Chemical Spot Disseminator: A new aid in reforestation

Dybar and Simazine used in combination have shown promise for chemical site preparation in spots where competition and frost damage cause heavy white spruce losses in clearcut areas. Three foot diameter spots treated in August 1968 in Ontario showed complete eradication of a wide variety of weeds. Spots thus treated, devoid of weeds with partial coverage all around, provide ideal conditions for early establishment of white spruce. Development of the Swastika Chemical Spot Disseminator in the spring of 1970 allows treatment of larger areas at relatively low cost.
