This application discloses a method for increasing the recoverable sugar from sugar beet plants by applying to the sugar beet plants an effective amount of a compound having the structural formula: <IMAGE> wherein R is hydrogen, alkyl, alkoxy, hydroxy or hydroxyalkyl and R<1> is independently alkyl, alkoxy, hydroxy or hydroxyalkyl.
Description
SPECIFICATION
Method of increasing the recoverable sugar from sugar beets
This invention relates to a method of increasing the yield of sugar from sugar beets. More particularly, this invention relates to a method of increasing the recoverable sugar in sugar beets by treating the sugar beet plants during their growth period with benzamides of 2-methoxy-3,6dichlorobenzoic acid.
The performance of this process requires use of an effective amount of the benzamide at least two weeks before harvest. The benzamides of dicamba useful in the present method have the following structural formula:
wherein R is selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxy and hydroxyalkyl and R' is independently selected from the group consisting of alkyl, alkoxy, hydroxy and hydroxyalkyl.
It is most preferred that the alkyl substituents have a maximum of six carbon atoms.
The above described compounds can be prepared for example by reacting the corresponding acid chloride with the necessary amine as follows:
wherein R and R' are as defined above.
To effect the method of this invention, sugar beet plants are treated at a comparatively late stage of development with an effective amount of an active compound described above. This treatment is carried out during the stage of development of the sugar beet plant wherein sugar formation takes place. Thus, under normal growing conditions and common cultivation practice the active compounds described can be appiied to the sugar beet plants during the period of from about 2 to 10 weeks before harvesting and preferably during the period of from about four (4) to seven (7) weeks before harvesting. The use of nittogen fertilizer, when employed during the cultivation of the sugar beets, is advantageously discounted before the application of the active compounds of this invention.
The amount of the active compound of this invention required to effectively increase the recoverable sugar from sugar beets can very somewhat depending on such factors for example as the time of application, the weather and crop density. Generally, an amount of at least about 0.1 ounces per acre and preferably an amount of from about 0.5 ounces per about 20 ounces per acre can be used. While amounts greater than those mentioned can be used, they will not result in an advantage that would warrant their expense and are therefore not practical.
For practical use in treating sugar beets, the compounds of this invention are generally incorporated into compositions or formulations which comprise an inert carrier and an effective amount of such a compound. These compositions enable the active compounds to be conveniently applied to the sugar beets in any desired quantity. These formulations can be liquids e.g. solutions, aerosols or emulsifiable concentrates or they can be solids e.g. dusts, granules or wettable powders.
The preferred composition are liquid formulations, particularly emulsifiable concentrates.
Emulsifiable concentrates comprise an active compound according to this invention and, as the inert carrier, a solvent and an emulsifier. Such emulsifiable "concentrates can be extended with water and/or oil to any desired" concentration of active compound for application as sprays to the sugar beets. The emulsifiers most commonly used in these concentrates are non-ionic or mixtures of non-ionic with anoinic surface-active agents. With the use of some emulsifier systems an inverted emulsion (water-in-oil) can be prepared.
Solid formulations such as dusts, for example. can be prepared for example by grinding and blending the active compound with a solid inert carrier such as for example the talcs, clays, silicas or pyrophyllite, Granular formulations can be prepared by for example by impregnating the compound, usually dissolved in a suitable solvent, onto and into granulated carriers such as for example the attapulgites or the vermiculties, usually of a particle size range of from about 0.3 to 1.5 mm. Wettable powders, which can be dispersed in water or oil to any desired concentration of the active compound, can be prepared for example by incorporating wetting agents into concentrated dust compositions.
Typical formulations according to the present invention useful for increasing the recoverable sugar in sugar beets are illustrated in the following Examples wherein the quantities are in parts by weight.
EXAMPLE 1
Preparation of an Emulsifiable Concentrate
The following ingredients are blended thoroughly until a homogeneous liquid concentrate is obtained. This concentrate is mixed with water to give an aqueous dispersion containing the desired concentration of the active ingredients for use as a spray.
N-methyl-2-methoxy-3, 6-dichlorobenzamide 25
Sodium lauryl 2
Sodium lignin 3
Kerosene 70
EXAMPLE 2
Preparation of a Wettable Powder
The following components are mixed intimately in conventional mixing or blending equipment and are then ground to a powder having an average particle size of less than about 50 microns.
The finished powder is dispersed in water to give the desired concentration of active compound.
N, N-dimethyl-2-methoxy-3, 6-dichlorobenzamide 50
Fuller's earth 47
Sodium lauryl sulfate 2.5
Methyl cellulose 0.5
EXAMPLE 3
Preparation of a Dust
The following ingredients are mixed thoroughly and are then ground to an average particle size of less than about 50 microns to give a dust suitable for application with conventional dusting equipment.
N-hydroxy-2-methoxy-3, 6-dichlorobenzamide 10
Powder talc 90
The increase in the recoverable sugar from sugar beet plants by the application of the disclosed compounds was demonstrated by tests performed using a standard procedure. Sugar beet plants were sprayed with an approximately diluted emulsifiable concentrate of the test compound. The plants were surface irrigated at 2-week intervals to maintain normal growth. The crop was harvested and the recoverable sugar determined and measured on a percent basis in comparison to controls. The results of these tests are set out in Tables 1-4. Tables 5, 5A and 5B contain the results of a record test using the same procedures, but using four different times of applying N,N-dimethyl-2-methoxy-3,6-dichicrobenzamide.
