CONTROL OF THE GL f; / ; THRIP 
Gladiolus are frequently infested with a thrip that feeds 
almost entirely on the gladiolus foliage and flower in 
the field and also winters over on the bulb in storage. 
This thrip does not winter over out of doors in the 
northern areas of the United States. 
Thrips may be introduced into a planting on infested 
bulbs or they may be carried into a planting on infested 
bloom from a neighbor. The adult thrip can fly short 
distances and a migration frequently takes place so that 
an infested planting at a nearby neighbor may be the 
source of your trouble. 
Elimination of the overwintering thrips on the bulbs can 
be secured by dusting the bulbs with a one, three or 
five per cent DDT dust. The bulbs should be thoroughly 
dried off after digging and then dusted with the DDT 
dust at the rate at one ounce of the dust to a bushel of 
bulbs. Place the bulbs in a sack with the dust and shake 
thoroughly, then empty the bulbs out in the storage 
trays. One dusting is all that is required. 
Thrips can be controlled on the growing plant with spray 
consisting of | oz. of tartar emetic, 2 oz. brown sugar 
to 3 gals. of water. Control can also be secured by 
spraying with a 1% DDT spray. Use 2!/5 oz. of a 50% 
wettable DDT powder ‘to | gal. of water, keeping thor- 
oughly agitated. Spraying to be effective must be thor- 
ough, both sides of the foliage must be covered with 
the spray material and the application should be made 
at regular seven to ten day intervals. 
A 5%, DDT dust is also effective in controlling thrips in 
the field. Dusting is not very effective unless a good 
hand duster is secured that will put out an even fine 
dust that will cover the foliage with a light uniform dust 
film. Repeat the dusting application at seven to ten 
day intervals. 
Dust or spray applications should be started when the 
plants are about six inches high if thrips are present. If 
no thrips are present on the bulbs at planting time, 
watch the plants closely during the growing season and 
start the control program at the first sign of gladiolus 
thrip infestation.
