Plant Entry and Symptom Expression
Dichlobenil is a cellulose production inhibitor that works primarily on below-ground tissues but xylem transport to developing shoots may occur. This herbicide may be applied prior to or after weed emergence as it is absorbed through roots or young shoots. Dichlobenil is volatile and may be absorbed by any growing tissue.

What is dichlobenil used for?
is used for selective weed control in growing cranberries, ornamental flowers, orchard fruit, vineyards, and turf. It is available in wettable powder and granular formulations. It is a nonirritant in the Draize test, but it is a sensitizer in the maximization assay. The manufacture and formulation of dichlobenil was also associated with an outbreak of chloracne during the 1970s. This was perhaps due to a manufacturing contaminant that remained unidentified. Limited use of dichlobenil is reported in California, and there were no cases associated with its use included in the handler database.
What is 13% herbicide?
The 13% formulation is a category II skin irritant, but demonstrated no sensitization in the maximization test. The sethoxydim-associated case in the handler database (88-1253) was consistent with an irritant mechanism.
What is the 1,3 dipolar cycloaddition?
The 1,3-dipolar cycloaddition between a nitrile and a nitrile oxide gives direct access to the 1,2,4-oxadiazole nucleus (Equation 42 ). This is another well-established route to 1,2,4-oxadiazoles and was discussed extensively in CHEC (1984) <1984CHEC (6)365> and CHEC-II (1996) <1996CHEC-II (4)179>. The large upsurge in facile methodologies that rely upon carboxylic acid derivatives ( Section 5.04.9.1.2) has not been matched by an upsurge in 1,3-dipolar cycloaddition approaches, and the method appears to have fallen out of favor. The information on 1,3-dipolar cycloadditions of nitrile oxides to nitriles in CHEC-II (1996) <1996CHEC-II (4)179> and elsewhere <2004HOU (13)127> is, correspondingly, still very relevant.
What is a pre-emergent herbicide?

What is triazolopyrimidine sulfonanilide used for?
(triazolopyrimidine sulfonanilide) is an herbicide used only for corn and soybeans. The only irritation and sensitization studies involved a mixture of metolachlor (79.9%) and flumetsulam (2.6%). The mixture was a category II irritant in the Draize test and a sensitizer in the Buehler assay. There
Does dichlobenil inhibit cellulose synthase?
All indications are that isoxaben prevents an early step in the pathway, preventing the conversion of sucrose into UDP-glucose, whereas dichlobenil inhibits cellulose synthase enzyme complex, which cannot be directly assayed in vitro ( Figure 4 ). Inhibition of this enzyme results in inhibition of the in vivo formation of cellulose microfibrils. Lack of cellulose in young cells results in swelling of roots tips and cessation of growth as if treated with a tubulin-binding herbicide. No resistance has been reported to this herbicide class, and no crops have been engineered to be resistant to them.
What weeds are controlled by postemergence?
Temporary suppression of other perennials including yellow nutsedge, mugwort, quackgrass, and bind weed.
Is Dichlobenil volatile?
Highly volatile. Do not use in enclosed. In fine-textured soils, the leaching potential is low. In coarse-textured soils, leaching potential is moderate. Dichlobenil can move down a slope. Whether this occurs by mass action movement of granules or leaching of the active ingredient is unclear.

What chemicals are used to kill stumps?

If rain isn’t in the immediate forecast, most pre-emergent herbicide products call for watering to encourage the herbicide to seep into the soil and form a barrier against seed germination.
What to wear when applying pre-emergent herbicide?
Wear gloves, long sleeves, long pants, a dust mask, and eye protection during application. Apply on a calm day. This is more important when applying a liquid spray than granules.
