ACRE concluded that once the GM potatoes had been harvested on each trial site , the ground should be left fallow to encourage the germination of true potato seed . The U.S. Environmental Protection Agency allows lindane seed treatments on barley , corn , oats , rye , sorghum and wheat . According to organic producers , many viable non-chemical alternatives to lindane seed treatment exist , including crop rotation , early planting , reduced tillage , clean cultivation , UV light traps and winter plowing , among others . Only feed seeds or foodstuffs approved for livestock or human consumption . True potato seed is long-lived but readily germinates under appropriate conditions , however , the volunteer potatoes from true seed are extremely vulnerable to herbicide application . Occasionally alpine larch seeds in and regenerates on a burned area within the subalpine forest , 100 to 150 m ( 330 to 490 ft ) below its usual elevational limits . At the same time , a number of application methods including in-furrow , broadcast granular or spray formulations , potato seed piece treatments , and attract and kill strategies will be assessed . Alfalfa producers across the midwest , including Ohio , are successfully spring seeding alfalfa without a small grain . Using herbicides to control the weeds at establishment is a necessary procedure when spring seeding alfalfa alone .
