The Standing Committee on Chemicals and Fertilizers presented its report on ‘Insecticides and Pesticides – Promotion and Development including Safe Usage – Licensing Regime for Insecticides’ on December 19, 2023. Pesticides are broadly of four types: insecticides, fungicides, herbicides, and bio-pesticides. Herbicides kill/control the growth of weeds, and have the …
One of the significant areas in which pesticide residue analysis differs significantly from macro-analysis is that of contamination and interference. Trace amounts of contamination in the final samples used for the determination stage of the method can give rise to errors such as false positive or false negative results or …
The effect of an organophosphorus (OP) insecticide, methyl parathion on the behaviour of a freshwater air breathing teleost fish, the Climbing perch, Anabas testudineus was studied. The breathing rate, rate of feeding, performance of sustained swimming behaviour against water current and the learning ability were severely curtailed in the fish …
A field experiment conducted at the College of Agriculture, CSKHPKV, Palampur, H.P. during 1999-2000 revealed that the synthetic pyrethroid treatments viz., deltamethrin, cypermethrin and fenvalerate gave significantly less fruit infestation of cucurbit fruit fly, Bactrocera cucurbitae Coq. upto 14 days of spray on summer squash compared to malathion.
This study assesses the role of the blue-green algal species present in the soil in the dissipation of endosulfan and its metabolites in the soil environment. Two Anabaena species, Anabaena sp. PCC 7120 and Anabaena flos-aquae, were used in this study. Anabaena sp. PCC 7120 produced three principal biotransformation compounds, …
Oral administration of the insecticide endosulfan (2 mg/kg per day) for 90 days in immature male rats resulted in an inhibition of pole-climbing escape response to electric shock (unconditioned) and avoidance response to buzzer (conditioned). These responses reflect respectively their learning and memory processes. The escape response but not the …
THE INDIAN cotton crop, already attacked by several insects resistant to most insecticides, is now falling prey to a new insect -- the American serpentine leaf-miner. Scientists suspect this new threat, a native of southern USA, entered the country in 1990-91, probably from Kenya or Europe, along with chrysanthemum cuttings. …
The insecticide endosulfan, has been widely used for the control of crop pests in the field of agriculture. Although no mutagenic, teratogenic or carcinogenicity information is available on this insecticide, there are several reports concerning its toxicity after oral as well as from repeated administration in mice, rats and rabbits.
