mustard crop.

“…Imazethapyr 2% + pendimethalin 30% EC is the one pre-mix herbicide mixture, containing two herbicides with different mode of action available in the market for weed control in pulses. Singh et al (2016b) reported that pre-emergence application of pendimethalin @ 1000 g ha -1 or premix combination of imazethapyr + pendimethalin at doses, 800, 900 and 1000 g/ha were found more effective for weed control in black gram. Among the three doses, the higher doses (900 and 1000 g ha -1 ) were found more effective in reducing the density and dry weight of weeds and recorded higher weed control efficiency and yield.…”

Weed Management in Pulses: A Review

Pulses are the important crop after cereals and is the cheapest source of dietary protein. After the Green revolution, the production of pulses in India remain stagnant over the years due to various biotic and abiotic stresses. Among the various biotic stresses, weeds are the major one which causes severe yield loss in pulses. Due to initial slow growth of pulses, weeds emerge first and gain competitive advantage over the crop and exhibit smothering effect on crop. Moreover, major area of pulses (84 per cent) are under rainfed condition and grown in combination with non-legume crop. As a result, pulses are subjected to various types of biotic and abiotic stresses. Weeds besides causing direct loss in yield also hinder farm activities and serve as alternate host to many pests. Weed management in pulses is essential to bring the weeds below the threshold level to maximize the seed yield and quality. The literature regarding the importance of weed management in pulses, weed flora, critical period of crop weed competition and different weed management methods of weed control are collected and presented in this paper.Weeds are the predominant biological constraint in pulse production due to the slow initial growth of the crop. Strategies’ of weed management depends on the weed competition, types of weeds present and weed control method adopted. In general, critical period of weed competition for short duration pulses is up to 30 days and for long duration pulse crops it is up to 60 days. The major three types of weeds viz., grasses, broad leaved weeds and sedges were found in association with pulses. Intensity of weed infestation varies with agroecological conditions and crop management practices followed. A system approach is necessary to maintain the weed population below the economic threshold level thereby reducing the yield loss. Integrated weed management (IWM) which has been proved to be more effective than any single method in alleviating the buildup of weeds in pulse crop.
