Abstract
The invention relates to a herbicide, in particular to a combined weeding suspending agent. The combined weeding suspending agent is prepared by mixing Clethodim, Fomesafen, a solvent, an emulsifying agent, a stabilizing agent and a synergist together by a certain weight part. The combined weeding suspending agent does not use aromatic solvents, such as DMF (Dimethyl Formamide), carbinol and the like and uses natural botanical materials, and therefore, the combined weeding suspending agent is sate to use and transport, has small impact on the natural environment and significant efficacy and takes effect rapidly.
Description
(1) technical field
The present invention relates to a kind of weed killer herbicide, the agent of particularly a kind of combination Herbicidal suspension.
(2) background technology
Clethodim is a kind of inner sucting conduction type, and the cauline leaf inorganic agent of high selectivity can be prevented and kill off annual and perennial grassy weed, and to dicotyledon safety, it is synthetic to suppress the acid of plant body fat, plant strain growth is delayed, 1～3 all plant chlorisis necrosis after the dispenser.Fomesafen is a kind of soybean, peanut field herbicide after seedling with high selectivity, can prevent and kill off soybean, peanut field broad leaved weed and the rhizome of nutgrass flatsedge effectively, grassy weed is also had certain preventive effect, can be absorbed by weeds root leaf, make its rapid withered and yellow death, to soybean, peanut safety.Clomazone is a kind of inner sucting conduction type weed killer herbicide, long action time, and a drug drug effect can reach the crop whole growing, and administration time is flexible, cauline leaf processing behind the closed soil seedling before the seedling.
This three kinds of weed killer herbicide lists agent has a wide range of applications soybean Tanaka, it also is the main product on the market, the formulation of clethodim list agent registration has only missible oil, the formulation of fomesafen list agent registration be missible oil/microemulsion and aqua ， clomazone list agent registration be missible oil, microcapsules and microemulsion.And the weed killer herbicide in the market is that major part has all been used DMF making the creaming agent type, this kind solvent not only corrosivity is strong, cause the run, drip, leak in production and transport and the use easily, and the requirement to packaging material is also strict, increase the cost of manufacturing enterprise, the more important thing is, had bigger toxicity, easily people and animals are worked the mischief, thus severe contamination environment.
(3) summary of the invention
The present invention provides the combination Herbicidal suspension agent that a kind of drug effect is remarkable, speed of action fast, pollution is few in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
The agent of a kind of combination Herbicidal suspension comprises the raw material of following weight fraction: clethodim 0.5～20%, fomesafen 5～20%, solvent 20～50%, emulsifier 10～20%, stabilizing agent 1～5%, synergist 10%.
The present invention also can add clomazone in raw material, strengthen its drug effect, the weight fraction ratio of each raw material is: clethodim 0.5～10%, fomesafen 5～20%, clomazones 5～50%, soybean oil 20～50%, solvent 10～20%, emulsifier 10～20%, stabilizing agent 1～5%, synergist 10%.
Its preferred weight proportion is: clethodim 1～5%, fomesafen 5～15%, clomazones 10～25%, soybean oil 30～40%, solvent 15%, emulsifier 15%, stabilizing agent 1～5%, synergist 10%.
The present invention utilizes that fomesafen solvability in weak polar solvent is low, solvability is big in intensive polar solvent, clethodim He clomazone itself all be liquid and and the weak polar solvent physical property of dissolving each other, use skin grinder that fomesafen is ground to form certain fineness, add in clethodim, clomazone, weak polar solvent (perhaps water), synergist, stabilizing agent, emulsifier and other auxiliary agents, shear and obtain suspending agent.
Experimental results show that the suspending agent formulation is faster than missible oil formulation speed of action, drug effect is obviously good than missible oil.Suspending agent is after adding stabilizing agent, and the resolution ratio of clethodim reduces significantly, has guaranteed this acute holding time longer than missible oil, has saved cost.
Described solvent is soybean oil or water, and soybean oil is the one-level soybean oil or the soybean oil that methylates; Described stabilizing agent is organobentonite, white carbon or precipitated calcium carbonate; Described emulsifier is nonionic or anion surfactant; Synergist can guarantee the physical stability and the chemical stability of prescription.
Outward appearance of the present invention is an off-white color suspension, allows a small amount of layering through depositing 1 year, but shakes resilient.
The present invention has avoided aromatic solvents such as use DMF, methyl alcohol isopolarity solvent and dimethylbenzene, uses the natural plant material, and is safe in utilization, transportation safety, and little to natural environment influence, drug effect is remarkable, and speed of action is fast.
