Wastage in pears inoculated with Penicillium expansum and Botyfis cinerea was significantly reduced when the fruit was dipped in aqueous formulations of 2-(4'-thiazolyl)-benzimidazole (thiabendazole or 1-(butyl-carbamoy1)-2-benzimidazole carbamic acid methyl ester (benomyl). These compounds also significantly reduced wastage in cherries and apricots inoculated with Sclerotinia fructicola. 5-n-butyl- 2-benzimidazole carbamic acid methyl ester (Parbendazole (R)) reduced rotting by Penicillium expansum in pears but was not tested against the other organisms. Although these three compounds have the benzimidazole ring in common benomyl was the most effective fungicide.

Different Parts

From 81 carnation samples collected in 1967—68 from nurseries in different parts of the country were identified 17 species of fungus, from a total of 177 fungus isolates. Among these, Fusarium oxysporum was most widespread, 31.1 %. F. arthrosporioides, F. avenaceum, F. culmorum, Alternaria tenuis and Cladosporium sp. occurred in considerable quantities. The percentage of Phialophora cinerescens was 1.1 %. In the inoculation trials F. oxysporum behaved as a strongly pathogenic, infecting plants via the air through cut surfaces and via the soil by root-penetration. A. tenuis, F. avenaceum and F. culmorum infected carnations only from the air through cut surfaces. In the fungicide trials against F. oxysporum, spraying the plants infected via the soil proved ineffective. The trials were made with the systemic Benlate (1-(butylcarbamoyl)-2-benzimidazole carbamic acid, methyl ester 50 %), Plantvax (2,3-Dihydro-5-carboxanilido- 6-methyl-1,4-oxathiin-4,4-dioxide), Vitavax (2,3-Dihydro-5-caboxanilido-6-methyl-1,4-oxathiin), and with the non-systemic Dithane M-45 (mancozeb 80 %), Orthocide 50 (captan 50 %) and Pomarsol Forte (thiram 80 %). The dipping of rooted cuttings into Benlate and Dithane M-45 compounds to a certain extent delayed the process of wilting.

Mebendazole is a well known anti-helimintic and belongs to the benzimidazole group of medicines. In order to achieve better medicinal results, i.e. enhanced activity and low toxicity, structural modifications are made in the existing drugs. Some 5-benzoyl-N-[1-(alkoxyphthalimido) benzimidazol-2-yl] carbamic acid methyl ester(3a-c)and 5-benzoyl-N-[1-(2,3-bis oxyphthalimido∕oxysuccinimido propyl benzimidazol-2-yl) carbamic acid methyl ester(7a-b)have been synthesized from two different routes. Structures of the compounds have been established on the basis of elemental analysis and spectral studies. All the synthesized compounds(3a-c)and(7a-b)were assayedin vitrofor antimicrobial activity against mebendazole (itself) and standard [ciprofloxacin (antibacterial) and fluconazole (antifungal)].
