Verticillium wilt (caused by V. dahliae ) is an important soilborne disease that limits watermelon ( C. lanatus ) production in Washington State and worldwide ( du Toit et al., 2005 ; Dung and Weiland, 2014 ; Johnson, 2012 ; Paplomatas et al
Verticillium dahliae infects over 300 cultivated plants, including strawberry. The fungus destroys vascular tissues causing drought stress resembling foliar symptoms. The outer leaves wilt and turn brown and the inner wilt but remain bluish green
soilborne pathogens affect the production of spinach leaf and seed crops ( Correll et al., 1994 ). Although Verticillium dahliae causes Verticillium wilt of more than 200 species of vegetables, field crops, and trees, the fungus was not, until recently
Verticillium wilt caused by the soilborne fungus V. dahliae is a significant disease affecting watermelon ( Citrullus lanatus ) production in Washington State ( Dung and Weiland, 2014 ; Sunseri and Johnson, 2001 ). Once established in the field
estimated at 243 ha (Timothy Waters, personal communication). One of the barriers to increasing watermelon production in this region of southeastern Washington is verticillium wilt (caused by Verticillium dahliae ), which can cause rapid vine decline and
available ( Lebeda et al., 2009 ). To achieve this, continual screening for new/additional resistances is necessary because new diseases emerge or change. Verticillium wilt caused by Verticillium dahliae Kleb. is a serious disease of lettuce that was first
We are using Mentha longifolia (Lamiaceae) as a diploid model species with relevance to the polyploid commercial mints ( Mentha L. spp.) and to the study of plant resistance to vascular wilt diseases. Verticillium wilt, incited by the fungus
Abstract
‘Quinte’ (ST-19) is a midseason, large, firm, crimson-colored tomato (Lycopersicum esculentum Mill.). It was developed in the early 1970s to replace ‘Moira’. Named after the Bay of Qunite, it is now extensively grown in eastern Ontario, Canada, and the northeastern United States, especially in areas where Verticillium wilt (Verticillium alboatrum Reinke & Berth, and V. dahliae Kleb.) is a problem. The fruit is suitable to the fresh-market and processed-juice industries.
. Furrow irrigation can be thought of as periodic flooding of fields. Major constraints to chile pepper production in New Mexico are soilborne diseases, which are manifested by wilt symptoms after plant infection. Verticillium dahliae is a major
Cercis canadensis, Eastern Redbud, is very Cercis canadensis, Eastern Redbud, is very susceptible to infection by Verticillium Wilt caused bysusceotible to infection by Verticillium Wilt caused by the common soil-borne fungi Verticillium albo-atrum and Verticillium dahliae. Little is known about the inoculum levels, the time required for natural infection to occur and how fast the pathogen travels inside the host species. One-year-old Cercis canadensis seedlings were planted in 7.6 liter (2-gallon) containers with a 1:1:2 soil/sand/perlite mix inoculated with five levels (0, 10, 100, 500, and 1000 microsclerotia/g soil) of V. dahliae prior to planting. At the end of the first growing season, half of the plants were removed from the containers, surface sterilized, dissected and root sections plated out on a Verticillium selective media. The remaining plants were grown for a second season. Infection first occurred in plants which received 100, 500 or 1000 ms/g at the end of the first season. The infection had spread at least 5 cm during the first growing season.
