Abstract
The present invention relates to a kind of weed killer herbicide and manufacture method thereof, be specially the herbicide isoproturon and manufacture method thereof that are applied to paddy field, herbicides for use in paddy isoproturon, comprise isoproturon, auxiliary agent and filler, auxiliary agent is wetting agent, emulsifier, dispersant and protectant.Owing to the addition of the composition of the not same-action such as wetting agent, dispersant and emulsifier simultaneously in weed killer herbicide provided by the invention, with protectant acting in conjunction, protectant can effectively be worked.
Description
Technical field
The present invention relates to a kind of weed killer herbicide and manufacture method thereof, be specially the isoproturon single dose weed killer herbicide for paddy field and manufacture method thereof.
Background technology
Isoproturon is phenyl ureagroup herbicides, is mainly applicable to the nonirrigated farmlands such as wheat, corn, peanut, cotton at present and prevents and kill off grassy weed and most of broad leaved weed.
In the past author or inventor using the built agent of isoproturon as transplanted rice field and the weeding of live field, as phonetic in registered benzyl. isoproturon, this weed killer herbicide is mixed primarily of bensulfuron-methyl and isoproturon, isoproturon single dose registered and be used in paddy field and be not once reported, research shows that the vigor of phenyl ureagroup herbicides to the accumulation of rice seedling substance in vivo, root system can produce significant inhibitory action.In wheat and paddy rice interplanting farmland, after wheatland uses phenyl ureagroup herbicides, there is poisoning in rear stubble rice seedling, the high temperature time especially obvious sometimes.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of weed killer herbicide be made up of isoproturon single dose, being directly used in agent for removing grass in paddy field, and to rice seedling without causing evil effect, concrete technical scheme is as follows:
Herbicide for paddy field isoproturon, comprises isoproturon, auxiliary agent and filler; Described auxiliary agent is wetting agent, emulsifier, dispersant and protectant; Wherein isoproturon part by weight is 10-90%, described wetting agent part by weight is 0.1-15%, and emulsifier part by weight is 0.1-15%, and dispersant weight ratio is 1-20%, and protectant part by weight is 0.1-10%, and all the other are filler.
As preferred technical scheme, isoproturon part by weight is 50-70%, and described wetting agent part by weight is 0.2-10%, and emulsifier part by weight is 0.2-8%, and dispersant weight ratio is 2-10%, and protectant part by weight is 0.2-5%, and all the other are filler.
Wetting agent is fatty alcohol and derivative thereof or similar surfactant, the former pharmaceutically active ingredient of solid state in weed killer herbicide mainly can be made more easily to be readily wetted by water formation suspension, play a role after easily being absorbed by weeds.
Emulsifier is sulphonic acids emulsifier, mainly allows material not soluble in water in former medicine form emulsification liquid, gives full play to active ingredient in former medicine.
Dispersant is methyl naphthalene sulfonate formaldehyde condensate, can prevent the sedimentation that occurs at the former medicine composition of liquid and cohesion.
Protectant is to dimethylamino benzene diazosulfonic acid sodium, and protectant can avoid rice paddy seed or seedling to be subject to the growth inhibition effect of weed killer herbicide, available protecting rice paddy seed or seedling.
Filler is kaolin, diatomite solid kind, or solvent, such as water.
The production method of herbicide for paddy field Alon is:
(1) the former powder of isoproturon, auxiliary agent and filler are in the mixing of predetermined ratio, in mixer, mix and stir 50 to 60 minutes;
(2) pulverized by the airslide disintegrating mill of the mixture of uniform mixing through 0.7Mpa pressure, the size controlling of mixture is more than 400 orders;
(3) product of air-flow crushing is carried out mixed once again, reach former powder, auxiliary agent, filler fully mix in 400 order fineness.
High, the easy leaching of isoproturon solvability in water, isoproturon mainly weeds root absorption, and part cauline leaf absorbs, and is upwards transmitted to leaf, is distributed in blade tip and leaf margin more in conduit with moisture, play a role in green cell, it is the inhibitor of photosynthesis electron transmission, disturbs photosyntheticly normally to carry out, and can not release oxygen and carbon dioxide under light illumination, organic matter generates and stops, and responsive weeds are hungry and dead.Owing to the addition of the composition of the not same-action such as wetting agent, dispersant, emulsifier simultaneously in weed killer herbicide provided by the invention, the former medicine of isoproturon can be allowed to keep liquid, soil can be entered fast, by weeds root absorption.
Isoproturon lasting effect in soil is shorter than other phenyl ureagroup herbicides such as chlortolurons simultaneously, 20 days half life period of isoproturon single dose, and the chlortoluron half life period be 70 days short, owing to having wetting agent, dispersant, emulsifier in weed killer herbicide provided by the invention, former for isoproturon medicine is fully dissolved, isoproturon can be accelerated and decompose.
Paddy rice particularly japonica rice is different with accretion rate to isoproturon Assimilation and conductivity from weeds, and thus the susceptibility of paddy rice and weeds exists large difference, has added protectant effect, and isoproturon more can be avoided the impact of paddy rice.
The dispersant methyl naphthalene sulfonate formaldehyde condensate that dye industry uses is employed in herbicide for paddy field isoproturon provided by the invention, this dispersant mainly uses and dyestuff and concrete field, and the stabilizing agent of rubber industry latex, the auxiliary tanning agent of leather industry.But use at pesticide field and do not relate to, present invention uses this dispersant, simultaneously with wetting agent and dispersant acting in conjunction, can effectively weed killer herbicide be had good quality, stable storage.
The protectant added in weed killer herbicide; application is had in the weed killer herbicide of nonirrigated farmland cereal; but then also do not have for paddy field; different mainly due to environment for use; rice paddy seed or seedling easily come to harm because employing weed killer herbicide; produce to the growth of seed or seedling the evil even effect of leaf death of causing, under the environment having water, protectant is difficult to effectively play a role.Owing to the addition of the composition of the not same-action such as wetting agent, dispersant and emulsifier simultaneously in weed killer herbicide provided by the invention, with protectant acting in conjunction, protectant can effectively be worked.
Embodiment
Under greenhouse pot culture condition, carry out contrast experiment, adopt the weed killer herbicide of 7 groups of different formulations ratios and do not use the plantation situation of weed killer herbicide to contrast.Wetting agent is fatty alcohol, emulsifier alkyl naphthalene sulfonic acid formaldehyde condensation products sodium salt, and dispersant is methyl naphthalene sulfonate formaldehyde condensate, and protectant dimethylamino benzene diazosulfonic acid sodium, part by weight is as following table, and all the other are filler kaolin.
Planting experiment is rice seedlings, and wherein weeds are mainly monocotyledon weed barnyard grass.Spraying time is japonica rice, barnyard grass 2-3 leaf phase, starts to check after 25 days, and check result is as following table 1:
The Security of rice adding different amount safener in table 1 isoproturon measures
Upper table result illustrates, to rice injury obviously, add protectant, have and obviously improve the symptom that paddy rice hinders seedling, wherein injury rate and protectant usage amount have direct impact to unprotect agent isoproturon.As every hectogram is respectively 53.1%, 26.7%, 3.3%, 0.0% containing the seedling-damaging ratio of protectant 0.1,1.0,2.5,5.0 grams, when protectant content reaches 5%, paddy rice is no longer injured, and in view of this, addition is advisable with about 2.5%.
In table, result also illustrates, adding protectant has increase to prevent and kill off barnyard grass effect, if alone isoproturon herbicide effect ratio is with low 23.1% percentage point of protectant.
