<p>Gametocidal pyridazinylcarboxylic acid derivatives The invention relates to novel pyridazinylcarboxylic acid derivatives of the formula (I) wherein R1 is hydrogen, a cation or C1-C6alkyl, Y and Y' are each independently an oxygen or a sulfur atom or a sulfinyl or sulfonyl group, R2 and R3 are each independently a C1-C12alkyl or C1-C12alkenyl group which is substituted by one or more halogen atoms, R4 and R5 are each independently hydrogen, halogen, nitro, cyano, C1-C6alkoxy, or C1-C6alkyl which is unsubstituted or substituted by one or more halogen atoms, and n is 0 or 1. These compounds have gametocidal properties and can be used for influencing generative plant growth and for producing male-sterile plants.</p> |
