Under the New Growth stage (% to VL> inch long) a combina- tion of Dieldrin and Malathion is recommended for the control of the blackheaded fireworm, false armyworm, weevil, yellow-headed tirewcrm, tip worm, cutworm, and Sparganothis fruitworm. Roughneck to Hook Stage in- cludes the period when the ter- minal buds have lengthened out an inch or more, giving the new growth a rough or scaly appear- ance, through to the time when the blossoms have hooked over just prior to the bloom. During this stage the Sparganothis fruit- worm must be controlled. A com- bination dust of DDT and Para- thion in recommended for this pur- pose. The warning found at the bottom of the chart should be carefully observed. Fungicides to control fruit rots include a new material known as Zineb. Applications to control these diseases should be made when the bog is 57r in bloom and followed by a second treatment in mid-bloom, or about 10-14 days later. Late Bloom (July 1-10) is the period when fruitworms are ac- tive. Malathion and combinations of Ryania and DDT have been added to the list of chemicals that will control this pest. Egg counts are still important in timing treatments. Dieldrin is recom- mended for the control of the new brood of weevils which appear in late bloom or about the time of the second fruitworm application. The 19,56 Weed Control Chart received considerable attention but only a few control measures were revised. It is suggested that Gen- eral Notes be cai'efully reviewed and that growers use the Weed Index to locate specific treat- ments. Control measures involving the use of PDB, Sodium Arsenate, Sodium Arsenite, and Ammate rave been omitted from the new chart. A caution should be noted under the Copper Sulfate treat-
