Aflatoxin contamination in mustard (Brassica juncea) in relation to agronomic practices

Abstract

Ajlatoxin contamination in two varieties of mustard (Brassica juncea L), Varuna and BR-40, sown on three planting dates (1, 15 and 30 November) under two different cropping patterns, uiz monocropping and mixed cropping (along with the UP-262 variety of wheat), was examined in rabi (winter) crops of 1987-1988 and 1988-1989. Analysis of variance showed a significant effect of planting date and cropping pattern as well as a combined effect of planting date x cropping pattern. Delayed planting (30 November) resulted in a very high level of ajlatoxin contamination. The level of afatoxin was low when mustard was cultivated along with wheat (mixed cropping). Varuna was more susceptible to ajlatoxin than BR-40. The maximum number of fungi was recorded in mixed cropping samples.

Influence of the cropping pattern on aflatoxin contamination in preharvest Kharif (monsoon) maize crop (Zea mays)

“…However, the greater susceptibility of M, to A j u i w facilitated more aflatoxin production when inoculated. The role of genetic variability in AJuzus infection and aflatoxin production has been determined for several crops including maize (Lillehoj and Zuber 198 I), mustard (Bilgrami et a/ 1991) and groundnut (Mehan and McDonald 1983). Furthermore, the shorter maturity period of the variety Diara composite (80 days) may minimise aflatoxin contamination by reducing the time span of exposure to fungal propagules under field conditions.…”

Detecting and controlling mycotoxin contamination of herbs and spices

“…Bilgrami et al, (1991) found mustard seeds of preharvested crops to be contaminated with various levels of aflatoxin. Delayed planting resulted in a high incidence of aflatoxin.…”

“…Mustard is a susceptible substrate for aflatoxin contamination (Sahay and Prasad, 1990;Bilgrami et al, 1991). Bilgrami et al, (1991) found mustard seeds of preharvested crops to be contaminated with various levels of aflatoxin.…”

Present status, prevalence and seasonal variations of aflaxtoxin in cattle feed, Bihar, India

“…are contaminated by moulds and mycotoxins (6)(7)(8) . Aflatoxin synthesized by Aspergillus flavus, A. parasiticus and A. nominus (9) is most potent human carcinogen, classified as Class I carcinogen (IARC 2002). It is also mutagenic, teratogenic and immunosuppressive.…”
