Increase in productivity is directly related with increase pesticide consumption. So there is a strong desire to use "greener" chemistry to produce more toxicologically and environmentally benign pesticides and natural products. In this present study, a comparison was made to evaluate the phytotoxicity potential of first cleanup fractions obtained from sequentially extracted solvent (ethyl-acetate, methanol) extracts of Parthenium hysterophorus L. (aerial parts) in vitro through bench-top seed germination assay (Vigna radiata L.). One-way analysis of variance (ANOVA) followed by Duncan's multiple range test (DMRT) were done for statistical analysis of the data. The study reveals that germination, growth and vigour was significantly (P<0.05) reduced by ethyl-acetate and methanol fractions. A significant changes in soluble and insoluble sugar content, protein, amino acid content and cellular metabolic activity was aslo observed by 1F3, 1F4, 1F6, and 1F9 fractions. The present study concluded that phytotoxicity of four fractions (1F3, 1F4, 1F6, and 1F9) from ethylacetate and methanolic crude extracts of Parthenium hysterophorus could be exploited as potential bioherbicide for future weed management programme and the development of bioherbicide for commercial use.

There is a worldwide search for the safe, effective and eco-friendly compounds of plant origin to combat the weed species and other pests which are responsible for the great impact on the growth and productivity of agricultural crops. In this present study, a comparison was made to evaluate the phytotoxicity potential of sequentially extracted solvent (hexane, ethyl-acetate, methanol) extracts of Parthenium hysterophorus L. (aerial parts) in vitro through bench-top seed germination assay (Vigna radiata L.). One-way analysis of variance (ANOVA) followed by Duncan's multiple range test (DMRT) were done for statistical analysis of the data.

Brinjal (Solanum melongena L.) suffers from the attack of various pests throughout its cropping season. Different insecticides are used to control these pest infestations. The application of these insecticides on brinjal plants may have an effect on its quality and nutritional parameters of fruit samples. In the present study effect of three different insecticides viz. Triazophos 40% E.C Carbaryl 50% W.D.P, Cypermethrin 10% E.C, and Azadiractin 10000 ppm formulation belonging to different groups namely Organophosphate, Carbamate, Synthetic pyrethroids and Botanical insecticide on brinjal fruit quality, nutritional parameters and Total antioxidant capacity (TAC) were assessed in field conditions. The results showed that different insecticide at field application dose showed minute insignificant variation in fruit nutritional and total antioxidant activity parameters in comparison to the control samples. The fruit quality parameters also showed minute variation in comparison to the control except in the case of Triazophos treated samples which showed significant variation (p<0.05) in titrable acidity, total soluble sugar content and crude protein.
