CN1222055A - Herbicidal formulation and method of controlling plants - Google Patents

Abstract

A herbicidal formulation comprising a salt, such as a metal halide; a microbiological food, such as a carbohydrate; a detergent and an oxidant, such as hydrogen peroxide, all mixed into a solution with a diluent. The herbicide provides a method of controlling plants by applying to a target plant the formulation which then dessicates the plant and selectively promotes the growth of pathogens whereby the target plant is overcome and perishes.

Description

The method of Herbicidal formulation and controlling plant

The present invention relates to the method for Herbicidal formulation and controlling plant.

The invention particularly relates to and (but being not single-minded ground) to be used as environment amenable weed killer herbicide.For the purpose of explaining, will be with reference to the application of this respect.Yet, should be understood that use the composition of selecting according to such as the criterion rather than the environmental sensitivity of wide spectrum effect, attracting color or smell etc., the present invention also can be used in other the application.

The herbicidal effect of Herbicidal formulation is based on the systemic action of plant, thereby causes the destruction of the biological function of plant to cause the dead and rotten decomposition subsequently of plant.Weed killer herbicide stays harmful residue in soil and enter the flora and the fauna of survival usually, thereby causes the influence that is unfavorable for health and safety.In addition, synthetic mixed thing usually contains accumulabile uppity poisonous substance and toxin, as is present in a spot of polychlorinated biphenyl phenol among the defoliant that generally uses such as 24D and the 245T, or is referred to as reagent orange (agent orange).Traditional weed killer herbicide is not to be mixed by natural material to form, perhaps comprise at least a kind ofly to derive from synthetic active ingredient, and this synthetic material often and allergy, allergy and impairing one's health link together.

And traditional weed killer herbicide is not to be perfectly safe.The manufacturer of these mixed things only says just and does not know that traditional weed killer herbicide can work the mischief that this saying is not that this weed killer herbicide is harmless.

The objective of the invention is to improve above-mentioned one or more shortcomings and the method that uses reliable and effective Herbicidal formulation and controlling plant is provided.Another object of the present invention is to provide method non-internal-absorting, biodegradable environment amenable Herbicidal formulation and controlling plant.

At above-mentioned situation, to put it briefly, one aspect of the present invention provides the Herbicidal formulation that comprises following component:

Salt;

Microorganism food;

Washing agent and

Oxidant

These components are blended into solution with thinner.

Preferred this salt is metal halide, is that 125g/L is to saturated sodium-chloride water solution as scope.In preferred embodiments, this salt is 200g/L～300g/L and the more preferably sea salt of 250g/L.People will appreciate that the concentration of this salt is according to following factor, what promptly balance was determined between cost of salt (it reduces along with the concentration reduction) and the mixture efficient (it increases along with the increase of concentration).

Suitable microorganism food is carbohydrate, as sugar.This sugar can be the mixture of any sugar or sugar, as the sugar of known commodity aspartame by name, but preferably monose or disaccharide or the material that is closely related with it, and syrup form more preferably, as molasses, honey etc.The concentration range of sugar is preferably 15g/L～25g/L in the mixture.

Washing agent can be the be mixed any washing agent of formulation of weeding that is used for well known in the prior art, and its purpose is that (for example) makes on the surface of mixed thing attached to target plant, and (for the certain plants kind) destroys the wax coat of target plant appearance.Embodiment preferred comprises and contains the alpha-alkene sulfonate that the chain length scope is 12-14, yet, it should be understood that, preferred washing agent is fully biodegradable and environment amenable washing agent, other washing agent such as d-limonene or comprise its material, for example, the trade mark of being sold by Australian Citrus Resources is the washing agent of ORANGE SOUIRT.

The yet preferred environment amenable oxidant of oxidant as hydrogen peroxide etc., and does not preferably produce injurious effects to other composition that removes Herbicidal formulation.Also can use other oxidant, as alkali metal permanganate, subchloride, bichromate etc.

It will also be appreciated that additive can replace one or more of above-mentioned preferred composition if this additive includes preferred composition.For example: the organic concentrate of Roman chamomile (chamomile) draft can substitute alpha-alkene sulfonate because known it include alpha-alkene sulfonate.

On the other hand, the invention reside in the method that controlling plant is provided, thereby it is to realize by use the mixed thing that can make target plant dehydration and the growth of promotion pathogen that target plant is suppressed and wither to target plant.In these suitable mixed thing right and wrong absorption and comprise Herbicidal formulation as indicated above.

Another aspect, the invention reside in provides the Herbicidal formulation that contains following composition: ie in solution concentration enough makes salt, sugar and oxidant and the wetting agent of target plant dehydration, in case the concentration of this wetting agent enough ambassador's mixture can be wetting after target plant surface and the solution drying, is to be evenly distributed on the target plant substantially.Provide food and/or energy source thereby preferred sugar has enough concentration to spontaneous phytopathogen, but and then the target plant of attack dehydration, and target plant suppressed and wither.

If desired, can introduce or comprise the pathogene composition in the mixed thing, and mixed thing can be a biologically active.In addition, also can use non-diluent water,, increase the speed of mixed thing drying on target plant as alcohol, acetone etc.It should be understood, however, that selected solvent should be the solvent of sugar.

In order to make the present invention be easier to understand and produce actual effect, will explain typical embodiment of the present invention with reference to following embodiment of the present invention.

Embodiment 1

Preparation comprises 250g/L sea salt, 25ml/L cane suger, 10ml/L alpha-alkene sulfonate and 10g/L potassium permanganate solution, and is administered on the plant of kind listed in the subordinate list.After using Herbicidal formulation of the present invention, the height pathogene controlling symptoms that all following plants show all that the healthy and strong growing way of plant is obstructed and judge according to the experiment field.
