Abstract

In cultivation of button mushroom [Agaricus bisporus (Lange) Imbach], casing layer that is nutritionally deficient to compost is believed to trigger the fruit body formation and this is conducted by the bacterial community residing in casing layer. Therefore, relationship between different concentrations (1 x 104, 1 x 106, 1 x 108, 1 x 1010, 1 x 1012) of bacterial inoculants (Pseudomonas putida) and yield of Agaricus bisporus were determined. Available data showed a significant difference in yield in respect to concentration of bacterial inoculant added. In addition, concentration 1x 108cfu/ml was found to be high yielding concentration, which took minimum case run period together with higher biological efficiency compared to other.

Abstract

An experiment was conducted to evaluate the effect of bio agents (Trichoderma harzianum and Pseudomonas fluorescens) and fungicides (mancozeb) against earlyblight of tomato caused by Alternaria solani (Ell. and Mart.) at the experimental field of Department of Plant Protection, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during Rabi Season (2013-2014). Seven treatments including control with three replications were taken up using RBD. The treatments comprised of seed treatment and foliar spray (once and twice) of bio-agents Trichoderma harzianum and Pseudomonas fluorescens while fungicide taken up was mancozeband Control (spray of plain water) was applied. Observation for percent disease intensity was recorded at 70, 90 and 105 days after transplanting. Minimum disease intensity was recorded in mancozeb with twofoliar spray (15.43%, 17.90% and 20.47%, respectively) as compared to control which recorded maximum disease intensity (25.50%, 33.47%, and 48.73%, respectively).The bio agents Trichoderma harzianum and Pseudomonas fluorescens (seed treatment + two foliar spray) were also effective in reducing the disease intensity.

Abstract

An experiment was conducted to evaluate the effect of bio agents (Trichoderma harzianum and Pseudomonas fluorescens) and fungicides (mancozeb) against early blight of potato caused by Alternariasolani (Ell. and Mart.) at the experimental field of Department of Plant Protection, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during Rabi Season of 2013-2014. Seven treatment including control with three replications were taken up using RBD. The treatments comprised of seed treatment and foliar spray (once and twice) of bio agents Trichoderma harzianum and Pseudomonas fluorescens while fungicide taken up was mancozeb and control (spray of plain water) was applied. Observation for per cent disease intensity was recorded at 60 and 80 days after sowing. Lowest disease intensity was recorded in mancozeb (15.07% and 18.40%, respectively) as compared to control which recorded highest disease intensity (20.91% and 33.80%, respectively).Mancozeb not only reduced disease intensity but also recorded highest yield (253.00 q/ha) as compared to control which recorded 157.83 q/ha.The bio agents Trichoderma harzianum and Pseudomonas fluorescens (seed treatment +foliar spray) were also effective in reducing the disease intensity and increasing tuber yield.

Abstract

The investigation was conducted with 8 Treatments:- Dimethoate 30 EC @ 0.03 per cent, Abamectin 1.8 EC @ 0.003 per cent, Spinosad 45 SC @ 0.03 per cent, Acetamiprid 20 SP @ 0.04 per cent, Imidacloprid 17.8 SL @ 0.005 per cent,Neem oil 2 per cent, NSKE 5 per cent and control (water spray) on citrus leaf minor. Such treatments were arranged in statistical design RBD with three replications. In overall, cumulative effect of 3 applications of all the treatments T₅ Abamectin 1.8 EC (0.003%) recorded lowest (7.66%) leaves infestation of leaf minor and found at par with T₂ Spinosad 45 SC (0.03%) i.e.8.42 per cent leaf infested. The next best effective treatments, T₄ Acetamiprid 20 SP (0.04%), T₃ Imidacloprid 17.8 SL (0.005%), T₁ Dimethoate 30 per cent (0.03%), T₆ Neem oil (2%) and T₇ NSKE (5%) with infestesion of 9.37 per cent, 10.46 per cent,13.08 per cent, 14.63 per cent and 15.21 per cent, respectively and these treatments groups were at par with each other. Maximum infestation of leaf minor was noticed in control (water spray) is 24.75 per cent.

Abstract

Gram pod borer (Helicoverpa armigera) is the most serious pest responsible for higher yield losses in chickpea, cotton and red gram in India. Helicoverpa armigera is the major pest of many crops and considered as the main pest of chickpea. No plant seems to be strong enough to avoid attack of Helicoverpa armigera in affected field. Larvae of Helicoverpa armigera (Hubner) were collected from the nearby fields of chickpea. Present study was conducted to determine the susceptibility of Helicoverpa armigera (Hubner) for indigenous products and insecticide at various treatment. Seven treatments and five replication in indigenous products along with four treatment and five replication were taken up for the experiments. The data collected was analyzed using CRD design. Mortality of third instar Helicoverpa armigera (Hubner) was evalatued using tobacco leaf extract 10 per cent, Neem seed kernel extract 10 per cent, Neem leaf extract 10 per cent, cow urine 10 per cent, cow dung 10 per cent and cow urine + cow dung 5 per cent and plain water as control. The result revealed that T₁= tobacco leaf extract 10 per cent gave minimum mortality (7.37%) and T₆= Cow urine + cow dung 5 per cent gave maximum mortality (26.32%) third instar larvae Helicoverpa armigera (Hubner) and Mortality of third instar of Helicoverpa armigera was evaluated using Quinolphos 0.01 per cent, Cypermethrin 0.01 per cent and Chlorpyrifos 0.01 per cent and plain water as control. The results revealed that T₂= Cypermethrin gave minimum mortality (48.91%) and T₃ = Chlorpyrifos gave maximum mortality (77.66) third instar larvae of Helicoverpa armigera.
