Summary The effects of chloropicrin fumigation of field soils before replanting apple are frequently predicted from bio-assays using pot-grown apple seedlings. The results of 506 such bio-assays carried out during 12 years are discussed with referenc

SUMMARY Phytophthora species were isolated from infested orchard soils using apple fruit as bait at intervals during the periods July 1956 to August 1957, January 1957 to June 1958, and January 1969 to June 1970. When baited soils were kept out of do

SUMMARY The effects of fumigating field soils before replanting apple are frequently predicted from bioassays where apple seedlings are grown in pots, some containing untreated soil and the others containing chloropicrin-fumigated soil. The results f

During routine, annual, field wilt-resistance trials of hop progeny, ‘breakdowns’ of resistance occurred in control varieties. Pot-plant pathogenicity tests of isolates from these trials, and other isolates obtained during farm surveys, confirmed

SUMMARY Large differences were found between populations of Thielaviopsis basicola in soils from nursery layer-beds of different cherry rootsock clones. The soils were classified primarily into those with small (< 700 propagules/g) and those with lar

SUMMARY Several lines of circumstantial evidence collectively indicated that poor early growth of apple (‘replant disease’) might be associated with the effects of soil-borne pythiaceous fungi. This hypothesis was supported by pathogenicity tests

SUMMARY One-to three-year-old trees of the apple variety Cox's Orange Pippin were highly resistant to infection by Phytophthora cactorum except during the spring from March to May. A rapid increase in resistance occurred after this time from the comm
