Lyr (Eds.) pounds uphold the tradition of all previous Symposium Proceedings in this series by bringing you research reports on the increasingly complex discipline of fungicide science. As technology develops and new priorities are set for the Modern Fungicides and control of plant diseases, the research undertaken to provide the tools for disease control expands. In order to Antifungal Compounds VI use these tools efficiently, information must be available on the biological and chemical properties of the disease control agents. The present Proceedings provide a unique insight into current research and are an invaluable source of reference for students and established scientists.

  • Clinical Epidemiology and Treatment Outcome of Hexaconazole Poisoning – a Prospective Six Year Study
    Hexaconazole - Clinical epidemiology and treatment outcome A. Anand & P. Abinash ORIGINAL ARTICLE ORIGINAL ARTICLE Clinical epidemiology and treatment outcome of Hexaconazole poisoning – A prospective six year study ACHARYA ANAND1 and PANDA ABINASH2 1Department of Pharmacology, Konaseema Institute of Medical Sciences & Research Foundation, Amalapuram, Andhra Pradesh, India 2Department of Pharmacology, M.K.C.G. Medical College, Berhampur, Odisha, India. Abstract Background: Hexaconazole is a category 3/4 of poison as per the W.H.O Expert Group on Pesticide Residues. Hexaconazole is used to control infection by fungi in paddy and other crops. Apart from destroying the target species, it can also cause damage to humans. There have been discrete reports of instances of human poisoning due to hexaconazole. Methodology: A patient record-based cross-sectional study was carried out in Konaseema Institute of Medical Science & Research Foundation, Amalapuram, Andhra Pradesh, India during a period from March 2014 to April 2020 on 26 confirmed cases of hexaconazole poisoning. The clinic-demographic data, hematological, and biochemical parameters at the time of admission and at 72 hrs as well as the outcome were recorded and analyzed using descriptive statistics and paired t test. Result: The prevalence of hexaconazole poisoning was 4.79% of all poisoning cases. The major clinical presentation was gastrointestinal symptoms with vomiting being commonest. There was no significant change in the biochemical and hematological parameters. The mean duration of hospitalization was 4.93+1.39 days. The recovery rate was 100% without any major sequel. Conclusion: Poisoning due to hexaconazole is uncommon in comparison to poisoning by other pesticides in the agricultural community.

Introduction a—Chlorocarbonyl compounds are very useful starting materials for indutrial scale production of various agrochemicals, pharmaceuticals, dyestuffs and polymers because of their highly reactive multifunctional character through the symergism of carbonyl group and chlorine atom. Their chemical reactions can basically be classi- fied as shown in Scheme 1.

(b) Nucleophilic substitution of the chlorine atom The chlorine atom can be replaced quite readily by nucleophilic agents be- cause of the strong inductive effect of the carbonyl group. (c) Nucleophilic addition to the carbonyl group Additional positive polarization of the C atom of the carbonyl group takes place with the aid of a-chlorine atom leading to a facile addition of nucleophilic agents (Scheme 2 ).
