1 Bacterial Canker Susceptibility of Peach:Almond Hybrid Rootstocks for California Stonefruit Orchards Roger Duncan University of California Cooperative Extension Modesto, CA Michael McKenry Dept. of Nematology, UC Riverside

2 Bacterial Canker: a devastating disease of Prunus spp. Pseudomonas syringae pv. syringae (Pss) Pathogen may enter through lenticels? Islands of necrotic tissue coalesce into large cankers

3 Gummosis Death of small limbs, scaffolds or entire trees

4 History of Bacterial Canker First work done in Europe about 1850 (Barss, 1913) Serious outbreaks in Oregon as early as First formal description in 1891 by Sorauer First evidence as a bacterium infection in 1902 by Van Hall of University of Amsterdam First gummosis of cherry in US by Griffin in 1911 Gummosis of apricot first reported by Barrett in 1918 in California

5 Conditions Associated with Bacterial Canker Young trees Replanted almond and stonefruit orchards Sandy soil Ring nematode (Mesocriconema xenoplax) Stress

6 The onset of bacterial canker symptoms occurs when external biotic and abiotic factors predispose a tree to the disease.

7 Predisposing factors Ring nematode infestation Plant nutrition (N, Ca) Temperature (freezing/thawing) Soil conditions (texture, moisture, and ph) Cultural practices (fall or dormant pruning, irrigation, rootstock)

8 New Rootstocks for California ~95% of all almonds and peaches in California are grown on Nemaguard or Lovell rootstocks. Emerging interest in new rootstocks. Peach / almond hybrids becoming popular due to high vigor, earlier & larger yields. Peach / almond hybrids include Hansen 536, Bright s Hybrid, Nickels, Alpha, Titan...

9 Q: Will peach / almond hybrid rootstocks perform better than standard rootstocks in bacterial canker sites??

10 Two rootstock trials were initiated in bacterial canker sites Commercial Peach Orchard Commercial Almond Orchard Monitor tree growth, yield, tree nutrition, nematode populations, bacterial canker incidence and severity.

11 Rootstock Trial #1 Established Feb., 1999 Third generation peach orchard Site with a history of severe bacterial canker Soil treated with a solid, tarped methyl bromide 400 lb per acre Drip irrigated Treated with sodium tetrathiocarbonate (Enzone ) annually

12 Trial #1: Peach Rootstock Trial Rootstocks include: Nemaguard (peach) Lovell (peach) Deep Purple (plum) Hansen 536 (peach / almond hybrid) Alpha (peach / almond hybrid) Viking (peach / almond / plum / apricot hybrid) Eight, four-tree replicates

13 Superior Fruit Ranch Rootstock Trial est. February, 1999 Variety = Riegel Sandy soil History of severe bacterial canker

14 Aerial Photo of Riegel Roostock Trial 2002

16 A Comparison of Peach Rootstocks with Bacterial Canker Rating Severity > 1 Reigel Cling Peach Rootstock Trial. April, 2003 (5th leaf) P erce nt of Trees Affected Rating system: 0 = no symptoms 1 = some shoot tip death 2 = up to 1/3 tree affected 3 = 1/3-2/3 tree affected 4 = 100% of tree affected Hansen Alpha Nemaguard Lovell Viking

17 A Comparison of Peach Rootstocks Killed by Bacterial Canker 100 Reigel Cling Peach Rootstock Trial. April, 2003 (5th leaf) Percent of Trees Affected Hansen Alpha Nemaguard Lovell Viking

19 Trial #2: Almond Rootstock Trial Est Lovell (peach) Nemaguard (peach) Guardian (peach) Hansen 536 (peach-almond) Bright s hybrid (peach-almond) Nickels (peach-almond) Viking (peach-almond-plum-apricot) Alpha (peach-almond-plum-apricot)

20 Rootstock Trial #2: Almond Established March, 1998 Nonpareil almond Third generation orchard Area with a history of severe bacterial canker Soil treated with a solid, tarped methyl bromide 400 lb per acre Flood irrigated Ten, 5-tree replications of each rootstock

21 A Comparison of Almond Rootstocks for Incidence of Bacterial Canker April, 2002 (5 th leaf) Percent Trees Affected A B B C C C C C Nema Lovell Guardian Atlas Viking Bright's Nickels Hansen

22 Rootstock Trial Conclusions Peach / Almond hybrid rootstocks should not be planted in sites prone to bacterial canker. Hansen 536 P/A appears to be particularly susceptible to bacterial canker More research is needed to find a bacterial canker resistant rootstock
