One of the driest Julys on record is causing problems for some of B.C.'s most popular summer crops, including corn, peas and beans.

After less than a millimetre of rain fell on the Fraser Valley in all of July, the province's largest sweet corn grower expects that 40 per cent of the crop will be left on the field.

"We have three irrigation units running 24 hours a day, but we can't keep up, because the wind and the sunshine is sucking up the moisture," Opinder Bhatti of O'Bhatti Farm told CTV News.

"When you open up a cob you can see…. All the kernels have been dried. It has no flavour, no tenderness."

Bhatti also plowed under about 70 per cent of his pea and bean fields when hot temperatures hit earlier in July.

"They were cooking in the field. We couldn't harvest. They died," he said.

Brussels sprouts are also suffering in the Towneline Growers fields, where irrigation is both insufficient and costly.

"They're at least six to eight inches shorter than they should be," Towneline's Jerry Alamwala said.

"We've got two diesel (water) pumps running here right now and we're probably burning close to $1,000 a day in diesel."

But one crop is thriving in the Fraser Valley sunshine -- blueberries.

"The quality so far this year has been excellent, due to this wonderful weather we've been having," said Rhonda Driediger of Driediger Farms.

She added that B.C. growers across the province can expect a good crop of berries.

"I think we're looking at somewhere between 85 and 90 million lbs."
