“…Among different pre-emergence herbicides, weed control efficiency of isoproturon @ 0.5 kg a.i./ha was significantly high at 25 DAS and it was on par with bensulfuron methyl + pretilachlor 0.198 kg a.i./ha (Table 1). Banu et al (2016) also reported similar results in transplanted finger millet. However, at 50 DAS, weed control efficiency of preemergence herbicides alone has decreased significantly and at the same time, inclusion of inter cultivation at 30 DAS in addition topre-emergence herbicides has significantly increased weed control efficiency.…”

A Field experiment was carried out during two consecutive years (2016-17) at Agricultural Research Station, Vizianagaram, Andhra Pradesh to find out the best weed management practice for profitable production of direct-seeded finger millet (Eleusine coracana L.) under rainfed condition. Two intercultural operations (IC) with hand weeding at 20 and 40 DAS was found effective in reducing weed density and dry weight up to 50 DAS, increasing yield attributes and economic yield. Among the herbicidal treatments, pre-emergence application of isoproturon at 0.50 kg a.i./ha was found superior to reduce the weed density up to 25 DAS. However, application of pre-emergence herbicide alone is not sufficient for effective weed control throughout the critical period of crop-weed competition. Integration of one IC at 30 DAS in addition to pre-emergence application of isoproturon at 0.50 kg a.i./ha was identified as the best weed management practice as it attained minimum weed index (6.4%) and maximum B:C ratio (1.88), weed control efficiency (WCE) (89.7% and 96.9% at 25 and 50 DAS, respectively), herbicide efficiency index (92.5%), growth and yield attributes, grain yield (2230 kg/ha) and straw yield (6512 kg/ha). However, it remained statistically on par with bensulfuron methyl + pretilachlor 0.198 kg a.i. /ha as PE + IC at 30 DAS.

“…In drill sown finger millet, lower weed density, dry weight and higher weed control efficiency were recorded under PE bensulfuron methyl + pretilachlor at 10 kg/ha (Kumar et al, 2015) [17] . Banu et al (2016) [4] found that in finger millet, PE bensulfuron methyl + pretilachlor at 660 g/ha recorded higher weed control efficiency. Kujur et al (2019) [16] reported that higher herbicide use efficiency was owing to superior weed control both in terms of reduction in density and biomass of weeds.…”

“…bulbosus among sedges, Sesamum ekamberi, Trianthema portulacastrum and Portulaca oleracea among broad leaved weeds. Banu et al (2016) [4] reported that predominant weed flora observed in the experimental field of GKVK, Bengaluru during investigation includes Dactyloctenium aegyptium, Cynodon dactylon, Digitaria marginata, Panicum miliacea, Eleusine indica and Echinochloa colona among grasses, Portulaca oleracea, Parthenium hysterophorus, Ageratum conyzoides, Commelina benghalensis, Mollugo disticha, Phyllanthus niruri, Alternanthra spp, Sida acuta, Sida cardifolia, Amaranthus viridis, Miomosa pudica, Bidens spilosa, Achyranthes aspera among broad leaved weeds and Cyperus rotundus and Cyperus esculentus were major sedges in transplanted finger millet system. Chavan et al (2017) [8] found that in Kharif finger millet major weeds observed were Cynodon dactylon, Cyperus rotundus, Eragrostis coarctata and Eragrostis minor among grasses and Amaranthus viridis, Ageratum conyzoides, Commelina benghalensis, Celosia argentea, Convolvulus arvensis, Euphorbia hirta, Portulaca oleracea and Tridax procumbens among broad leaved weeds.…”

Finger millet production requires a lot of labour, particularly for weed management practices. Weed spectrum depends on the efficiency of the finger millet ecosystem and control measures practiced. A most possible way for controlling weeds is by manipulating the cropping system and making conditions more favourable for crop growth and unfavourable for weed growth. Weeds belong to various groups viz., grasses, sedges and broad leaved weeds (BLW) are associated in finger millet cultivation. The weed management practices are limited to five options viz., preventive, cultural, mechanical, chemical and biological methods. The common weed control method used is the hand weeding which is time consuming and also difficult to control weeds. Although manual weeding is effective, it is costly, tedious and time consuming. Fischer et al. (2001) reported that the increasing cost of labour have made these methods uneconomical for weed control. Since single method is not able to control all weeds up to desired level, integration of weed management practices can be an effective weed control strategy to achieve greater weed control efficiency and increase overall benefit of finger millet cultivation.

“…AICRPSM [70] stated that pre-emergence application of Oxadiargyl @ 70 gm/ha or Pretilachlor @0.75 kg/ha was effective in weed management of foxtail millet. To obtain effective broad spectrum weed control in Finger millet, Oxadiargyl @ 0.08 kg/ha at 3 DAS fb Ethoxysulfuron @ 0.012 kg/ha at 30 DAS, Butachlor @ 0.75 kg/ha as Pre-emergence, Isoproturon as Pre-emergence fb 2,4-D Na salt as Post-emergence each @ 0.5 kg/ha, Bensulfuronmethyl + pretilachlor @ 0.06 + 0.60 kg/ha as Pre-emergence (2 DAT) are recommended (Shubhashree and Sowmyalatha [13], Dhanapal et al [87] and Banu et al [88]). For weed control in Kodomillet, Bensulfuronmethyl + pretilachlor @ 0.33 kg/ha as Pre-emergence/early post-emergence against wide range of weeds and Bispyribacsodium @ 0.02 kg/ha as post-emergence (20 DAT) against grassy weeds are recommended (Lekhana et al [17], Jawahar et al [19] and Chanu et al [89]).…”

Presently, agriculture is facing tremendous problem due to climate change and global warming. To ensure food and nutritional security at national level, there is an immediate need to promote the cultivation of millets as millets are considered climate smart and nature friendly crops because of high nutritive value and can withstand under warm and drought conditions with short life, low external inputs requirement, tolerance to water and temperatures stress. Ten millet crops have been declared as ‘Nutri Cereals’ which include three major millets i.e., pearl millet, sorghum and finger millet; five minor millets i.e. foxtail millet, proso millet, kodo millet, barnyard millet, little millet; and two pseudo millets i.e. kuttu (buckwheat) and amaranthus. Due to sluggish growth in initial phases of life, millets proved relatively poor competitors against weeds. Manual weeding is the most commonly adopted for weed control in millets. But the non-availability of labour and ever-increasing labour wages have compelled the farmers to seek alternate method of weed management. Herbicide use is the most viable method of weed control but their continuous and excessive use is not advisable due to its ill effects on environment and development of herbicide resistance in weeds. Very limited options are available in literature for weed control in minor millets. Thus, integrated weed management practices should be followed on site and time specific basis for effective and efficient weed management in minor millets. For integrated weed management in minor millets, 2-3 times inter-cultivation and 1-2 time hand weeding during initial 25 days after sowing in addition to pre-emergence spray with Isoproturon @ 0.5 -1.0 kg a.i./ha and post emergence spray of 2, 4-D sodium salt @ 0.75-1.0 kg a.i./ha at 20-25 days after sowing should be done for effective weed control.
