This invention relates to a herbicidal composition comprising fosmidomycin or salt thereof in combination with the other herbicide selected from the group of ametryn or salt thereof or diuron, and to a method of killing weeds by applying to weed seedlings the said combination.
摘要:
This invention relates to (22R,23R,24S)-22,23-epoxy2.alpha.3.alpha.-isopropylidenedioxy-B-homo-7-oxa-5.alpha.-stigmastan-6-one which is of value as a plant growth regulator, a process for preparation thereof and a plant growth regulating composition containing the same.
摘要:
A plant growth regulator comprising as the active ingredients gibberellin and a jasmonic acid ester represented by the following formula (1): ##STR1## wherein R.sup.1 and R.sup.2 represent hydrocarbon groups. Gibberellin and the jasmonic acid ester are applied as a mixture, or as single agents each containing one of the two compounds, which are applied concurrently, or separately by a procedure wherein, while the earlier applied one is still in force, the other is applied.
摘要:
Brassinosteroid derivatives expressed in formula (I) and formula (II) ##STR1## and a plant growth regulator containing one type or two types of these brassinosteroid derivatives as active ingredient. The invention thereby presents novel brassinosteroid analogous compounds expressed in formula (I) and formula (II) and a plant growth regulator containing these compounds showing a persisting plant growth regulating action.
摘要:
A plant growth regulator comprising, as the active substance, one or more of N-substituted alanine derivatives of the general formula: ##STR1## wherein X represents halogen atom or trifluoromethyl, R represents hydrogen, straight chain or branched chain alkyl having 1-4 carbon atoms, alkenyl having 2-4 carbon atoms, an alkali metal atom or amine-forming residue, and n is zero or an integer of 1 or 2, with the proviso that when n is 2, X may be same or different, together with an inert carrier or diluent, in particular, an agent effective for controlling suckers of tobacco, and a process for regulating plant growth by using said plant growth regulator.
摘要:
Method for thinning young fruits and blossoms by applying to fruit trees, particularly citrus fruit trees an indazole compound of the formula: ##STR1## wherein R is hydrogen or a lower alkyl having 1 to 4 carbon atoms, and X is a halogen, or the salt thereof, and a thinning agent containing as the active ingredient the indazole compound as mentioned above.
摘要:
The present invention provides plant growth promoters each comprising, as an active ingredient, a jasmonic acid derivative represented by the following formula: wherein R1 represents a pentyl group or a pentenyl group and R2 represents a hydrogen atom or an alkyl group. These promoters exhibit excellent growth promotion effects particularly on root vegetables, potatoes (tuber crops), cereals, fruit vegetables, fruit trees, flowers and ornamental plants and industrial crops.
摘要:
The present invention provides a plant growth promoter comprising an epoxycylohexane derivative represented by the general formula: ##STR1## (wherein by R.sup.1 represents a hydrogen atom, C1 to C6 alkyl group or C3 to C6 cycloalkyl group, and R.sup.2 and R.sup.3 are independently lower alkyl groups or are combined to form a polymethylene group which may be substituted with an alkyl group) and gibberellin as active ingredients.
