Myxobacteria exert partial control of damping-off and root disease in container-grown tree seedlings.

Effect of certain fungicides in controlling damping-off in seedlings of ponderosa pine, Douglas-fir, and Colorado blue spruce

Damping-off of Sweetgnm by Pythium sylvaticum

During the spring of 1964, preand postemergence damping-off killed many sweetgum (Liquidambar styraciftua L.) seedlings in a nursery at Stoneville, Miss. Fusarium solani (Mart.) Appel & Wr., Sclerotium rolfsii Sacc., Talaromyces spiculisporum Benjamin, and Pythium sylvaticum Campbell & F.F.Hendrix were isolated from the diseased seedlings. At soil temperatures similar to those prevailing when d...

The Effect of Trifluralin on Rhizoctonia solani (isolate AG4), Causal Agent of Soybean Damping off

Damping off caused by Rhizoctonia solani (isolate AG4) constrains growing soybean in the north Iranian province of Golestan. The pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. The response of soybean cv. Williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. On mal...

Comparative Research on Optimal Damping Matching of Seat System for an off-Highway Dump Truck

To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...
