“…Selective induction of symptoms was achieved in California in vines infested with Col. vitis in a glasshouse (Smith and Stafford 1948). Selective elimination was achieved in the field in California and South Africa by sprays timed to the narrow window when Col. vitis is exposed, immediately after bud burst (Smith and Schuster 1963;Dennill 1986).…”

“…In Shiraz and Cabernet Sauvignon at the same site, unburst buds and shoots in their vicinity were similarly damaged. We attribute this associated shoot injury to Col. vitis following other authors (Smith and Stafford 1948;Kido and Stafford 1955;Smith and Schuster 1963;Jeppson et al 1975;Dennill 1986Dennill , 1991. Shoot injury is due to a lower Col. vitis infestation per developing bud the previous season, than infestations causing bud-axis necrosis and burst failure.…”

“…However, eriophyoid mites are a possible cause, already supported by extensive research. Bud burst failure and high yield loss due to Col. vitis were reported from California (Smith and Stafford 1948) and South Africa (Dennill 1991). In Australia 'a shoot restriction disease' was successfully treated with lime sulphur (CSIRO 1950, p. 34;CSIRO 1951), and extensive bud surveys linked Col. vitis (Eriophyes vitis) to bud burst failure (May and Webster 1958).…”

“…Colomerus vitis was until recently considered to comprise morphologically identical, but biologically distinct strains; the bud-dwelling bud mite, the leaf gall-inducing erineum mite, and a localised leaf curl strain (Smith and Stafford 1948;Jeppson et al 1975;Duso and De Lillo 1996). Recent research separated bud and erineum strains into distinct species (Carew et al 2004); the economically unimportant erineum strain, and the leaf curl strain not reported in Australia (Duso and De Lillo 1996), are thus not considered here.…”

Eriophyoid mite damage in Vitis vinifera (grapevine) in Australia: Calepitrimerus vitis and Colomerus vitis (Acari: Eriophyidae) as the common cause of the widespread ‘Restricted Spring Growth’ syndrome

Leaf and shoot distortions and retarded shoot growth in Vitis vinifera L. prevalent in Australian vineyards in early spring, were investigated in replicated field experiments over 3 yrs. Leaf distortion and retarded shoot growth were identified as damage due to feeding of extremely high populations of over-wintered deutogynes of Calepitrimerus vitis (Nalepa) (grape rust mite). This damage was hitherto known in Australia as 'Restricted Spring Growth' (RSG), a syndrome comprising several growth abnormality symptoms, none with a clearly identified cause or a successful treatment. A successful treatment against C. vitis was used to selectively eliminate RSG, while C. vitis numbers were recorded using a validated trapping technique; intercepting deutogynes migrating from winter shelters in the wooden vine structure, to emerging green tissues. Severe leaf distortion was associated with > 400 C. vitis deutogynes per spur, while > 1000 per spur had the added effect of severely retarding shoot growth. A 43.0-47.2% shoot length reduction was recorded for Cabernet Sauvignon, 27.1-32.8% for Sauvignon Blanc, when 4-6 leaves were separated. Symptoms were most prominent up to 8-9 separated leaves, however 24.7-30.4% shoot length reduction was still evident at flowering, and 12.8% circa fruit set. C. vitis effect on vine fruitfulness, and yield parameters at fruit set, were also studied. Once successfully treated to prevent C. vitis damage, poor bud burst remained evident in some vineyards. Surveys of unburst buds from such vineyards revealed presence of Colomerus vitis (Pagenstecher) (grape bud mite). When Col. vitis numbers in unburst buds reached 100-500 per bud, apical meristems of primary, and commonly also secondary buds were dead, preventing bud burst. The remaining living scale tissue was distinctly scarred. Bud and associated shoot damage were documented. Retarded shoot growth and leaf distortion, previously attributed to RSG, are misdiagnosed C. vitis spring feeding damage. Clustered high infestations of Col. vitis can cause bud-axis necrosis, bud burst failure, shoots with short basal internodes, and short, thin, zigzagged shoots with absent fruit clusters; all previously considered RSG.

“…Large populations of C. vitis in Australia and Europe were associated with spring leaf and shoot distortions and retarded growth in emerging green tissue as well as late summer leaf bronzing and crop losses (Hluchy and Pospisil, 1992;Perez-Moreno and Moraza-Zorilla, 1998;Duffner, 1999;Bernard et al, 2005). Bud burst failure and high yield losses were correlated with C. vitis infestations in California (Smith and Stafford, 1948), South Africa (Dennill, 1986) and Australia (May and Webster, 1958;Frost, 1996;Whiting and Strawhorn, 1997). These symptoms are similar to SSS experienced in vineyards in the Pacific Northwest.…”

-Short Shoot Syndrome (SSS) causes severe crop losses in Oregon vineyards due to bunch necrosis during the early part of the season. Other symptoms include malformed leaves, unusually short and angled shoots, scar tissue and bronzed leaves close to harvest time. This work shows that SSS found in Oregon vineyards is closely associated with grape leaf rust mite, Calepitrimerus vitis (Nalepa) infestations. Very few bud mites, Colomerus vitis (Pagenstecher), were found in the vineyards during the current year and no relationship could be found between SSS symptoms and this species. During winter, rust mites are dormant and no evidence of direct bud damage from rust mites was found inside undeveloped buds. Tissue damage from mites was first observed between bud break and the two-leaf stage in mite infested vineyards. Rust mite colonies were found under outer bud scales and bark of canes close to the buds. Crop losses as high as 23.7% were directly linked to rust mite infestations and SSS from several vineyards sampled in Oregon.
