CONTROL IN PLANT BEDS
PREPLANTING SOIL TREATMENTS
To control	Insecticide and Formulation	Use per 100 square yards	Application Methods and Precautions
Flea Beetles	disulfoton (Di-Syston) 15% G	2/3 lb.	Apply evenly over bed area before seeding and work into the top two inches of soil. This material is highly poisonous to man if swallowed, inhaled, or absorbed through the skin. Tight bed frames and covers exclude beetles.
Green June Beetle Grubs	Methyl Bromide	9 lb.	Control of grubs is an added benefit when using methyl bromide for weed control.
CONTROL IN PLANT BEDS - ON PLANTS AFTER EMERGENCE			
Green June Beetle Grubs	trichlorfon (Dylox) 50% WP Parathion 1% D	1 lb. in 100 gal. water 2 lbs.	Apply Dylox or parathion when uprooted seedlings are first observed. Only sections of a bed may require treatment. Follow all label precautions.
Flea Beetles	carbaryl (Sevin) 50% WP	12 Tbsp.	The pre-planting application of Di-Syston should protect emerging seedlings since this is a systemic insecticide. DO NOT USE CARBARYL FORMULATIONS BEFORE THE 7-LEAF STAGE SINCE PLANT INJURY MAY RESULT. Lift off or roll back cover of bed before applying insecticides. Use at least three gallons of water per bed when preparing spray mixtures -- apply material thoroughly but lightly to plants. If Di-Syston was not used before seeding, it could be applied after plants emerge. Broadcast granules over the plants and water thoroughly to wash granules into the soil. Follow all label precautions.
	carbaryl (Sevin) 80% S	9 Tbsp.	
	carbaryl (Sevin) 4 lb./gal. F	4 Tbsp.	
	carbaryl (Sevin) 10% D	3/4 lb.	
	carbaryl (Sevin) 5% D	1 1/2 lb.	
	disulfoton (Di-Syston) 15% G	2/3 lb.	
			
Cutworms	trichlorfon (Dylox) 4% Bait	10 to 12 lb.	Use commercial preparation, or mix your own. To prepare, mix thoroughly 1/2 lb. of Dylox 80% SP with 10 pounds of corn meal. Broadcast bait in and around the plant bed. Wear rubber gloves when mixing and change clothing and bathe after handling this material.
Slugs	Metaldehyde Bait 3.2% or Parathion 1% D	2 lb. 2 lb.	Spread bait on ground (not on plants) in the evening. Apply dust evenly over plants and soil.
