GENERAL INFORMATION 
MODOWN" herbicide Is formulated as a flowable product containing 4 pounds of bifenox per gallon. MODOWN 
provides control of many broadfeaf and grassy weeds infesting soybeans. corn, grain sorghum. rice. small grains, 
and foreltry nursery seedbeds. 
In soybean •• MODOWN can be used alone or with Treflan. Lasso. Dual. Basalin. Prowl. Surflan andlor Lexone Or 
Sencor. These combinations controf a broader spectrum of weeds than when either prOduct is used alone. ;.--
MOCOWN can be appfied 8S 8 preemergent to both corn and grain sorghum alone or in combination with Lasso or ~ 
Dual; tn addition. the combination of MODOWN with Ramrod can be used in grain sorghum. ' WI 
U ... In rice Include preemergent. early postemergent and postflood applications. The early poslemergenl 
application can be made alone or in combinalion with propanii. 
Other regillered uses of MODOWN include postemergent applications in small grains a~d both preemergent 
and po.tame'gent applications to forest tree nursery seedbeds.

REDUCE-TILL OR MINIMUM-TILL SYSTEMS 
The above mentioned preemergent treatments recommended for conventional tillage systems may also be used 
when soybeans, grain sorghum or corn are planted in reduce-till or minimum-till systems. A contact herbicide (such 
8S paraquat or Roundup) should be used to control emerged annual weeds and grasses and for top kill and 
suppression of perennials. It is important that the MOD OWN spray mixture reaches the soil surface 10 create a 
chemical zone. To assure complete coverage, use the higher recommended spray volumes as the density of cover 
crop residue or weeds increases. See paraquat or Roundup labels for specific directions and precautions for use. 
Note: 
Do not apply MODOWN as e "cracking" or "spiking·· treatment. 
If rain does not occur within 7 days following application, a shallow cultivation or rotary hoeing is recommended. 
Cultivation will help control weeds which escape herbicide treatment. 
Rainfall which splashes MOOOWN treated soil onto the crop at time of emergence may result in crop injury. Leaves 
of plants may crinkle and discolor but injury is usually temporary. MOOOWN is not root absorbed. With good 
growing conditions. plants will recover quickly an': yields should not be affected. As plants \Jrow taller. their foliage 
is no longer subject to this type of injury. This temporary injury is less likely to occur on soybeans where MODOWN 
is surface mixed. 
In order to assure maximum safety and weed control, follow all cautions and limitations on this label and the labels of 
products used in tank mixtures with MODOWN.

RICE 
Gener.' InformaHon: 
MODOWN is a selective herbicide recommended as a preemergent. postemergent or postflood treatment. MODOWN 
can be applied either by air or ground equipment for postemergent or postflood treatment of rice. MOOOWN can be 
used either alone or in conjunction with propanilas specified in the following directions. Water management is a key to 
successful use of MODOWN. Maintaining soil moisture is important. Proper application is necessary to obtain good 
coverage and uniform distribution. For best results when MODOWN is applied as a preemergent surface treatment. 
there should be 8 good. well prepared seed bed. Large soil clods should be thoroughly broken up before application. 
When applied preemergent. MODOWN forms 8 chemical zone on the surface of the soil controlling weeds as their 
shoots come in contact with the herbicide while growing through the chemical zone. When applied postemergent 
MODOWN controls susceptible weeds by contact action and provides a 4 to 6 week residual. This may allow delay of 
flooding. When applied postflood. MODOWN controls susceptible weeds above the water level by contact action. The 
rate of MODOWN used per acre should be based on weed density. USE THE HIGHER RECOMMENDED RATE OF 
MODOWN WHEN INFESTATIONS OF THE WEEDS LISTED ON THIS LABEL ARE MODERATE TO HEAVY.

Apply MODOWN anytime after seeding until rice reaches early spike ~ tage and before the weed seedlings have 
emerged. For best results. apply to wet soil. Flush field if necessary to Yfet soil but drain field before application. 00 
not apply MODOWN to fields with standing water. Follow usual cultural practices after application. Fields with 
dayflower showing chemical symptoms or injury should be flushed to activate control ifdayflower reaches 2 to 3 leaf 0 
stage. Flushing field during dry periods may improve preemergent performance of MOOOWN.

minimum of 48 hours after "eatment before flushing or setting permanent flood. If permanent flood is delayed, 
flushing field during dry periods may improve residual preemergent performance of MODOWN until permanent 
flood is set. 
Reinfestation of the grassy weeds that propanil controls by contact action can be prevented by setting of permanent
