in order to study the response of new sugar beet hybrids and cultivars to curly top disease in the field conditions, an experiment was carried out in a randomized complete block design with four replications and sixteen treatments in 2007 in fasa. each plot included a hybrid or cultivar planted in three rows with eight meter length and 50cm between- row spacing. after weeding and first thinning...

Fourteen plant species, including 30 genotypes, were assessed for host suitability to Meloidogyne megadora in a growth room at 20 to 28 degrees C. Host suitability was based on the gall index (GI) and the reproduction factor (Rf):final population density (Pf)/initial population density (Pi). The presence of distinct galling was observed on roots of six plant species, and reproduction occurred o...

Breu Branco virus (BE AR 492347) was isolated from Anopheles (Nyssorhynchus) triannulatus mosquitoes captured in Tucuruí, Pará State, northern Brazil, in 1988. No cross-reactivity by complement-fixation tests was observed between Breu Branco virus and other known arboviruses. Results of electron microscopy and physicochemical tests suggested that Breu Branco virus may be a member of the family ...

ABSTRACT It is necessary to use virus-free garlic seeds reach high bulb yields; however, information needed on the number of generations that these can be grown in field conditions without decreasing yield and quality due degeneration. Degeneration dependent production season locality; thus, objective this work was evaluate degeneration cultivars Semiarid region Northeast Brazil, through three ...

While two independent Chinook populations have been identified within WRIA 8 by the PSTRT, Marshall (2000) indicated that there might be enough difference between the North Lake Washington Chinook (Bear/Cottage Lake creeks) and fish returning to Issaquah Creek to consider them separate from one another. WRIA 8 would then contain three distinct Chinook populations (Cedar River, Bear/Cottage Lake...
