It is a fact well known that the application of certain herbicides in low concentrations, shortly before harvest, causes an increased formation of desired substances to plants; - such as carbohydrates. In this can. generally attributable to a reversal of the netabolism of the plant by the herbicidal composition, which runs at (sometimes accompanied by a vegetative growth retarded), there may be a pronounced incorporating sugar, starch and other produced significant metabolism. Some examples of compounds having said properties are described in the following publications: US patent 3,556 762, the of SA-of-bone 25, 28 867 and the 25, 57 139, but heretofore were previously not known such activity as regards substitution derivatives phénoxyaicanolques and 1 © cyclohexane dione derivatives.

The compounds of the invention provide for increasing the carbohydrate content in a large number of monocotyledonous and dicotyledonous plants, or their fruits. Examples include, for example, cane sugar confectioneries, sugar beet, grapes, melon, fruit, the ponune earth, corn, the various species millet (nervosum) and the fillings (clover and alfalfa). It in solvent borne coating if TE to elevated sucrose content in the case of sugar cane, sugar beet and species millet, the fructose content in the case of fruits and grapes, and the starch content in the case of other plants. The advantages thus achieved are obvious and do not require further details.

[80]

Their application for for influencing the content

[81]

in carbohydrates occurs at a later stage of plant growth that for their application as herbicides, since, at this stage the plants are much less sensitive to the action of herbicides at the stage of the lift, then they are supporting higher doses without damage. Advantageously, the active compounds are applied about one week confectioneries five months before harvest. After the lapse of time, the degree of maturity caused by the active material and, by consê° quvïit, the carbohydrate content, have reached a maximum. Π note that growth rate and duration of vegetation of different cultures can vary within wide limits. Thus the cane I-suere requires, depending on a locus and the climate, of 1 has 3 years to reach maturity. It must therefore assume the time. application to these conditions, time which may be between! and 13 weeks prior to réeolt © iaao the case of; sugarcane and sorghum soft "

The concentration of active substance of commercial formulations can vary within wide limits.

[88]

In wettable powders it is such as between about 10 and 951, balance formulation additives indicated above. In the emulsifiable concentrates it is between about 10 and 801. In the dusting agents it oscillates between 5 and H ealth spangle 201. In the content of active substance depends on, among other things, the physical state (liquid or solid) of said active material and the nature granulation agents, fillers andc, involved.

[89]

For the application, commercial products as concentrates are optionally diluted in the usual manner, for example with water in the case of wettable powders and of the emulsifiable concentrate. The dusting agents and, as well as spraying, do not need to be diluted with other inert substances prior to application.

[90]

The dose to be applied depends on external conditions, such as temperature, humidity and particularly the species the DS treated plant and its stage of development. Chroma in general, an amount such that the active material occurs in the natural growth process of the plant without being harmful to it. The dose may therefore vary in extended intervals, for example between 0,005 and 10 kg of active material per hectare. It may even be higher. In the case of plants latlfoliées, that are not endommaqées by the compounds of formula I, or which are only very little, the amount is preferably between 0.1 and 5, in particular between 0.5 and 2 kg/acre, while concentrations generally lower, ranging between 0.01 and 1 kg/acre, suffice in I® case of monocotyledonous plants.
