CORESTA Congress, Kyoto, 2004, A 04 A review on flue-cured tobacco cultivar development in South Africa - Lowveld Tobacco Growers Association SCHOLTZ A. Lowveld Tobacco Growers Association, Nelspruit, South Africa Flue-cured tobacco is grown in South Africa in four diverse areas ranging from fast growing high rainfall areas to a very slow ripening area with high heat intensity and low rainfall. All flue-cured tobacco is grown under irrigation. The main disease...
CORESTA Congress, Kyoto, 2004, APSSPT 02 The implementation of integrated pest management on flue-cured tobacco cultivation in South Africa LUTTIG M.; GELDENHUIJS D.M.; VAN JAARSVELD E.; SCHOLTZ A. Lowveld Tobacco Growers Association, Nelspruit, South Africa The Lowveld Tobacco Growers Association (LTGA) has developed an Integrated Pest Management (IPM) program as an alternative approach to chemical crop protection. The IPM program includes seedbed implementation as well as field applications. During...
CORESTA Meeting, Agronomy/Phytopathology, Cape Town, 2001, A 03 The influence of soil compaction and calcium on the uptake of phosphate for flue-cured tobacco DREYER J.G.; CLAASSENS A.S.; SCHOLTZ A. Lowveld Tobacco Growers Association, Nelspruit, South Africa The following problem have lead to this research project: The high application rate of phosphate by the tobacco farmer in the Lowveld and the low phosphorus content that where obtained in the leaves. Phosphates in the leaf correlate with leaf...
CORESTA Meeting, Agronomy/Phytopathology, Cape Town, 2001, AP 20 Evaluation of tobacco cultivars and metalaxyl to reduce the impact of Phytophthora nicotianae in South Africa VAN JAARSVELD E.; WINGFIELD M.J.; DRENTH A. Lowveld Tobacco Growers Association, Nelspruit, South Africa Phytophthora nicotianae is an important root and stem pathogen of tobacco (Nicotianae tabacum L.) in South Africa. Growers strive to control the resulting disease, known as black shank, with metalaxyl treatments and by planting resistant cultivars....
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 82, AP9 Production of tobacco seedlings in pine-bark medium on permanent seedbed structures – the use of steam sterilization as opposed to methyl bromide SCHOLTZ A.; SONNENBERG S.M.; SMITH P.J. Lowveld Tobacco Growers Association, Nelspruit, South Africa The production of tobacco seedlings on permanent seedbed systems in composted pine-bark medium was developed over the past 6 years and are currently implemented by a vast number of commercial growers. The concept consists of a permanent constructed...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 117, P02 Evaluating different metalaxyl formulations for control of black shank (Phytophthora nicotianae ) on flue-cured tobacco in South Africa and evaluating cultivars for resistance against black shank in combination with Ridomil G (metalaxyl) VAN JAARSVELD E.; SCHOLTZ A. Lowveld Tobacco Growers Association, Nelspruit, South Africa Black shank, caused by the fungus Phytophthora nicotianae is a highly destructive and wide spread tobacco disease in the Lowveld (South Africa). The aim of this study was: (1) to evaluate different metalaxyl formulations for controlling Black shank...
Bull. Spec. CORESTA Symposium, Taormina, 1986, p. 72, P15, ISSN.0525-6240 Control of bacterial wilt (Pseudomonas Solanacearum) : chlorination of irrigation water LOUW A. Lowveld Tobacco Growers Association, Nelspruit, South Africa P. solanacearum has an outstanding ability to survive in water. Run of water from infested fields are a constant source for infesting open irrigation sources. The threat of contaminating seedbeds by irrigation water is minimized if the water is...
Tob. Sci., 1981, 25-14, p. 48-51, ISSN. 0082-4523 Developing formulas for estimating burley tobacco barn construction costs BRADFORD G.L.; HALLARON J.L.; SHUFFETT D.M.; DUNCAN G.A. Kentucky Agricultural Experiment Station, Lexington, Kentucky USA Multiple regression models were used to develop alternative formulas for estimating burley tobacco barn construction costs. Barn cost was related to size (square metres and height), type of builder, year constructed and location. Cross-section,...
Tob. Sci., 1973, 17-33, p. 96-98, ISSN.0082-4523 Influence of herbicides on burley tobacco leaf chemistry LONG J.W.; DAVIS D.L.; THOMPSON L., Jr Kentucky Agricultural Experiment Station, Kentucky USA Three herbicides-benefin, diphenamid, and pebulate-at use and double use rates did not alter the alkaloids, total nitrogen, total volatile bases or total sterols of mature, air-cured tobacco leaf. However, benefin significantly lowered the nitrate...
