摘要:
A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.
摘要:
Esters of 1,2-diphenyl-cyclohex-1-ene-4-carboxylic-acid are effective plant growth regulating agents. They are useful for controlling wild oats in cereal cultures and for growth inhibition in different cultures, e.g. for the inhibition of suckers in tobacco plants.
