Chemical herbicides are immediately applied to the sown seedbeds. These "pre-emergence" herbicides selectively kill the germinating weeds but do not harm the tree seedlings. If weeds become a serious problem later in the growing season, then a "post-emergence" herbicide is sometimes applied over the top of the seedlings. Unfortunately, not all weeds can be controlled with herbicides so nursery workers must remove them by hand-weeding. |

Preplant incorporated herbicides may cause injury when improperly applied or not uniformly incorporated. Lateral roots may appear to be pruned, stubby, or stunted. Main roots may have areas without lateral roots. Irregular growth with stunting of the affected plants is above ground evidence of this injury. The pattern of occurrence in the field may relate to application or incorporation methods which resulted in accumulation of herbicide in "hot spots." Soil residues from excessive and/or multiple uses of dinitroanaline pesticides on sandy, low organic matter soils may retard early season growth of the next crops. |

Triazines are a group of herbicides which include atrazine, cyanazine, propazine, ametryn, prometryn, simazine, and metribuzin. Substituted ureas are a group of herbicides which include linuron, diuron, fluometuron, and chloroxuron. Both triazines and ureas produce similar injury symptoms. Injury can be caused by foliar or root uptake. Mild symptoms from low levels first appear on the tips of older leaves as yellowing between the veins. As the injury increases, the areas between the veins turn brown and progress toward the base of the leaf. The leaves will die back from the tips and edges. Plants will be stunted but may survive from very low levels; however, plant death will occur from high levels. Foliar exposure can kill the plant; however, with low levels, yellow to white areas are formed, turn brown, and fall out. Ureas may produce a brighter yellow to white leaf mottling than triazines. Symptoms of injury from all herbicides in the triazine and urea groups are very similar and are difficult to separate. |

Injury symptoms from dicamba and picloram are identical but tobacco is much more sensitive to pircloram. Symptoms are somewhat similar to 2,4-D. Young leaves are often strapped, while the edges and tips of the leaves curl downward, giving a "parrot-beak" or "cobra-head" appearance. A small pointed tip usually protrudes from the end of the leaf. Leaf margins are not serrated as is common with 2,4-D. Severe injury is characterized by strapped and stubby young leaves. Bud leaves are often short and stubby with rounded tips. |

Preplant incorporated herbicides, such as dinitroanalines, may cause injury to tobacco when they are improperly applied or not uniformly incorporated. Typical injury symptoms include seriously pruned root systems which result in stunted root growth and irregular field appearance. Affected plants exhibit a deficiency of feeder roots in the zone of herbicide incorporation. Most secondary and feeder roots terminate in blunt knob-like tips. Injury is also more common when cool wet weather persists after transplanting, or when excessively high rates of herbicides are used. |

Phenoxy herbicides such as 2,4-D, dicamba, and MCPA on tobacco cause symptoms which vary with the herbicide rate and the age of the affected plants. Young leaves become stiff, puckered, elongated, and often have serrated edges. Midribs of affected leaves are prominent and may extend as a pointed needle-like projection or tail at the end of the leaf. Higher dosages cause the leaves to be "strappy" in appearance. High rates may also cause extensive twisting of stalks and leaf petioles. On older plants, leaf margins will curl downward, and the midrib will bend downward. |

Exposure of tobacco to contact herbicides such as paraquat and dinoseb causes white lesions on leaves and stems. The lesions turn brown and may fall out, leaving holes in the leaf. Low levels of exposure produce distinct individual lesions. At higher exposure levels, the lesions combine, causing the leaves to yellow and areas between the veins to die and fall out. If the plant does not die from the exposure, later growth will be normal. Weather fleck, contact injury by other herbicides, and some types of chemicals produce similar symptoms. |

Tobacco is extremely sensitive to picloram and very small amounts from drift, contaminated equipment, or residue in the soil will cause serious injury. The most common symptom is a downward curling of the margins and tips of the leaf. The curl of the tip results in "parrott beak" or hooded appearance. Symptoms appear first on young growing leaves, but due to the persistence of the compound, it will continue to affect the new bud leaves. New leaves may take on a heart-shaped appearance as the midrib is stunted, while the adjoining tissue continues to grow. Higher rates of picloram result in thick, strappy, elongated older leaves and elongated or aborted bud leaves. Young leaves may also have a wide thick midrib with little or no adjoining leaf tissue. Picloram residues may persist in the soil and cause damage to tobacco for periods of three or more years after application. |

The leaves show two primary symptoms:1- areas or blotches of necrotic tissue that is due to splashing of “Spartan” up onto the leaf. It is associated with highrates of the herbicide (or overlapping), wet prone soils, and/or a heavy rain preceding the onset of symptoms by a few days. These symptoms are usually seenon the older leaves and little or no symptoms on the younger ones. The plants will usually grow out of the injury sustained earlier in the season. Plants taking up enough herbicide to cause injury later in the season will be stunted and the leaves that are injured are not marketable. |
