MEALY BUGS 
Mealybugs are small, sluggish, whitish, soft bodied insects, measuring up to '/4 inch long, found in 
clusters on the undersides of the leaves or in the leaf axils. 
INJURY. This pest sucks the juices from the stems and leaves, discoloring and deforming the foliage. 
CONTROL, Regular fumigations with calcium cyanide will aid in keeping mealybugs in check. The 
combination of Greenhouse Volck 1-50 and Nicofume liquid |-400 when applied when tempera- 
tures are below 90 degrees will give good results. Loro 1-800 and DuPont Spreader Sticker |-!200 
if sprayed when temperatures are not too high is very effective. The old method of syringing 
with water is still one of the easiest ways to keep the plants free of this insect. 
MITES 
Cyclamen mite and broad mite are often found on the same plants at the same time. Broad mite 
could pass through a complete generation in 4 to 5 days at 70 to 80 degrees while the Cyclamen 
mite will take 4 to 5 times longer. 
INJURY. Infested leaves become deformed, curl from the outside inward, and wrinkle so that pockets 
and pit-like depressions are formed. When the infestation is severe, the mites collect about the 
buds, causing them to blight. 
CONTROL. Thiocide |-200 and DuPont Spreader Sticker |-800 is the most effective control measure. 
We recommend spraying every week or ten days during the growing season, Nicotine liquid |-400 
plus spreader or No-Py-Ro 1-300 may also be used and will give fair control. Sodium Selenate is 
effective when applied in liquid form |/4 gram per square foot after plants are well established. 
RED SPIDERS 
There are several species of red spiders that attack the chrysanthemum, they vary. in color through 
yellow, orange and red. The body is oval in outline and bears eight well-developed legs. 
INJURY. Red spiders pierce the epidermis of the leaf and draw the liquid contents from the cells, 
causing the leaf to turn pale around the injured portion. They prefer to collect on the under 
surfaces of the leaves, which they cover with silken threads. 
CONTROL. Sprays that contain rotenone such as NNOR have given the best control. Moisture is 
detrimental to the development of the red spiders and frequent syringing washes them and their 
eggs off the plants. Loro |-800 plus DuPont Spreader Sticker |-|200 has given good control but 
should be applied with caution as it will injure foliage when temperatures are high. No-Py-Ro 
1-300 has also been proven to effectively control this pest. Sodium selenate is effective when 
applied in liquid form !/4 gram per square foot after plants are well established.
