Cauliflower is one of the most important vegetables of India. Cauliflower plant belongs to the family cruciferae and consumed as a vegetable in curries, soups, salads and pickles. India is the second largest producer of cauliflower after China and produces 4.694 M mt of cauliflower per year from 0.256 M ha area with an average productivity of about 18.3 mt ha-1 (http://www.ncpahindia.com/cauliflower.php; Senguttuvan et al. 2014). Cauliflower is an excellent source of nutrients having low fat and carbohydrate contents. It is rich in dietary fiber, folate, water and vitamin C and also contains beneficial phytochemicals which reportedly slow down the growth of cancer cells (FAO, 2012). The major pests and diseases of cauliflower are diamondback moth (Plutella xylostella L.), tobacco caterpillar (Spodoptera litura), leaf webber (Crocidolomia binotalis), stem borer (Hellula undalis), aphid, (Brevicornea brassicae), mustard aphid, (Lipaphis erisimi), painted bugs, powdery mildew and downey…show more content…
But a similar study can be performed over a period of 2 years and the data of successive years on pesticide persistence on crops can be generated (Anonymous, 2012). To the best of my knowledge no information is available on the residue persistence of fluopicolide and propamocarb on cauliflower under semi arid climatic conditions. The present study was conducted to evaluate the residue persistence of fluopicolide and propamocarb on cauliflower and their risk assessment under semi arid climatic conditions of India over a period of two years. The variety of cauliflower crop, cropping season and dosage remained the same both the years. The analytical method used for analysis of propamocarb, fluopicolide and its metabolite, 2,6-dichlorobenzamide in cauliflower and soil was validated as per method validation guidelines (SANCO,
