Citrus growers in the Rio Grande Valley are facing more threats than the cold this season: according to South Texas Citrus Alert, wind-driven rain is one of the main factors that spread citrus canker.

The bacterial infection, which can cause lesions on the leaves, stems and fruit of citrus trees, including lime, oranges and grapefruit, can destroy an entire harvest.

The Rancho Viejo area is under a canker quarantine. The Valley strain only infects limes and lemons, according to the Texas Department of Agriculture’s website.

Members with Texas Citrus Mutual fear wind and rain from Houston could spread a much more dangerous strain. “It would be devastating. Florida has had the canker for years and it’s troublesome,” said Dale Murden with Texas Citrus Mutual.

However, learned that the cold weather might be beneficial because at least it is impacting another threat in this region; the low temperatures tend to slow down the activity of the Mexican fruit fly, which causes citrus greening.
