1A	Sevin 80 S	carbaryl	1.25 - 2.5 lbs/acre	Apply as a basal directed spray with at least 30 gallons of water per acre.
1A	Sevin XLR Plus	carbaryl	1 - 2 qts/acre	Apply as a basal directed spray with at least 30 gallons of water per acre.
1A R	Furadan 4 F ("24-C")	carbofuran	1 pt/acre	Apply as a basal directed spray in 20-30 gallons of water. Do not make more than two foliar applications per season. Do not apply after heads emerge from the boot. Do not graze treated fields or cut for silage or forage within 30 days of treatment.
3 R	Warrior 1 EC	lambda- cyhalothrin	2.56 - 3.84 fl oz/acre	Direct spray to base of sorghum plants. Apply when chinch bugs begin to migrate into field. Repeat application at 3-5 day intervals if needed. Do not apply within 30 days of harvest. Do not apply more than 0.48 pts per acre per season. Do not apply more than 0.16 pints per acre after the crop reaches the dough stage.
1B R	Thimet 20 G	phorate	6 oz/1000 row ft	Apply by ground only over or at base of plants at cultivation, and cover with soil. One application per season. Do not feed foliage before grain harvest.
3 R	Baythroid 2	cyfluthrin	1.3 - 2.8 oz/acre	For best control, applications should be directed at the basal portions of the plant. A total of 3 applications may be made. Allow at least 10 days between applications and at least 14 days between the last application and harvest of grain or dry forage.
1B R	Lorsban 4E	chlorpyrifos	1 - 2 pts/acre	Apply 1/2 to 1 lb. a.i. (1-2 pints). The treated crop is not to be used for forage, fodder, hay, or silage within 30 days after application of 1/2 lb. a.i./acre,or within 60 days at rates above 1/2 lb./acre. Do not apply to drought stressed sorghum within 3 days following irrigation or rain. Do not treat sweet varieties of sorghum. Do not apply more than 11/2 lb. a.i./acre per season.
3 R	Mustang	zeta-cypermethrin	3.4 - 4.3 oz/acre	Begin applications when bugs migrate from small grains or grass weeds to small sorghum. Direct spray to the base of plants with sufficient spray volume to penetrate the soil/stem interface, leaf collars, and sheaths.
