Two Japanese quail which were incapable of wing movement and three normal quail were examined by histological and ultrastructural methods. The diseased birds had glycogen deposits in their skeletal muscle, cardiac muscle, smooth muscle, and nerve cells of the brain and spinal cord. According to the distribution of the lesions and the characteristics of the deposited glycogen, the diseased birds had glycogenosis which was analogous to type II found in man. The usefulness of this disease as a model for glycogenosis in man is discussed.

Thin layer chromatography was done on tissue extracts of various organs from clinically affected kittens and unaffected unrelated kittens of a similar age, and on serum from carrier cats, affected kittens, related unaffected kittens and unrelated kittens. Spleen and lymph node cell cultures were prepared from 1 affected kitten and the growth medium and cell cultures were analysed for lipids. A lecithin-like phospholipid was identified in the serum of an affected kitten, a carrier cat and a related unaffected kitten. This substance was produced by the liver of affected kittens and also by macrophage-like cells in spleen cell cultures prepared from the spleen of a kitten with signs of the disease. | University of Pretoria.

Potato titbers infested with Phoma exigua var. foveata were uniformly wounded and sprayed or dipped in fungicide suspensions either immediately or after periods of up to 21 days' storage at 5, 10, 15 or 20 °C. Tubers were then stored at 5 °C and gangrene assessed after 12 wk. Incidence of gangrene on untreated tubers was progressively decreased by increasing the length of storage at 15 or 20° (curing) but was not affected by 3 days' storage at any temperature. Fungicide treatment immediately after wounding gave best control of the disease; treatment after 3 days' delay was less effective and after 14 or 21 days was usually ineffective. Gangrene was decreased by fungicides more on tubers stored for 3 or 7 days at 5 °C than at higher temperatures. Control of gangrene by curing or fungicides diminished when the amount of inoculum on tubers was increased. Increasing the amount of fungicide applied improved control and fungicides were more effective in decreasing gangrene on cut and crush wounds than on cut wounds. At the arbitrary concentrations used in these experiments imazalil gave better disease control than thiabendazole, prochloraz, carbendazim plus quinolin 8‐ol or triadimefon.

Late blight has become of increasing economic importance on tomatoes in California during the last few years. Previously, the disease, caused by the fungus Phytophthora in/estans, occurred mainly in coastal areas of California where environmental conditions favored its development. The disease may attack plants at any time during the growing season and, when it is severe, all plants in a field may be killed in a week or two. Late blight also results in great losses of tomatoes in transit, storage, and market.

Research in agronomic improvements of maize, cowpea, Phaseolus vulgaris, peanut, sorghum, mungbean, pigeon pea, soyabean and chick pea is outlined. The achievements and recommendations in the different territories in the fields of: variety assessment, pest, disease and weed control, storage and drying, new production technologies, fertilizing, seed production and Rhizobium inoculation are summarised

Several chemicals were screened for possible control of soft rot development in cabbage tissues. Alum (15% solution and lime (75% suspension)) were found to be promising. Alum was bactericidal against the soft rot pathogen. While lime was not bactericidal but provides protective barrier against the inroad of the pathogen, thus depriving the pathogen of free moisture required for infection. Results showed that neither alum nor lime application was required during the dry season trial due to low disease incidence. However, both treatments provided effective control of the disease during storage in perforated plastic bag kept at ambient temperature

The authors identified an homolactic disease in two wines analysed in the frame of the control foreseen by the EEC legislation for wines destined to long term storage. The wines examined presented increased total acidity comparatively to table wines of their area of origin. On the other hand, the irregular relationship potassium - total cations, was a doubtless proof that the acidity was in reality much higher and had been partly neutralized in order to hide the alteration. It was found out by paper chromatography that the result of the disease was an excessive increase of the lactic acid. The enzymatic determination showed an amount of 3.5 g/l of L(+) lactic acid. Homofermentative and some heterofermentative bacteria were isolated from the samples. The disease occasioned changes to the amount of the wines volatile compounds (ethyl lactate 300 mg/l and acetoin 18 mg/l), determined by gas chromatography
