Bacterial wilt (BW), caused by Pseudomonas solanacearum E.F. Smith, is one of the most destructive disease of tomato (Lycopersicon esculentum Mill.) in the tropics. Twenty tomato lines/accessions previously identified as BW-resistant were evaluated for BW reaction in fields providing high disease pressure at Subang, Indonesia; Los Baños, Philippines; Malaysian Agricultural Research and Development Institute (MARDI), Kuala Lumpur; Asian Vegetable Research and Development Center (AVRDC), Taiwan; and Taiwan Seed Improvement and Propagation Service (TSIPS). Entries also were tested in the greenhouse at the AVRDC with a P. solanacearum strain from Taiwan (Pss4) using a drench inoculation method. Objectives of the study were to identify stable sources of BW resistance for southeast Asian tomato breeding programs, and to determine the correlation between field and greenhouse reactions. Mean entry survival was 21.6% at Subang, 31.9% at Los Baños, 76.7% at the AVRDC, 93.6% at Malaysia, and 93.3% at TSIPS, indicating that most entries were resistant at MARDI and the Taiwan locations but susceptible at Subang and Los Baños. L285 (mean survival = 83.8%) and CRA 84-58-1 (mean survival = 79.4%) were the most resistant entries in the field trials. Mean survival (70.1%) of CRA 66-derived entries was significantly better than the mean of entries with resistance derived from UPCA 1169 or UPCA 1169 plus `Venus' or `Saturn'. Mean survival of AVRDC entries bred in the 1980s (59.4%) was significantly greater than mean survival of AVRDC lines bred in the 1970s (45.7%). The correlation between entry BW percent survival averaged over the five field trials and entry means from drench inoculation in the greenhouse was highly significant (r = 0.70), suggesting that the drench inoculation method is effective in selection for BW resistance.

Teaching about Africa south of the Sahara in American secondary schools is often severely limited or ignored altogether because most teachers believe there is an inadequate number of instructional materials available for use in the classroom. Fortunately, this belief is erroneous. Project Africa, a U.S.O.E. -funded social studies curriculum development center at The Ohio State University, has recently completed an examination of commercially prepared materials currently available for instructional use at the secondary level. In so doing, the Project has located and identified a number of up-to-date, well-structured and generally accurate materials which have the potential for easy adaptation to virtually any type of study about this region as well as to any teaching style.

A study on nutrient uptake (N, P, K, Ca and Mg) by peppers (var. Cubanelle) and fertilizer solute movement in relation to dripper location was conducted in the semiarid southern coast of Puerto Rico at the Fortuna Agricultural Research and Development Center. Soil samples were taken 9, 64, and 118 days after transplanting from each location, with three 15-cm depth increments and three 15-cm horizontal increments away from the dripper. These samples were analyzed for pH, EC, P, K, Ca, and Mg. All fertilizer was applied via drip irrigation. Factorial analysis indicated that solute movements at different positions were not statistically different. The relationships between nutrient uptake versus days after transplanting were of Mitscherlich's curve type. Greatest amount of nutrient uptake occurred during the last third part of the growing season, and followed an order of K > N > Ca > P > Mg.

Abstract The study was conducted on a research lawn at the Ohio Agricultural Research and Development Center, Wooster, Ohio. Insecticides were applied 21 Aug to plots 10 X 10 ft arranged in a RCB replicated four times. Liquid treatments were applied with a CO2 sprayer and Teejet™ 8010VS nozzles at 35 psi pressure that delivered a volume of 3 gal/1000 ft2. The granular treatments were applied with a shaker jar. After all treatments were applied, the area was irrigated with approximately ‘A inch of water bul received no further supplemental irrigation. Environmental conditions at the time of treatment were as follows: NMC—approximately 17/ft2, 100% second instars; turf—level, dry, 2½ inches ht, 60% Kentucky bluegrass and 30% annual bluegrass, 10% weed species, no thatch; soil—moist, 79°F at 1 inch and 77°F at 3 inches deep; weather—mostly sunny, 80°F, 0-5 mph wind. Evaluation on 1 Oct involved counting the number of live NMC and JB larvae in each of six 7X7 inch areas per plot. Analysis of variance was done on plot totals and means were separated by LSD test at P = 0.05.
