- Solid carriers are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bolus, loess, clay, dolomite, diatomaceous earth, calcium and magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, Ammonium nitrate, ureas and vegetable products such as corn flour, tree bark, wood and nutshell flour, cellulose powder or other solid carriers.
- mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bolus, loess, clay, dolomite, diatomaceous earth, calcium and magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium s
- the concentrations of the active ingredients I in the ready-to-use preparations can be varied over a wide range.
- the formulations contain from about 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of at least one active ingredient.
- the active ingredients are used in a purity of 90% to 100%, preferably 95% to 100% (according to the NMR spectrum).
- Dissolved mixture consisting of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and
- Mixture made up of 80 parts by weight of cyclohexanone and
- Wettol J EM 31 nonionic emulsifier based on ethoxylated castor oil; BASF AG. A stable emulsion concentrate is obtained.
- the active ingredients I or the herbicidal compositions can be applied pre- or post-emergence. If the active ingredients are less compatible for certain crop plants, application techniques can be used in which the herbicidal compositions are sprayed with the aid of sprayers in such a way that the leaves of the sensitive crop plants are not struck wherever possible, while the active ingredients on the leaves underneath are growing undesirably Plants or the uncovered floor area (post-directed, lay-by).
- the application rates of active ingredient I are 0.001 to 3.0, preferably 0.01 to 1.0 kg / ha of active substance (a.S.) depending on the control target, the season, the target plants and the growth stage.
- the substituted 2-phenylpyridines I can be mixed with numerous representatives of other herbicidal or growth-regulating active compound groups and applied together.
- 1,2,4-thiazadiols, 1,3,4-thiadiazoles, amide, aminophosphoric acid and its derivatives, aminotriazoles, anilides, aryloxy- / heteroaryloxyalkanoic acids and their derivatives, benzoic acid and their derivatives, benzo come as mixing partners - thiadiazinone, 2 - (hetaroyl / aroyl) - 1, 3 -cyclohexanedione, heteroaryl-aryl-ke one, benzylisoxazolidinones, meta-CF-phenyl derivatives, carbamates, quinoline carboxylic acid and their derivatives, chloroacetanilides, cyclohexane-1, 3 -dione derivatives, diazines, dichlor
- the white crystals obtained (5.8 g) were further purified by stirring with MTB / petroleum ether (1: 1) Yield: 5.2 g (27%), mp: 184-185 ° C.
- Plastic flower pots with loamy sand with about 3.0% humus as substrate served as culture vessels.
- the seeds of the test plants were sown separately according to species.
- the active ingredients suspended or emulsified in water were applied directly after sowing using finely distributing nozzles.
- the tubes were lightly sprinkled to promote germination and growth, and then covered with clear plastic hoods until the plants had grown. This cover causes the test plants to germinate evenly, unless this was affected by the active ingredients.
- test plants For the purpose of post-emergence treatment, the test plants, depending on the growth habit, were first grown to a height of 3 to 15 cm and only then treated with the active ingredients suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers or they were first grown separately as seedlings and transplanted into the test containers a few days before the treatment.
- the application rate for post-emergence treatment was 0.0313 or 0.0156 kg / ha a.S. (active substance).
- the plants were kept in a species-specific manner at temperatures of 10 to 25 ° C and 20 to 35 ° C.
- the trial period lasted 2 to 4 weeks. During this time, the plants were cared for and their response to each treatment was evaluated.
- the plants used in the greenhouse experiments are composed of the following types:
- the young cotton plants were dripping wet with aqueous preparations of the active ingredients (with an addition of 0.15 wt -.% Of the fatty alcohol alkoxylate Plurafac LF 700 ® 2), based on the
- Spray broth treated with leaves.
- the amount of water applied was the equivalent of 1000 l / ha. After 13 days, the number of leaves dropped and the degree of defoliation in% were determined.
