Disease-Resistant Pear Varieties
Fire blight is the disease that decides whether a pear tree reaches middle age. It is bacterial, it enters through blossoms in warm humid weather, and it runs down the shoots fast enough that the classic symptom — blackened, hooked shoot tips, as if scorched — can appear within days. There is no spray that cures it; the response is cutting well below the visible margin and sterilising between cuts. Which is why resistance in the variety is worth more here than in almost any other fruit.
These 13 varieties carry documented resistance, and the disease column gives each one's rating rather than a blanket claim. Beyond variety choice, three habits do most of the work: avoid heavy nitrogen, which pushes the soft fast growth blight prefers; prune in dry weather, never in a wet spring; and remove any blighted wood the season you see it rather than the following winter. Asian pears are included where the data supports them and are generally the more blight-prone half of the family.

| Variety | Disease resistance | Ripens | Zones | Notes | Where to buy |
|---|---|---|---|---|---|
| Ayers | excellent (very fireblight resistant) | Aug | 6-9 | sweet, juicy, low grit; excellent fresh dessert pear for the SouthA top pick for the Southeast: fireblight-resistant with a moderate chill need. Reported chill varies by source (roughly 400-600 hrs); plant a pollinizer for best set. | Buy $64.99 |
| Baldwin | moderate resistance to fire blight | Late Aug - Sept | 8-9 | dual purpose, good fresh and for canningThe latest of the low-chill Southern pears, which is exactly why it is worth planting alongside Hood and Flordahome - it stretches the harvest a month past them. | Browse growers |
| Chojuro | better fire blight resistance than the smooth-skinned Asian pears | Late Aug | 5-9 | crisp and juicy with a distinct butterscotch flavorA russeted Japanese pear; russet Asian pears run more fire blight resistant than the smooth yellow or green Chinese types. Stores up to five months, which is unusual for an Asian pear. No chill figure is published in the extension source. | Buy $64.99 |
| Flordahome | resistant to fire blight and leaf spot | July - Aug | 8-9 | soft, sweet eating pear — A UF/IFAS release for North and Central Florida home gardens. Pair it with Hood and each improves the other's crop. | Browse growers |
| Harrow Delight | very resistant to fire blight and pear scab | Summer, about two weeks before Bartlett | 4-8 | juicy and sweet, smooth with almost no grit cellsBears young, though it still takes 2 to 3 years to its first fruit, and it tends to crop heaviest every other year. Pick before it ripens on the tree and finish it in storage for 5 to 7 days. No chill figure is published in the extension source, so it is left blank rather than carried over from a nursery catalog. | Buy $64.99 |
| Harrow Sweet | excellent (fireblight and mildew resistant) | Late Sept | 4-8 | smooth, juicy, sweet Bartlett-type; good freshA modern pear from Agriculture Canada's Harrow, Ontario program, combining Bartlett-like eating quality with strong fireblight resistance and good cold-hardiness. Late bloom, so pair with another late bloomer. | Browse growers |
| Hood | moderate resistance to fire blight | Mid-July | 8-9 | soft-fleshed eating pear, not a hard canning typeOne of the two pears bred for the Deep South, and the standard pollination partner for Flordahome. Its very low chill requirement is the whole point - it fruits where a 600-hour pear never breaks dormancy properly. | Browse growers |
| Kieffer | excellent (very fireblight resistant) | Oct | 4-9 | coarse, gritty, best cooked/canned rather than freshA nearly foolproof, self-fertile, fireblight-resistant communis x pyrifolia hybrid with low chill and wide adaptation, best for canning and preserves rather than dessert. | Buy $58.95 |
| Moonglow | excellent (bred for fireblight resistance) | Aug-Sept | 5-8 | soft, mild, mellow, low grit; good freshA USDA fireblight-resistant variety that ripens early; plant a second pear for reliable set. It is also a dependable pollinizer for Bartlett, Bosc, Seckel, and other European pears. | Browse growers |
| Orient | very resistant to fire blight, resistant to leaf spot | Late July - early Aug | 8-9 | firm, best for canning and cooking rather than dessertUF/IFAS lists it among the most fire blight resistant pears for Florida home gardens, and it is widely grown across the Gulf South and Texas. Two cautions on this row: the zone range is only the Florida recommendation and Orient is in fact grown well north of it, and the sources conflict on pollination - UF/IFAS lists it as needing no cross-pollination while Texas A&M calls the tree self-sterile, so plant a pollinizer. No chill figure is published in the extension source; Texas A&M describes the requirement only as low, in the range of 400 to 1200 hours. | Browse growers |
| Pineapple | very resistant to fire blight | Early Aug | 8-9 | hard and grainy, a canning and preserving pearUF/IFAS rates it very fire blight resistant. It is a hard pear, so treat it as a preserving variety rather than a dessert one. No chill figure is published in the extension source, so it is left blank rather than guessed. | Browse growers |
| Seckel | excellent (strong fireblight resistance) | Sept | 5-8 | tiny, intensely sweet, spicy; great for snacking and canningA tough, fireblight-resistant heirloom perfect for kids and canning; partially self-fruitful but crops better with a pollinizer — just not Bartlett or Potomac (cross-incompatible). | Buy $64.99 |
| Warren | resistant to fire blight | Late season | 5-8 | smooth and buttery with no grit, sweet and juicyFound in Hattiesburg, Mississippi by horticulturist T.O. Warren, which is the pedigree behind its fire blight resistance - it is the dessert pear for humid Southern summers where Bartlett blights out. | Buy $64.99 |
