SPRAY NOZZLES PERFORMANCE IN FUNGICIDES APPLICATIONS FOR ASIAN SOYBEAN RUST CONTROL

Evaluation of various spraying equipment for effective application of fungicides to control Asian soybean rust

Fungicides manufactured to control soybean rust are effective; however, successful control of this disease will mostly depend on proper application methods. Spray coverage and deposition from 9 application equipment/spray nozzles were analyzed. In general, the spray treatments with air assistance were more effective in spraying rust fungicides than the treatments with the conventional boom spra...

Fighting Asian Soybean Rust

Phakopsora pachyrhizi is a biotrophic fungus provoking SBR disease. SBR poses a major threat to global soybean production. Though several R genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly overcame this resistance. Therefore, fungicides are the only current means to control SBR. However, insensitivity to fungicides is soaring in P. pachyrhizi and, therefore, ...

Models and Applications for Risk Assessment and Prediction of Asian Soybean Rust Epidemics

Asian rust of soybean [ (L.) Merril] is one of the most important fungal diseases of this crop worldwide. The recent introduction of Syd. & P. Syd in the Americas represents a major threat is extremely aggressive under favorable weather conditions, causing rapid plant defoliation. Epidemiological studies, under both controlled and natural environmental conditions, have been done for several dec...

Identification and analyses of candidate genes for rpp4-mediated resistance to Asian soybean rust in soybean.

Asian soybean rust is a formidable threat to soybean (Glycine max) production in many areas of the world, including the United States. Only five sources of resistance have been identified (Resistance to Phakopsora pachyrhizi1 [Rpp1], Rpp2, Rpp3, Rpp4, and Rpp5). Rpp4 was previously identified in the resistant genotype PI459025B and mapped within 2 centimorgans of Satt288 on soybean chromosome 1...
