Five fungicides: Rubigan (EL-222) 12.5 EC, Afugan 30 EC, That-gro 52 F, Antigro 2.1 WP and Bayleton 25 WP were applied for the rost powdery mildew control. Five categories of symptom evaluation from 0-4 were considered to evaluate the effectiveness of each fungicide. Zero represented non diseased where as 1-4 was light to heaviest disease symptom. The efficacy of the five fungicides was evaluated by the mean percentage of disease control (MPDC). The MPDC for Rubigan is 66.27, 38.28 for Afugan, 7.43 for That-gro, 35.23 for Antigro and 18.27 for Bayleton.

The efficacy of inoculating soybean cvs. TGm294-4 and TGm80 in an acid soil (pH 4.6, water) was studied in a field trial in Nigeria. Rhizobium japonicum strains CB1809str('r) and 46spc('t) which had been selected for symbiotic competence in the acid soil were used as inocula. Other treatments included no inoculation, combined nitrogen (150kg N/ha) and lime (1 t/ha). Plants grown in acid soil without inoculation and lime had very few nodules, were nitrogen deficient and grain yields were poor (0.3-0.4 t/ha). Yield responses to combined nitrogen were generally small due to fertilizer loss through leaching. Inoculation greatly increased nodulation, shoot dry matter and shoot N per cent; grain yields were between 1.6 and 2.0 t/ha. Lime improved all harvest measurements in the uninoculated and nitrogen treatments but not in the inoculated treatments. In a duplicate trial without lime on near-neutral soil, similar inoculation responses were obtained at 6 weeks. However, at final harvest there were no significant differences in grain yield between treatments due to late, effective nodulation by unidentified strains in the uninoculated treatments. Assays for strain identity confirmed the successful establishment of the inocula in both soils, with 100 per cent of nodules from inoculated plants containing an introduced strain

The Authors using comparable methods, estimated the effects of including fats in the rations of broilers, and have determined by regression the influence of fatty acid composition on the feed efficiency. | ITALIANO: Gli Autori, reperite in letteratura sperimentazioni metodologicamente confrontabili riguardanti l'impiego della grassutura nell'alimentazione del broiler, hanno quantificato, attraverso l'analisi della regressione, l'effetto della composizione acidica dei grassi ed olii impiegati sull'indice di conversione alimentare.

Analysis of dietary treatment of 750 obese clinic patients was done to determine what factors seem to influence the patient's ability to lose weight and not regain it. Dietary prescription alone is usually inadequate; the environmental, psychological, and motivational factors are very important. Patients must be made more aware of the health hazards of obesity and commit themselves to a change of lifestyle and attitude. Of the patients referred to the clinic, 25% did not return after the initial contact; younger women defaulted more than older women. Women were more successful than men. Default was related to type of referral and occupation, but not to initial body weight. Only 20% of the continuing patients were able to lose 9 kg or more.
