Manitoba Tuber Set Numbers Looking Good


With temperatures having hit the upper 20 C range and the low teens overnight, it has been good for tuberization of Manitoba potato crops, the July 29 provincial potato report from Manitoba Agriculture’s Vikram Bisht said. In many fields the tuber set numbers appear to be good.

In most places rains are meeting crop water demands reducing the need for irrigation, the report noted. Cumulative rainfall in potato growing areas ranges from just above 100 to nearly 200 per cent of the 30-year normal.

The frequent rains have increased the late blight risk, Bisht said in the report. The spore traps from all 14 site-samples submitted were found to be negative for late blight spores though.

“Even in the absence of spore being trapped, scouting in wind-protected or unsprayed spots in fields is important,” Bisht said in the report.
