Description
Summary:The aim of this study was to study the effect of herbicides on the breakdown of mango fruit to identify the fungi recovered from the herbicides-treated fruit and to determine the potential use of herbicides in a rapid quantitative measure of the pathogenic component of the fruit storability. Quick detection of symptomless latent anthracnose of mango was used as nine herbicides. It may be seen that all the herbicides tested were found induce the manifestation of latency earlier than the control. It is interesting to note that paraquat (3000 ppm) was able to manifest the disease (64.33%) within 3-5 days versus 7-10 days in control followed by Basalin (36.66%) and Alachlor (34.00%). Butacholar and Pretalacholar were not effective even over 6-10 days in inducing the manifestation of latent infection. For fruits treated with paraquat, one can detect the disease much earlier and decide whether they are fit enough for long-term storage, export or quick disposal in the local market.
