Concentrates of I4X or over and over application i.iay cause some fruit russet, 

 especially near the machine. 



Excessive foaming may be reduced or prevented by adding the glyodin to the 

 tank when it is nearly full or by using 2 oz, of fresh spray lime or 1 pint of 

 kerosene per tank, 



Captan ; One of the newer materials virhich already has found a place in fruit 

 growing because of excellent scab control and excellent fruit finish. It is one 

 of the safest fungicides for easily russetted varieties, especially Golden Delici<-us, 



It controls Brooks' spot, and black rot, but not mildew, sooty mold, and 

 rusts. If rusts are a problem, use captan-ferbam combination, one half dosage of 

 each. 



It gives "kickback" up to 18 or 20 hours at 50°F, and also supression of spore 

 development on scab spots but no "bum out". For longer "kickback", up to 72 hours, 

 combine half dosage each of captan and phenyl mercury. 



It combines v/ith lead arsenate, DDT, and most other organic insecticides and 

 fungicides, but is incompatible with lime, oil, oil-type stickers and emulsifiable 

 insecticides such as TDE. Over application may cause spotting, yellowing, or 

 burning of leaves on Red Delicious, Baldvdn, and Stayman, especially around calyx 

 and first cover, 



Miacide A and Hiacide H: These are nev^ names for wha.t xvere formerly Vancide 

 A and Vancide M» They are scab protectants which are relatively new but vfhich 

 have given good control and good finish in tests and limited grovrer trials. 



Both Niacides are mixtures of several materials, Niacide A contains ferbam 

 and thiram along with other materials and is a dark wettable poiTder, Niacide M 

 has no ferbam in its formulation, but does have thiram. It is light in color. 



The manufacturer suggest Niacide A at 2 lbs, through first cover, I-I/2 lbs, 

 in second and third cover, and 1 lb, in later covers, but not closer than 30 days 

 to harvest and removal of excess residue at harvest. Niacide M.is suggested at 

 I-I/2 lbs, in early covers and 1 lb, in late covers in place of Niacide A for less 

 conspicuous residue with applications not closer than 30 days to harvest and re- 

 moval of excess residues at harvest. On spray sensitive varieties such as Golden 

 Delicious, Niacide M at 2 lbs, is preferred to A in pre-cover sprays, 



Thiram ; This fungicide has been knovm to agriculture for some time, but only 

 recently has it been seriously suggested for use on apples. It seems to have ex- 

 cellent scab control properties^ it controls rusts and other diseases, and produces 

 excellent finish. Its light color makes it suitable for summer and late season 

 use. There is still need for testing and observation londer a wider variety of 

 weather and grower conditions,
