But Jude Boucher, a commercial crop educator with the University of Connecticut Cooperative Extension Service, said the new varieties, on balance, were better: more productive and often resistant to things like corn rust, with ears that are larger and taste better than the old corn.
All the compounds were screened for in vivo fungicidal activity against southern corn rust (SCR).
The biotrophic fungus Puccinia sorghi Schwein (Ps) is responsible for maize common rust, an endemic disease of maize (Zea mays L). in Argentina that causes significant yield losses in corn production.
The major lines in this group PANT, BAJIM, CM, and CML possessed the distinct characteristics of orange-colored grains, acidic soil tolerance, and resistance against ear rot, tar spot, stalk rot, leaf blight, rust, southwestern corn borer, and fall armyworm.
Examples of this condition include the downy mildews (Sclerospora species) and rusts (Puccinia species) of corn in Africa during the 1950s, the introduction of the coffee rust fungus into Brazil in the 1960s, and the entrance of the chestnut blight (Endothia parasitica) into the United States shortly after 1900.
Such a mixed QTL effect distribution can be found in maize e.g. for rust [ 13], Giberella ear rot [ 14, 15] or to a lesser extent for Northern corn leaf blight [ 16, 17].
(If you want to do the fudge experiments yourself, a recipe and an explanation of how to vary it is available at nytimes.com/science/.) Dr. Rust said she had also experimented with cornstarch, corn syrup and applesauce.
These endophytic fungi produce antifungal metabolites and were used for biocontrol of rice blast [ 19], wheat leaf rust [ 19], potato late blight [ 20] and corn leaf blight [ 21].
A collection of 6,308 fungal genes was identified and compared to sequences of the cereal rusts, Puccinia graminis f. sp. tritici (Pgt) and stripe rust, P. striiformis f. sp. tritici (Pst), and poplar leaf rust Melampsora species, and the corn smut fungus, Ustilago maydis (Um).
