Pesticide supplies for the 1980 crop season should be adequate to meet overall farm needs. Net supplies should be about 2 percent greater than last year, and prices about 10 percent higher. Manufacturers' insecticide supplies are off by 3 percent, but there are larger, than normal stock carryovers for distributors, dealers, and farmers. Farmers’ herbicide requirements will rise about 2 to 5 percent this year. Insecticide use is likely to be up 8 to 10 percent over 1979’s abnormally low levels.
