Beet curly top resistance in USDA-ARS plant introduction lines, 2014. NWISRL
Strausbaugh, C.A.; Panella, Leonard W..
Curly top caused by Beet curly top virus (BCTV) is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate. In order to identify novel sources of curly top resistance, twenty-four plant introduction (PI) lines were screened in a disease nursery in 2014. The lines were arranged in a randomized complete block design with three replications. A curly top epiphytotic was created by releasing approximately 6 viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 23 Jun. Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a...

Development of modified medium for the enhancement in antifungal activity of P. steckii (MF1 mangrove fungi) against verticillium wilt pathogenic fungi of rose BABT
Sabat,Jyotasanmayee; Gupta,Nibha.
The antifungal activity of Penicillium steckii (MF1) against pathogenic fungi of rose causing verticillium wilt was evaluated under differential nutrient condition. A suitable and modified medium was obtained in which test fungus exhibited enhanced antifungal activity and produced larger inhibition zone against the verticillium fungus. The study carried out to modify the medium components at level of nitrogen, carbon source and their concentration on agar plates. Addition of amino acids, metals and plant growth hormones did not show positive effect but glycerol enhanced the antifungal activity very much.

Sustainable management of insect-borne fungal plant diseases: A case study in Canada Taiwan Agricultural Research Institute
Henry Hung-Chang Huang.
[[abstract]]Verticillium wilt of alfalfa, caused by Verticillium albo-atrum, is used as an example for discussion of insect transmission of fungal plant pathogens and management of insect-borne diseases. The disease is important in Europe, North America and northern Japan and it affects the tame hay production and other alfalfa-related industries, including the dehydrated alfalfa industry, the pedigreed seed and leafcutter bee industries and the livestock industry. Studies in Canada reveal that V albo-atrum can be spread by insect, pests, predators and pollinators, as well as by alfalfa pollen. Some insects such as pea aphid, alfalfa weevil, grasshopper and leafcutter bee are effective vectors for the disease. Breeding for disease resistance is thus far...

Verticillium wilt in commercial sugar beet cultivars in Cassia County, ID, 2006 NWISRL
Strausbaugh, C.A.; Camp, S..
Commercial sugar beet cultivars were evaluated in a commercial sprinkler-irrigated sugar beet field near Heyburn, ID where winter wheat was grown in 2005. The field trial relied on natural infection of Verticillium dahliae. The plots were planted on 28 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 15-20 Jun. Plots were four rows wide (22-in. row spacing) and 34.5 ft long. The experimental design was a randomized complete block design with eight replications per cultivar. The field was cultivated on 8 and 20 Jun. The crop was managed by the grower according to standard cultural practices. The percentage of plants with leaves that had dead vein delimited sectors was recorded for the center two rows on 6 Sep. The center two rows...

Verticillium wilt in transgenic sugar beet cultivars in Cassia County, ID, 2006 NWISRL
Strausbaugh, C.A.; Camp, S..
Transgenic (resistant to glyphosate) sugar beet cultivars were evaluated in a commercial sprinkler-irrigated sugar beet field near Heyburn, ID where winter wheat was grown in 2005. The field trial relied on natural infection of Verticillium dahliae. The plots were planted on 28 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 15-20 Jun. Plots were four rows wide (22-in. row spacing) and 34.5 ft long. The experimental design was a randomized complete block design with eight replications per cultivar. The field was cultivated on 8 and 20 Jun. The crop was managed by the grower according to standard cultural practices except for herbicide applications. Transgenic cultivars were sprayed with broadcast applications of glyphosate at...
