The cranberry season is several days advanced compared with last year. Insect activity has been about normal. Joe Kelley and the writer have yet to see a gypsy moth caterpillar in the areas treat- I'd during the last two years under the special aerial spray program. Growers should check their bogs during July for fruit worm, leaf- hoppers, weevils, spittle insects, and the second brood fireworms. A few suggestions for controlling these pests are outlined as follows: An accurate egg count is the key to proper timing of sprays and dusts for controlling fruitworm. Ryania is given first place in the list of treatments for this partic- ular insect (See tho insect and disease control chart). Leaf hop- pers are plentiful on many bogs and should receive special atten- tion. The new brood of weevils and the adults of the spittle insect will be found on bogs about mid- July or a few days earlier this year. DDT will control both of these pests. The control of ditch weeds is a topic that has received relatively little attention, but is an important part of good bog management. Dr. C. E. Cross has kindly prepared some very timely information on this subject, whicK i^ as follows: Notes on Ditch Weed Control One of the more neglected phases of cranberry bog management dur- ing the last three depressing years has been the cleaning of ditches. The actual digging out of silt, sand, and weeds is laborious ,,andi costly, and few growers at present can afford such care for their drainage and irrigation ditches. However, weed-choked ditches are often responsible for the production and distribution of many trouble- some bog woods, and under present conditions it is important that growers kill or burn off the weeds growing- in the ditches with some form of weedkiller. The knapsack sprayer is a very useful tool in this work, particular
