• Adhesives such as carboxymethyl cellulose, natural and synthetic powdery, granular or iatex-shaped polymers can be used in the formulations, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins and synthetic phospholipids.
• Other additives can be mineral and vegetable oils Dyes such as inorganic pigments, for example iron oxide, titanium oxide, ferrocyan blue and organic dyes such as alizarin, azo and metal phthalocyanine dyes and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc can be used.
• the formulations generally contain between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.
• the active compounds according to the invention can also be used for combating weeds, in a mixture with known herbicides, finished formulations or tank mixes being possible.
• a mixture with other known active compounds such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, is also possible.
• Solutions, suspensions, emulsions, powders, pastes and granules are used. They are used in the usual way, e.g. by pouring, spraying, spraying, sprinkling.
• the active compounds according to the invention can be applied both before and after emergence of the plants. They can also be worked into the soil before sowing.
• the amount of active ingredient used can vary over a wide range. It essentially depends on the type of effect desired. In general, the application rates are between 1 g and 10 kg of active ingredient per hectare of soil, preferably between 5 g and 5 kg per ha.
• Emulsifier 1 part by weight of alkylaryl polyglycol ether
• active compound 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.
• Seeds of the test plants are sown in normal soil. After about 24 hours, the soil is sprayed with the active compound preparation, so that the desired amounts of active compound are applied per unit area.
• the concentration of the spray liquor is chosen so that the desired amounts of active compound are applied in 10001 water / ha.
• the compounds according to Preparation Examples 6 and 11 show good compatibility with crop plants, such as, for example, wheat (0%), barley (0%), soybean (0% ) and cotton (0%), very potent against weeds such as Amaranthus (100%), Solanum (100%), Chenopodium (100%), Veronica (100%), sorghum (90%), Stellaria (95% ), Viola (99%), echinochloa (80%) and digitaria (100%) Ta bell e A 1: Pre-em ergence test / greenhouse
• Test plants which have a height of 5-15 cm are sprayed with the active compound preparation in such a way that the desired amounts of active compound are applied per unit area.
• the concentration of the spray mixture is chosen so that the desired amounts of active compound are applied in 1000 l of water / ha
• the compounds according to Preparation Examples 6 and 11 show better compatibility with crop plants, such as, for example, wheat (10%), barley (20%) and maize
