1572999	Facility	Methyl Bromide storage for a large strawberry grower. May 1997
5411354	Symptoms	misshapen, distorted leaves
0541038	Damage	hydrogen flouride
1440086	Damage	Fatty alcohols (contact sucker control chemicals) turn small suckers brown shortly after application. Leaf axils may be burned by high concentrations of these alcohols. Buds of young plants may be killed. Leaf burn may be observed, particularly along the outer edge of tender upper leaves. Damage from these burns is usually minor, but it can be severe if the concentration of the chemical is excessive or the application is made to wilted plants. Leaf drop, shown in above photo, may occur at the bottom of the plant if the leaf axils have been severely burned.
0364088	Damage	hydrogen fluoride damage
2253071	Damage	Foliage "burn" due to dimethoate insecticide.
4912056	Symptoms
1440087	Damage	Maleic hydrazide , applied after topping to prevent sucker growth, acts by inhibiting cell division. If it is applied to immature plants, the younger leaves become narrow and pale green, and stalk elongation is slowed or halted. Application of excessive rates may cause abnormal coloring and thickening of upper leaves as well as drooping of the tip leaves. The use of excessive pressure and/or improper nozzles may result in leaf scorch or burn, especially on hot days. Suckers existing on the plant at the time of application develop small, narrow leaves and are limited in growth. Application rate determines the response of the plant.
1467030	Damage	diesel fuel spill
1440085	Damage	Other chemical substances such as oils, solvents, fuels, and diluents may cause injury to tobacco through foliar contact. This contact may result in darkening of tender leaf areas, distortion of the leaf, or the formation of necrotic areas on the leaf. Holes may appear in the leaf if the tissue is killed. Severe exposure may result in the loss of turgor, and/or leaf drop; but under normal circumstances, later growth is not affected.
1440084	Damage	Xylene is a chemical carrier that is present in some emulsifiable concentrate pesticides. When high rates of pesticides containing this chemical are applied under high pressure to young tobacco leaves, injury similar to a mild case of 2,4-D injury may be sustained. Leaves affected by xylene are slightly narrower than normal and may have a glossy appearance. Though similar to 2,4-D injury leaves affected by xylene are not as stiff.
1402091	Damage	Flumetralin (Prime +®) is applied at the late button to early flower stage of plant development to prevent sucker growth. If applied earlier, the tip leaves not removed by topping may exhibit symptoms similar to those caused by mosaic virus. There will be splotches of light and dark green leaf tissue. These young leaves may curl downward and do not fully expand. Buds of immature plants and affected suckers may cease growth. The tip end of the two outer leaves of each sucker may bend outward. Yellow residue of the chemical may be observed for several days after application. Occasionally, pith tissue will differentiate into adventitious buds, which appear as clusters of very small suckers. Suckers that escape contact with Prime+® will continue to grow.
1241650	Damage	Magnesium chloride dust abatement injury.
1402071	Damage	Xylene is a chemical carrier present in some emulsifiable concentrate pesticides. When high rates of pesticides containing this chemical are applied under high pressure to young tobacco leaves, injury is very similar to a mild case of 2,4-D injury. The leaves are slightly narrower than normal and may have a glossy appearance, but are not as stiff as those with 2,4-D injury.
1440076	Damage	Small irregular, oval- shaped lesions with a white-tan to brown-yellow appear on the margins of the bottom leaves. The lesions may progress to involve the entire interveinal area of the leaf as well as move up the plant, especially under dry conditions. With high concentrations of the chemical, the leaf edges may cup upward or curl downward, and the leaves may be narrow and arrow shaped. Stunting of the plants and premature flowering may also occur. Injury symptoms may be similar to those of manganese toxicity or triazine herbicide damage. Recommended rates and proper application may produce a mild flecking but rarely causes serious injury.
1402087	Damage	Fatty alcohols turn smaller suckers brown soon after application. Leaf axils may also be burned by high concentrations of the chemical. Occasionally, buds of young plants may be killed. There may be contact-type burns on the tender, upper leaves. Damage is usually minor, but can be more severe if the concentration of the chemical is excessive or if application is made to wilted plants. Usually there will be burns along the edge or other portions of the leaf where the spray material collects. Leaf drop may occur at the lower part of the stalk if burn in the leaf axil is substantial, leaves are large, humidity is high, and certain disease organisms are present. Excessive nitrogen fertilizer contributes to these conditions.
1402088	Damage	Maleic hydrazide, applied after topping to prevent sucker growth, inhibits cell division. If applied to immature plants, the younger leaves become narrow and pale green. Stalk elongation is slowed or halted. Application rate affects the degree of response. Applied at the correct rate and stage of plant development, the chemical has little visible effect on harvestable leaves, except for a slight yellowing of the upper leaves. Existing suckers at the time of treatment develop small, narrow leaves and are limited to growth. Suckers tend to develop at the bottom of the stalk as harvest nears completion. Excess rates will cause considerable yellowing, thickening, and drooping of the tip leaves.
1402090	Damage	Chlorpropham (Bud Nip®) is used for the prevention of late season suckers. It is applied to plants with fully expanded tip leaves. If applied earlier, the upper leaves exhibit more puckering than normal, which gives the leaves a "waffled" appearance. Suckers present at the time of treatment grow slowly and develop a rosette appearance, apparently because internode lengths are shortened.

5411360	Symptoms	Stunted, off-color foliage
5411361	Symptoms	Stunted, distorted, off-color foliage

1402089	Damage	Maleic hydrazide, applied after topping to prevent sucker growth, inhibits cell division. If applied to immature plants, the younger leaves become narrow and pale green. Stalk elongation is slowed or halted. Application rate affects the degree of response. Applied at the correct rate and stage of plant development, the chemical has little visible effect on harvestable leaves, except for a slight yellowing of the upper leaves. Existing suckers at the time of treatment develop small, narrow leaves and are limited to growth. Suckers tend to develop at the bottom of the stalk as harvest nears completion. Excess rates will cause considerable yellowing, thickening, and drooping of the tip leaves.

1467038	Damage	diesel fuel spill
1467214	Damage	boron damage
1402076	Damage	Oxamyl injury symptoms are very similar to the physiological disorder of frenching where affected plants develop a large number of leaves and suckers. The leaves are very narrow with prominent midribs. Interveinal chlorosis also occurs.
1402072	Damage	Xylene is a chemical carrier present in some emulsifiable concentrate pesticides. When high rates of pesticides containing this chemical are applied under high pressure to young tobacco leaves, injury is very similar to a mild case of 2,4-D injury. The leaves are slightly narrower than normal and may have a glossy appearance, but are not as stiff as those with 2,4-D injury.
1241648	Damage	Trees of several species died after calcium chloride dust abatement was applied to the road.
1467213	Damage	close up of 1467212
1402073	Damage	Carbofuran can cause small, irregular, oval-shaped lesions to first appear on the bottom leaves and progress upwards, especially under dry conditions. The white-tan to brown-yellow lesions are first produced on the leaf margins, followed by numerous lesions between the veins on the entire leaf. With high chemical concentrations, the leaf edges may be cupped upwards or curled downwards and the leaves may be narrow or arrow-shaped. Stunted plants and premature flowering may also occur. Recommended rates and proper application methods may produce a mild flecking but rarely the severe symptoms. Other disorders such as weather fleck and other chemicals may produce similar symptoms.
