EFFICACY OF PLANT EXTRACTS AND TRICHODERMA VIRIDE AGAINST LEAF SPOT OF MAIZE CAUSED BY CURVULARIA LUNATA

Field screening was done under natural field conditions during rabi 2016- 17 to identify the sources of resistance in blackgram genotypes against leaf spot diseases caused by Corynespora cassiicola, Cercospora canascens. Out of sixteen blackgram genotypes evaluated only one genotype LBG 645 was mode[r]

Early blight of potato caused by Alternaria alternata is one of the major diseases causing considerable yield loss. Efficacy of bio-agents was studied and revealed the all four Trichoderma species significantly reduced the mycelial growth of the pathogen over the control by dual culture method. Sign[r]

Turcicum leaf blight (TLB) or Northern Corn Leaf Blight (NCLB) is a ubiquitous foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria. The TLB fungus survives through the winter on infected maize residue at the soil surface. As temperatures rise in[r]

The experiment was carried out at ZAHRS, UAHS, Shivamogga during 2016-2017 Kharif to study the character association and path analysis in respect of cured leaf yield and its contributing traits in F3 generation of FCV (Flue Cured Virginia) tobacco cross TB-70 x TB-102, The component characters viz.,[r]

Pomegranate (Punica granatum L.) is one of the important fruit crops belongs to the family Lythraceae. Nowadays most of the fields were infested by root knot nematode caused by Meloidogyne incognita which results in yellowing and stunting of plant further it affects the total yield of the crop.

The experiment “studies on collection and evaluation of genetic variability available in Amaranthus under Chhattisgarh plain condition” was conducted at Horticulture Research cum Instructional Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Rabi 2014-15.[r]

Three bio-agents i.e. Trichoderma viride, Trichoderma harzianum and Trichoderma asperellum were evaluated against M.musicola under in vitro condition. Culture disc of fungal bio-agents and pathogen were taken from the growing cultures and transferred to PDA contained in 80 mm petridishes on opposite[r]

Rice is an important food crop in India. One of the major constraints of rice production is that it is prone to several diseases. Among them brown leaf spot disease has been reported to occur in all rice growing regions. A study was conducted to determine the performance of fifty paddy varieties aga[r]

The present study was conducted to assess the antimicrobial potential and phytochemical analysis of Aloe vera (Aloe barbadensis Miller) leaves extracts.The extracts were prepared by the sequential cold maceration method by using hexane, ethyl acetate, methanol and distilled water as a solvent.
