General Information
Apply Lightning D herbicide only on selected field corn hybrids (CLEARFIELD corn) warranted by the seed company to possess resistance/tolerance to direct application of certain imidazolinone herbicides. DO NOT apply Lightning D to corn hybrids that lack resistance/tolerance to imidazolinone herbicides. Contact your seed supplier, chemical dealer or BASF to obtain information regarding CLEARFIELD corn hybrids.
When applied as directed at the broadcast rate of 5.6 ounces per acre, Lightning D will control or reduce competition from the weeds listed in Table 1.
NOTE: R = Reduced Competition The number under Maximum Leaf Stage indicates the
MAXIMUM number of leaves at which weeds should be sprayed postemergence.
DO NOT count cotyledon leaves when determining weed stage of growth.

Mode of Action
Lightning D herbicide kills weeds by root and/or foliar uptake and rapid translocation to the growing points. Adequate soil moisture is important for optimum Lightning D activity. When adequate soil moisture is present, Lightning D 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.

Herbicide Resistance
Naturally occurring biotypes* of some of the weeds listed on this label may not be effectively controlled by this and/or other products with the ALS/AHAS enzyme-inhibitingmode of action. Other herbicide with the ALS/AHAS  enzyme inhibiting mode of action include the the sulfonylureas (e.g. Accen, Classic, Permi, Steadfas, Spirt, etc.) the sulfonamides (e.g. Python, etc.), the pyrimidyl benzoates (e.g. Staple, etc.), and the imidazolinones (e.g. Pursui, Scepter, Raptor, etc.). Herbicides
with the growth regulating mode of action include the benzoic acid herbicides (e.g. Banvel, Clarity, Oistinc, etc.), the phenoxyacid herbicides (e.g. 2,4-0, 2,4-DB, etc.) and the pyridine herbicides (e.g. Stingerz'). If naturally occurring biotypes are present in a field which are resistant to one of the herbicides in this premix and are not controlled by the other mode of action herbicide in this premix, Lightning D should be tank mixed or applied sequentially with an appropriate registered herbicide having a different mode of action to ensure control.
*A weed biotype is a naturally occurring individual within a given species that has a slightly different, but distinct genetic makeup from other plants. Lightning D is active against many broadleaf and grass weed species. For long term weed management, Lightning D contains three herbicides with two different modes of action to reduce the potential for selecting tolerant weeds (resistant weeds).

Crop Tolerance
Crops growing under stressful environmental conditions can exhibit various injury symptoms which may be more pronounced if herbicides are used. Corn plants treated with Lightning 0 may exhibit yellowing on new growth. Such effects occur infrequently and are temporary. Normal growth and appearance should resume within 1 to 2 weeks. Use of Lightning 0 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), Lightning 0 may cause injury to subsequent planted crops. See the ROTATIONAL CROPS GUIDELINE section of this label for recommended rotation intervals to sensitive crops.
