Ground pork meat was cured with the addition of 0, 50, 100, 156, and 200 mg/kg NaNO2, pasteurized and irradiated with 0, 3, 6, 9, 10, 20, 30, 40, and 50 kGy. After irradiation the samples were inoculated with a mixture of Clostridium botulinum type A, B and E spores, incubated at 30 degrees C for 28 days and tested for the presence of botulinal toxin. Doses up to 9 kGy caused a decrease of NaNO2 content with a corresponding decrease in antibotulinal activity. High irradiation doses resulted in a dose-dependent decrease in nitrite content with complete loss of antibotulinal activity.

The efficacy of dipikarsulben herbicide 2(4,6) di methoxy pyrimidin-2yl-amino-carbonyl-benzoic acid methyl ester, with g and 10 WP londax formulation. The efficacy was tested on a direct seeded rice field at Singamerta Experimental Farm, during the 1984/1985 wet season. Nine treatments were tested in a randomized complete block design with three replications. The results showed three rates of dipikarsulben, 15, 30 and 45 g/hs respectively, which were applied at 5 days after sowing causing no toxicity on the rice plants. The herbicide was also found to be effective in controlling Monochoria vaginalis and Marsilea crenata. Plots treated with herbicide produced higher yields than that of the check plot.

— ‐The efficacy of cythioate (O,O‐dimethyl‐O‐p‐sulphamoylphenyl phosphorothioate) against Ctenocephalides spp was investigated in two controlled field trials involving 12 dogs and 11 cats, respectively. At a dose‐rate of 3 mg kg‐¹, the flea population of greyhounds heavily infected with Ct. canis and Ct.felis was reduced by over 95 per cent, while an efficacy figure in excess of 90 per cent was recorded against Ct. felis in lightly infected cats treated at 1.5 mg kg‐¹. Résumé— L'efficacité du cythioate (O,O‐dimethyl‐O‐p‐sulphamoyl‐phenyl phosphorothioate) contre Ctenocephalides spp a étéévaluée dans deux expérimentations controlées par rapport à des lots témoins et portant respectivement sur 12 chiens et 11 chats. Pour une dose moyenne de 3 mg Kg‐¹, la population des puces sur des Greyhounds lourdement infestés par Ct. canis et Ct.felis fut réduite de plus de 95%, cependant qu'un taux d'efficacité supérieur à 90% fut constaté contre Ct. felis sur des chats légèrement infestés, à la dose de 1.5 mg Kg‐¹. Zusammenfassung— Die Wirksamkeit von Zythioath (O,O‐dimethyl‐O‐p‐sulphamoylphenyl phosphorothioate) gegen Ctenocephalides spp. wurde in zwei kontrollierten Feldversuchen an 12 Hunden und 11 Katzen geprüft. Bei einer Dosis von 3 mg/kg wurde die Flohpopulation von Greyhounds, die mit Ct. canis und Ct. felis massiv infiziert waren, über 95% reduziert. Bei leicht infizierten Katzen, die mit 1.5 mg/kg behandelt wurden, lag die Wirksamkeit gegen Ct. felis bei über 90%.

There are many kinds of nutrients contained in leaves of common seabuckthorn and some of them even more than in its juice and fruit. The authors have succeeded in processing several kinds of tea from common seabuckthorn into green, red and three types of jasmine tea. The analysis shows that the biochemical indices equal to those of some famous Chinese tea; the colour of the tea liquor is good also with abundance of nutrients. The common seabuckthorn tea may become a health protection tea with wide prospect in China. The qualities of the common seabuckthorn tea and its processing technology are described in this paper.
