Potatoes are one of the most responsive crops for grooming techniques since in period from seedlings before closing rows easily suppressed by weeds that take away nutrients, water, light it. The factor causes high harm to potatoes is weed. By absorbing a large number nutrients and moisture soil, inhibit growth development plants, reducing their potential productivity. purpose study was establis...

Feet and legs issues are some of the main causes for sow removal in the US swine industry. More timely lameness detection among breeding herd females will allow better treatment decisions and outcomes. Producers will be able to treat lame females before the problem becomes too severe and cull females while they still have salvage value. The objective of this study was to compare the predictive ...

To better dissect non-host resistance against haustorium-forming powdery mildew pathogens, a sow thistle powdery mildew isolate designated Golovinomyces cichoracearum UMSG1 that has largely overcome penetration resistance but is invariably stopped by post-invasion non-host resistance of Arabidopsis thaliana was identified. The post-invasion non-host resistance is mainly manifested as the format...

Different formae speciales of Fusarium oxysporum are the main causal agent of Fusarium wilts. In 2008 and 2009 we collected F. oxysporum samples from symptomless Abutilon theophrasti, xanthium strumarium, Chenopodium album, Matricaria perforata, Ambrosia artemisiifolia, Polygonum lapathifolium, Sonchus arvensis, Amaranthus blitoides, Amaranthus retroflexus, Datura stramonium, Sorghum halepense ...

As an initial step to mapping quantitative trait loci for species differences and adaptive radiation of insular endemics in Macaronesia, a genetic linkage map was constructed from an intergeneric backcross between Lactucosonchus webbii and Sonchus radicatus, core members of the tree lettuces in the Macaronesian Islands. A total of 152 amplified fragment length polymorphism markers were mapped i...

The objective of this study was to validate the use of exogenous gonadotropin (PG600) treatment for stimulating estrus in noncyclic gilts and to compare lifetime productivity of gilts recorded as having natural (NAT) versus PG600-induced (PG600) first estrus in a commercial setting. Prepubertal Camborough gilts (n = 4,489) were delivered to a gilt development unit (GDU) with the goal of deliver...
