Increased Resilience of Peas Toward Root Rot Pathogens Can Be Predicted by the Nematode Metabolic Footprint

چکیده
Legumes are important drivers of soil fertility, however, their frequent use in rotations fosters long-lived soil-borne pathogens that can seriously compromise legume root health and nitrogen fixation. To overcome this, the current study aims at improving general suppressiveness toward pests diseases by agroecosystem management be predicted nematode-based bioindicators. Two long-term organically managed agroecosystems comparing plow shallow non-inversion tillage were analyzed for free-living nematode communities. Soils out these evaluated further a greenhouse assay ability to suppress pea rot caused Didymella pinodella, Fusarium avenaceum , F. redolens . There was trend higher levels disease severity following inoculations with single pathogens, this effect heterogeneous among experiments systems. This mainly due an already very high resident population D. pinodella presence seed-borne oxysporum determined incidence roots irrespective inoculated pathogens. Additional inoculation example, resulted only 8.5% biomass reduction compared non-inoculated control, both Similar losses recorded tilled soils When across treatments, slightly reduced when plough systems (11% Exp 1 and, 9% 2), however greater (33 19% Exp1 2, respectively). Furthermore, metabolic, enrichment, bacterivore carbon footprints nematodes 88, 81, 97% higher, respectively, plough. The metabolic footprint correlated negatively (rho = ?0.71, p 0.047). Hence, effective controlling rot. predicting should extended various aiming its evaluating effects through researchers potentially farm advisors.

Can Cascades be Predicted?
A famous instance is a picture of a receipt taken by a customer at a hunting and fishing chain store called Cabela. The receipt listed a 2.3%“medical excise tax,” which was supposedly levied as part of the Affordable Care Act. This was seen as evidence that there is a hidden tax that consumers are paying for the ACA. The store later cleared this up as being a “software glitch” on their part. Th...

A total of 51 isolates were found showing different disease reaction with 13.7% hi...

Eight commercial pea fields on Prince Edward Island were sampled in June and July over a 2-year period (1986-87) to determine soil population densities and the incidence of nematodes and fungi associated with root rot of peas. Root lesion nematodes (Pratylenchus spp.) were the dominant endoparasitic nematodes recovered from roots and soil. Low populations of the northern root-knot nematode (Mel...
