Agricultural Highlights



Orchards in eastern sections of the Big Island were in generally good condition. Warm days and adequate soil moisture benefited crop and fruit development. Field activities such as spraying, removal of leaves and lateral suckers were active. Black Leaf Streak disease incidences were observed in some fields. Oahu orchards were in fair to good condition. Windward fields remained in fair condition. A seasonal upswing kept leeward and central fields in active harvest. Irrigation levels were heavy. Orchards on Kauai were in good to fair condition. The dry weather and controlled irrigation benefited most orchards.


On the Big Island, light showers, warm temperatures, and sunny periods benefited fruit development. Younger fields made good growth in the Kapoho area. Fallowed fields in the Opihikao area were being prepared for new plantings. Field operations such as spraying for weeds and disease control, leaf trimming, harvesting were active during the week. Flowering and fruit set were generally good. On Oahu, fruit development and ripening were good due to increased day length and sunny conditions. Mealy bugs were mostly under control while Ring Spot virus lowered production in some fields. Orchards on Kauai continued to make fair to good progress. Spraying to contain insect populations was stepped up during calm weather to contain the increased infestations.


Head Cabbage

In the Big Island?s Lalamilo area, warm temperatures were not favorable for good head development. Warm days combined with irrigation contributed to an increase in disease incidence. New plantings made steady progress with heavy irrigation. Maui?s crop made steady progress despite the hot growing conditions. Increased irrigation was necessary and so far producers have made efficient use of water. Some fields were showing signs of increased stress especially those in the lower elevation areas. Insect pressure has increased slightly, but so far damage has continued to be minimal due to close monitoring and timely spraying by farmers. There have been reports of some losses due to wildlife feeding. Some fields on Oahu were abandoned to control the increasing pressure from the Diamondback moth infestation.

Dry Onions

Maui?s onion crop continued to make fair progress. Warm growing conditions were taking a toll on the crop. Older fields were struggling to develop good bulb size. In some fields, the heat stress has caused the plant to stop growing. Increased irrigation was helpful for some younger fields, but older fields have many factors to consider.

Sweet Corn

Weather conditions in windward sections of the Big Island were generally good for crop progress. On Oahu, harvesting was light after the holiday in July. However, supplies were heavy and new fields coming into production were making good progress. Light worm damage occurred during the week. Isolated fields in windward areas experienced growing problems and lower yields are anticipated from those fields.
