and rot can continue in harvested fruit before and after 

 it is marketed. 



Fungicide applications should start about three weeks 

 before harvest and be repeated as needed until fruit is 

 harvested. A repeat spray may be 7 days or longer after 

 a previous spray if there is little or no rain or 3 to 5 

 days if there is much rain. The fruit should be protec- 

 ted at all times during this period. It is no time to 

 take chances. 



Satisfactory fungicides, with pounds to 100 gallons 

 of water and with days to harvest (dh) or no time limit 

 (NTL) when last application is allowed, are: Captan, 50% 

 WP; 2 lbs (NTL); thiram, 65% WP, 2 lbs (7dh); sulfur, 95% 

 WP, 5 lbs (NTL); and benomyl , 50% WP, 1/2 lb (NTL). 



Sulfur applied closer than 10 days to harvest may 

 leave objectionable residue. No more than two sprays of 

 benomyl should be applied during this period. 



Rhizopus rot (a grayish black mold) causes rot of 

 harvested fruit. Botran*, 75% WP controls it but does 

 not control brown rot. Both rots - brown rot and Rhizopus 

 rot - can be reduced on harvested fruit if the last spray 

 on the tree, 1 to 3 days before picking, is a mixture of 

 captan, 1 lb plus benomyl, 1/2 lb, plus Botran*, '2/3 lb. 



Harvesting Suggestions 



The hand which touches or handles a fruit with brown rot tran- 

 fers spores to healthy fruit handled later and increases post-har- 

 vest rot. 



Fruit picked into new baskets will not become contaminated by 

 the containers, but containers that are used over and over again 

 will become contaminated with spores and will increase post-harvest 

 rot. Decontaminate them by dipping or spraying them, inside and 

 outside, with captan, 2 lbs to 100 gallons of water, at the begin- 

 ning of each day they are used.

Influence of timing of bee hive introduction on production of high- 

 bush blueberries : The relationship between the time when bee hives 

 were brought into the planting and the productivity of 'Jersey' 

 blueberry was studied by G.S. Howell et al . at Michigan State Uni- 

 versity, East Lansing, and reported in Volume 7 (No. 2) of Horc 

 Science . Their findings suggest that early pollination is asso-
