Moisture carries the Norosac crystals into the upper layer of soil. Because of adsorption by soil particles, lateral movement is minimal. 4. Temperature and soil moisture activate the Norosac crystals and they begin to radiate a herbicidal barrier. This continues for an entire growing season, and the spent crystals disappear, leaving no 5. In this vapor barrier no plant cell division can occur. Seeds trying to germinate in the barrier will die. Sprouts below this zone will be killed as they try to penetrate the barrier. 6. Existing vegetation such as shallow- rooted grasses and annual weeds having root structures in this barrier will likewise be affected and die after two to three weeks. 7. Certain perennial weeds coming out of dormancy and attempting new growth within the Norosac barrier will run into the same dead end: they will be killed by the vapor. 8. Norosac. when used as directed, does not affect cranberry bushes that have deep roots extending well below the herbicidal vapor zone. How Norosac Reduces the Cost of Weed Control in Cranberries Its vapor barrier not only gives season-long control of toughest weeds, but can be applied anytime between late fall and the popcorn stage. The graphs above clearly dem- onstrate why Norosac is as effi- cient as any herbicide that has ever been offered to the Cran- berry grower. We urge you to study it carefully. Norosac provides season-long control of more than 40 tough weeds and grasses including ferns, rushes and sedges. The chemical cost per acre is low and the cost of
