Other claims from this paper (18)
- Observation Wheat yield decline was absent on soils cultivated for less than 10 years.
- Observation Barley and sorghum crops were unaffected by yield decline.
- Intervention effect Zinc application gave a small wheat yield response in one experiment.
- Intervention effect Applications of multiple nutrients did not significantly increase wheat yield.
- Association More Pratylenchus thornei were associated with unfumigated wheat plots than barley plots.
- Intervention effect Aldicarb increased grain yields of all nine tested cereal genotypes.
- Association Yield response to aldicarb correlated with genotype tolerance to P. thornei.
- Observation Pratylenchus thornei occurred to 120 cm depth.
- Intervention effect Aldicarb did not affect deep P. thornei numbers.
- Intervention effect Methyl bromide controlled P. thornei at 30–90 cm depth.
- Intervention effect Aldicarb nearly eliminated surface P. thornei.
- Intervention effect Aldicarb did not affect common root rot or crown rot incidence.
- Intervention effect Methyl bromide controlled two fungal pathogens and P. thornei.
- Intervention effect Methyl bromide produced 9% higher yields than aldicarb.
- Intervention effect Ethylene dibromide had no consistent effect on wheat yield or P. thornei numbers.
- Intervention effect Terbufos slightly reduced P. thornei numbers.
- Intervention effect Terbufos slightly increased wheat yield.
- Mechanism The authors concluded that P. thornei partly causes regional wheat yield decline.
