Plant foliage are widely utilized as cattle feed, especially vegetables due to their rich nutritive and fiber content. Brinjal, the wide cultivated vegetable crop for its fruits, which is a major vegetarian food dish, leaves lot of plant material to be destroyed, which is utilized as livestock feed in some parts of the world. Brinjal intake a huge pesticide load to withstand the enormous insects, diseases and nematodes that damage the crop, which leaves the residues to accumulate in the plant parts including the foliage, which can be detrimental to the cattle that feed on them. In this regard, the current research was conducted to investigate the persistence behaviour and dissipation dynamics of a carbamate chemical, carbosulfan, which is capable to manage the major brinjal insect pests such as shoot and fruit borer. The results revealed that the residues reached below the detectable level (BDL) at 14 day after three rounds of spraying of carbosulfan at the recommended dose of 250g a.i.ha-1, which was 2.071 and 5.09mg g-1 at the higher doses of 500 and 1000g a.i.ha-1 respectively. However, those residues reached below the detectable level on 21st day after spraying at all levels of application of the chemical. The residues were below the maximum permissible residue limit (MRL) of 0.1μg g-1 at the recommended dose of 250 g ai ha-1 making it a suitable insecticide for managing brinjal pests without any risk as cattle feed.
