Description

The Herbicidal combinations that is used for the rice field
The present invention relates to be used for the Herbicidal combinations in rice field.More specifically, the present invention relates to comprise the benzoyl cyclohexanedione and the Herbicidal combinations that be used for rice field of some known herbicides compounds of weeding as active ingredient.
The benzoyl cyclohexanedione of weeding is known in WO 98/29406, WO00/21924, WO01/07422.The multiple compound that is disclosed in these documents has shown good control effect to weeds in paddy field.
Yet in practice, observe these compounds and rice is not shown gratifying herbicidal effect and/or phytotoxicity.In fact, use the benzoyl cyclohexanedione that is disclosed in these publications usually to have weak point.Therefore, its activity of weeding is not to be enough all the time, even perhaps activity of weeding is enough, but also observes the infringement that rice plants is not expected.
The activity of weed killer herbicide especially depends on the kind, rate of application, preparation of the weed killer herbicide that uses, noxious plant to be controlled, climate and soil conditions or the like.Another standard is the duration or the degradation rate of herbicide action.Optionally, also should consider of the change of the permanent noxious plant that uses or can take place for the susceptibility of active component in the specific geographical area.This change shows as the loss of herbicide action more or less and only can be remedied to a certain extent by increasing amount of application.
Consider a large amount of possible influence factors, in fact the single-activity composition does not have and is applied to the needed character of different purposes (particularly to noxious plant kind and climatic zone).In addition, continue the demand of existence to being effective with a spot of further herbicide application amount.Less amount of application not only reduces required absorption of active ingredient, but also reduces the consumption of needed auxiliary agent usually.The two has all reduced input economically and has improved the ecological friendly of using weed killer herbicide.
The method that is generally used for improving the purposes characteristic of weed killer herbicide is to provide other active component of required additional features to make up active component and one or more.Yet, when a plurality of active components are used in combination, usually can observe the incompatibility on its physics and the biology, for example be total to shortage, the degraded of active component or the antagonism of active component of preparation stability.On the contrary, compare, wish that acquisition has favourable action spectrum, high stability and high as far as possible synergistic function and then the active ingredient compositions that allows amount of application to reduce with the independent application of the active component that is mixed.
The purpose of this invention is to provide the Herbicidal combinations that is used for the rice crop, said composition has the character of compared with prior art improving.
The present invention relates to Herbicidal combinations, it comprises as the effective dose of active ingredient
