Biodegradable multifunctional polymeric membranes based on poly(L-lactic acid), PLLA, and metal-organic framework compounds (MOFs) were developed. PLLA with and without the addition of 5 wt % MOF was melt compounded in a microextruder, and the solubility parameters, water sorption isotherm, and permeability coefficients to oxygen, carbon dioxide, water, ethyl acetate, hexane, and cyclohexane were determined. The sorption capacity of the PLLA-MOFcomposite films increased up to 2-fold at each relative humidity to which it was exposed when compared with the PLLA films. The sorption and desorption curves of the PLLA-MOF films show hysteresis. The presence of MOF in the composite films did not significantly modify the permeability coefficients of the PLLA-MOF films. © 2011 American Chemical Society. Source

In AMMI analysis environment main effect and genotype x location interaction were found significant. Significant differences in maize hybrids were observed for grain yield among the locations over the years both under stress and non-stress conditions. Among the four interaction principal component axes (IPCA) of GGE biplot, first two IPCA were significant explaining 75.89% variation. Hybrid, KDMI-15 x NEI-9202-B was found superior among all the hybrids over checks over all the locations. Other hybrids viz., CM-111 x HYD SEL-15 and CI-4 x NEI-9202-B exhibited almost no interaction with the environments convincing the reliability of their performance. The hybrids viz., KDMI-15 x NEI-9208-B, CM-111 x HYD SEL-17, 900M, CML-446 x HYD SEL-4, CI-4 x HYD SEL-17, HYD SEL-7 x KDMI-15 and HYD SEL-15 x HYD SEL-17 were most responsive. © 2015, Indian Society of Genetics and Plant Breeding.

In Jan and Feb 2015, the tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), was found to have entered and established in the Malnad and Hyderabad-Karnataka Regions of Karnataka, India, where it is infesting tomato and potato crops. To our knowledge, this is the first record of T. absoluta in these regions of India. The incidence recorded appears to be comparatively small at some locations, but this damaging insect may spread to other regions of India and cause serious crop loss in the future. Probably, the introduced populations are resistant to various insecticides, and management of insecticideresistant populations poses additional problems. © 2015, BioOne. All rights reserved. Source

Three biocontrol agents such as Trichoderma harizianum, Pseudomonas fluorescens and Bacillus subtilis were isolated from safflower rhizosphere soil and tested individually for their effectiveness in controlling root-rot of safflower. Talc based formulations were prepared and treated the seeds at different concentrations for assessing their ability to induce plant growth and in turn control root-rot disease. Among bioagents, P. fluorescens and T. harzianum (10g/kg) proved to be effective in controlling disease under laboratory, greenhouse and field conditions. The efficacy of these biocontrol agents are equivalent to the standard fungicide Bavistin (Carbedazim). Other than direct action of these biocontrol agents triggered defense related enzymes involved in phenyl proponoid pathways and phenols. Higher activity of peroxidase, phenylalanine ammonia-lyase, chitinase, polyphenol oxidase and β-1,3-glucanase was observed in P. fluorescens and T. harzianum treated safflower plants after challenge inoculation with M. phaseolina. Seed treatment with these biocontrol agents enhanced the seed germination and growth parameters against root-rot disease and they also induced systemic resistance and/or physiological changes leading to plant defense mechanisms.

One hundred and forty four germaplasms of sunflower (Helianthus annuus L) were screened under field condition. The experiment was conducted at GKVK ,UAS, Bangalore during the year 2007-08. The trial was conducted for identifying the resistant lines against Ieafhopper Amrasca biguttula biguttula (Ishida). Among the one hundred and fourty four sunflower germplasm lines Acc No 1223, 1210, 1198, 1149, 89-B, Ace No 256, and HAM 176 were comparatively superior to the check Morden with respect to their resistance to Ieafhopper. The entries of HAM series which were obtained by crossing Morden and Helianthus argophyllus that were having glabrous and thick leaves were promising against Ieafhopper. Source
