A study was conducted to identify the suitable strategies for effective mitigation of stalk rot. Stalk rot in maize caused by Fusarium moniliforme has been a concern in majority of maize growing areas. Their ability to parasitize the pathogens by starvation, encourage growth of the plants by acting as defense agents and adoptability to different kinds of climatic fluctuations makes them more suitable for engaging against the stalk rot of maize. Bacterial stalk rot of maize caused by Dickeya zeae previously known as E. chrysanthemi pv. Stalk and crown rot diseases can cause initial symptoms that are easily misdiagnosed. Fusarium graminearum is a destructive pathogen of cereals that can cause stalk rot in maize. The bacterium prefers high temperature and moisture for their growth result is plant toppled down within week. Bacterial stalk rot of maize caused by Dickeya zeae previously known as E. chrysanthemi pv. Diplodia ear rot is a notable maize disease in South Africa. <>>>/Contents 5 0 R >>endobj
The disease is more prevalent in rainy season in India. The pooled disease incidence was 7.10 per cent. Post flowering stalk rot: Cephalosporium wilt (Black bundle disease and late wilt) Causal organism: … Symptoms of Fusarium stalk rot include rotting at roots, crown and lower internodes. The pooled yield was 6056kg/ha with a cost benefit ratio of 2.09. Five antibacterial chemicals viz., stable bleaching powder, streptocycline, cristocycline, blitox, kocide and one bioagent (Pseudomonas fluorescens) were evaluated zeaehave economic importance of reduced crop yield up to 98.8%. 3 0 obj
zeae have economic importance of reduced crop yield up to 98.8%. Corn, Zea mays, is an annual grass in the family Poaceae and is a staple food crop grown all over the world. The treatment was statistically significant over other treatments which also recorded highest grain yield of 6044kg/h during 2014, 6067kg/h during 2015. %����
The earliest visible symptoms are the discoloration or rapid death of the upper leaves or whole plant (Figures 1a and 1b).Affected plants may occur in patches where stress occurred or seemingly randomly scattered. The results once again reconfirm the beneficial characters of T. viride and P. fluorescensi against the pathogenic microbes in soil. The rotting extends from infected roots to the stalk and causes premature drying, stalk breakage and ear dropping, thus significantly reducing maize yield (Sharma et al., 1993) [9]. There are no hybrids resistant to this disease. <>endobj

stalk rot symptoms are observed during post flowering and pre-harvest stage (Lal and Singh, 1984) [5]. Stalk rot results in yield losses due to impaired grain filling, premature senescence, and lodging, which limits production and harvesting of ears. Since 1970, anthracnose stalk rot … Stalk rot in maize caused by Fusarium moniliforme has been a concern in majority of maize growing areas. There are no hybrids resistant to this disease.

In untreated control stalk rot was 31.33 per cent during 2014, 42.10 per cent during 2015 and grain of 3378kg/h and 3444kg/h respectively during 2014 and 2015 with a pooled yield of 3411kg/h and cost benefit ratio of 0.78, the lowest among all.

Biocontrol agents Among the different treatments, seed treatment with T. viride and P. fluorescens at 2.5g each/kg of seed and soil application of 1.25kg/h each fortified with 250kg of FYM had lowest stalk rot of 6.07 per cent during 2014 and 8.13 per cent during 2015. Apart from causing severe damage to the crop, it can also produce a potentially fatal mycotoxicosis in cattle and sheep. Seed treatment with Mancozeb 50% + Carbendazim 25% WS (sprint) 1g/kg & 2g/kg and Thiram 75WP (1g/kg) had more disease compared to biocontrol treated plots.
