METHOD FOR INCREASING LATERAL BRANCH, YOUNG BUD GENERATION, FLOWERING AND YIELD OF AGRICULTURAL AND HORTICULTURAL CROPS USING CERTAIN 2-(2-IMIDAZOLIN-2-YL)PIRIDINES AND QUINOLINES

摘要

PURPOSE: To increase the lateral branch difurcation, bud development, flowering and yield of agricultural and horticultural crops by applying a specific 2-(2- imidazolin2-yl)pyridine or quinoline compound. CONSTITUTION: A compound of formula I [R1 is an alkyl; R2 is an alkyl, a cycloalkyl; A is CHO, COCH3 , CN, CH3 , CH=NOH, a group of formula II; B is H, COR4 (R4 is an alkyl, phenyl, etc.), etc.; W is O, S; X is H, a halogen, OH, methyl; Y, Z are each H, a halogen, an alkyl, an alkoxy, phenoxy, NO2 , CN, phenyl, etc.; or when X is H, Y, Z together form (CH2 )n ((n) is 3, 4), a group of formula III (L, M, Q, R7 are each H, a halogen, an alkyl, phenyl, etc.)], its N-oxide or its acid adduct is applied to the leaves of agricultural or horticultural crops or the soil containing their seeds or sexual organs.
