Abstract
The invention relates to a weed-killing suspending agent compounded by benazolin and quizalofop-p-ethyl for pesticide. The weed-killing suspending agent comprises the following materials in percent by weight: 15-20% of benazolin, 15-20% of quizalofop-p-ethyl, 5-9% of surface active agent, 5-7% of propylene glycol, 0.05-0.15% of bentonite, 0.1-0.3% of methyl phenyl silicone oil, 0.01-0.03% of propylparaben and the balance of water. The weed-killing suspending agent has the advantages that the suspensibility is high, the long-time storage is stable, and grassy weeds and broad leaf weeds such as amur foxtail, American sloughgrass, chickweed and stellaria alsine.
Description
Technical field
The present invention relates to the composite agricultural chemicals weeding suspending agent of a kind of benazolin and Quizalotop-ethyl.
Background technology
Benazolin, English common name: benazolin ethyl; Benazolin, No. CAS: 3813-05-6, the chloro-2-oxidation of chemical name: 4-benzothiazole-3-guanidine-acetic acid ethyl ester.Be conductivity weed killer herbicide after a kind of specially effect property bud, after dispenser, plant absorbs transporting to whole plant corpus by blade, the same Vi par of the mode of action, and just drug effect performance is slowly.Sensitive plant is subject to growth retardation after medicine, and blade deadlock is green, thickens warp, Newborn Leaves distortion, and internode shortens, finally dead, similar to hormone herbicide symptom.
Quizalotop-ethyl, english common name: quizalofop-p-ethyl, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, No. CAS: 100646-51-3.Essence quizalofopethyl is a kind of novel dry land cauline leaf inorganic agent of high selectivity, has the selectivity of height between grassy weed and dicotyledonous crops, and the grassy weed in broad leaf crop field is had to good preventive effect.Essence quizalofopethyl speed of action is faster, and drug effect is more stable, is not subject to the impact of the environmental conditions such as rainwater temperature and humidity.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent claims again aqueous suspension agent, colloidal suspending agent, concentrated suspension, has cost low, produces, stores and transports and use the features such as safety, and easily mixing with water, easy to use.
Summary of the invention
For solving the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of benazolin and the composite agricultural chemicals weeding suspending agent of Quizalotop-ethyl.Specifically by following technical proposals, be achieved:
The agricultural chemicals weeding suspending agent that benazolin and Quizalotop-ethyl are composite, comprises the raw material of following weight percentage: benazolin 15-20%; Quizalotop-ethyl 15-20%.
The agricultural chemicals weeding suspending agent that benazolin and Quizalotop-ethyl are composite, is comprised of following materials by weight percentage: benazolin 15-20%; Quizalotop-ethyl 15-20%; Surfactant 5-9%; Propane diols 5-7%; Bentonite 0.05-0.15%; Methyl phenyl silicone oil 0.1-0.3%; Propylben 0.01-0.03%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of succinate sodium 2-ethylhexyl and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, by 40-60 weight portion succinate sodium 2-ethylhexyl and poly-(Oxy-1,2-ethylidene) non-ionic surface active agent composition of 40-60 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

Can also in formula, add according to actual needs pH adjusting agent.
The composite agricultural chemicals weeding suspending agent of benazolin of the present invention and Quizalotop-ethyl can adopt the general method in this area to be prepared, and one is ultramicro grinding method, and another kind is coacervation.
Concrete, described ultramicro grinding method:
(1) according to formula, benazolin, Quizalotop-ethyl, surfactant, propane diols, bentonite, methyl phenyl silicone oil, propylben and water are uniformly mixed to pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μ m.
(3) be placed in homogenizer homogeneous, make particle homogenising.
The composite agricultural chemicals weeding suspending agent of benazolin of the present invention and Quizalotop-ethyl has higher suspension rate, and long-term stable storage can effectively be prevented and kill off amur foxtail, be deceived grassy weed, the broad leaved weeds such as grass, chickweed, tongue of sparrow grass.
Embodiment
Embodiment 1
(1) according to formula, benazolin, Quizalotop-ethyl, surfactant, propane diols, bentonite, methyl phenyl silicone oil, propylben and water are uniformly mixed to pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μ m.
(3) be placed in homogenizer homogeneous, make particle homogenising.
The suspending agent making, the liquid of outward appearance thickness homogeneous phase, measures through Ma Erwen laser fineness gage, and its average grain diameter (D50) is 3 μ m.
Table 1: the agricultural chemicals weeding suspending agent formula table unit that benazolin and Quizalotop-ethyl are composite: kilogram
The agricultural chemicals weeding suspending agent that the benazolin of embodiment 1 and Quizalotop-ethyl are composite, is used in transplanting rape field, can effectively prevent and kill off amur foxtail, deceive grassy weed, the broad leaved weeds such as grass, chickweed, tongue of sparrow grass, dosage 900mL/hm
