PRODUCT INFORMATION
Read all label directions before using. FOMESAFEN + IMAZETHAPYR SC is a selective herbicide which may be applied preplant, preemergence or postemergence for control or suppression of broadleaf weeds, grasses and sedges in soybeans.
FOMESAFEN + IMAZETHAPYR SC is generally most effective and consistent when used postemergence, working through contact action. Therefore, emerged weeds must have thorough spray coverage for effective control. Some bronzing, crinkling or spotting of soybean leaves may occur following a postemergent application, but soybeans soon outgrow these effects and develop normally. FOMESAFEN + IMAZETHAPYR SC also kills weeds by root and/or foliage uptake and rapid translocation to the growing points. Adequate soil moisture is important for optimum FOMESAFEN + IMAZETHAPYR SC activity. When adequate soil moisture is present, FOMESAFEN + IMAZETHAPYR SC will provide residual control of susceptible germinating weeds; activity on established weeds will depend on the weed species and the location of its root system in the soil.
Occasionally, internode shortening and/or temporary yellowing of crop plants may occur following FOMESAFEN + IMAZETHAPYR SC applications. These effects occur infrequently and are temporary.
Normal growth and appearance should resume within 1 to 2 weeks.
Optimum weed control is achieved by postemergent applications of FOMESAFEN + IMAZETHAPYR SC to young actively growing broadleaf weeds that are not under stress from moisture, temperature, low soil fertility, mechanical or chemical injury.
Certain germinating broadleaf weeds, grasses and sedges may be controlled or suppressed by soil residual activity from either preplant, preemergent or postemergent applications if rainfall occurs shortly after application. The extent and consistency of soil activity is dependent upon soil characteristics, ground cover, amount of rainfall following application and the rate of FOMESAFEN + IMAZETHAPYR SC used.

Information on Weed Resistance
Naturally occurring biotypes of certain broadleaf species with resistance to fomesafen and imazethapyr and related products (same mode of action) are known to exist. Selection of resistant biotypes, through repeated use of these herbicides, may result in control failures.
If poor performance cannot be attributed to adverse weather conditions or improper application methods, a resistant biotype may be present. In such a case, additional treatments with this herbicide or similar mode of action products are not recommended. Consult your local company representative or agricultural
advisor for assistance. When organophosphate (such as Lorsban) or carbamate insecticides are tank-mixed with FOMESAFEN + IMAZETHAPYR SC, temporary injury may result to the treated crops.
Use of FOMESAFEN + IMAZETHAPYR SC herbicide in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors make it impossible to eliminate all risks associated with the use of this product and, therefore, rotational crop injury is always possible. Under some conditions (such as heavy texture soil, high organic matter, low pH or low rainfall) FOMESAFEN + IMAZETHAPYR SC may cause injury to subsequent planted crops. Vegetable crops and particularly sugar beets are sensitive to FOMESAFEN + IMAZETHAPYR SC residues in the soil.
Replanting: If replanting is necessary in a field previously treated with FOMESAFEN + IMAZETHAPYR SC, the field may be replanted to soybeans. Rework the soil no deeper than the treated zone. Do not apply a second treatment of FOMESAFEN + IMAZETHAPYR SC.
