Excerpt from Agricultural Situation, Vol. 52: February 1968 Behind today's 'needs for chemical pesticides are the modern methods of farming which provide an environment ideally suited to Weeds, insects, and' crop diseases. Despite new tillage practices and the development of such things as insect and disease resistant crop varieties, nonchemical controls have not provided adequate alternatives. Thus, the'use of chemical pesticides has continued to grow. Value of pesticides formulated in all plants in the 48 States in 1964 amounted to $700 million. Sales aver aged more than per plant. Retail sales possibly exceeded $1 billion in 1964. Although insecticides have made up the lion's share of chemical pesticides produced, in dollar value, herbicides have made rapid inroads. While the insecticide share fell from 67 percent to 53 percent of total us. Shipments of pesticides between 1954 and 1964, the share of herbicides increased from 17 to 22 percent of shipments. At the same time, the share of fungicides dropped from 14 to 10 percent. But the others soil fumigants and conditioners, animal dips, and lesser unclassified pesticides more than doub-led their share, rising to 15 percent of the total.
