Biological control plays a crucial role in grapevine pathogens disease management. The cell-wall degrading enzymes chitinase, cellulase and β-glucanase have been suggested to be essential for the mycoparasitism activity of Trichoderma species against grapevine fungal pathogens. In order to develop a useful strain as a single source of these vital enzymes, it was intended to incorporate the char...

ABSTRACT Seed treatment with Trichoderma harzianum strain T22, which results in colonization of plant roots but little or no colonization of shoots or leaves, had substantial effects on growth of and disease expression in maize inbred line Mo17. Shoots and roots of 10-day-old seedlings grown in a sandy loam field soil were larger (roots were nearly twice as long) in the presence of T22 than in ...

Strains of Enterobacter cloacae show promise as biocontrol agents for Pythium ultimum-induced damping-off on cucumber and other crops. E. cloacae A145 is a mini-Tn5 Km transposon mutant of strain 501R3 that was significantly reduced in suppression of damping-off on cucumber caused by P. ultimum. Strain A145 was deficient in colonization of cucumber, sunflower, and wheat seeds and significantly ...

Abstract The blueberry industry is one of the successful and expanding agricultural cropping systems in South Africa. As a result this growth, research into identifying plant disease agents has become increasingly important, yet there are relatively few scientific reports published on subject country. aim study was to identify causal stunting leaf scorch plants evaluate their pathogenicity. Roo...

identification and transfer of desirable genes from wild relatives to crop species is one of the breeding solutions for producing resistance to pathogens and pests. this study was conducted to evaluate crossability and the response to pythium ultimum in three species of the genus carthamus. to assess response to the pathogen, eight safflower (carthamus tinctorius l) genotypes, two ecotypes of c...

<p>Upaya kriminalisasi yang dilakukan melalui proses legislasi, tidak hanya sekedar membatasi perilaku tetapi juga memberi ancaman hukuman bagi pelanggarnya. Mengingat urgensi adalah pembatasan hak, maka legislatif dalam merumuskan suatu perbuatan sebagai tindak pidana harus mengacu pada prinsip-prinsip hak asasi manusia. Penelitian ini bertujuan menganalisis diskursus teoretik tentang be...
