Abstract
A dichloroquinolinic acid suspension as herbicide contains dichloroquinolinic acid (5-60%), emulsifier (5-12%), lignosulfonate as disperser (1-5%), Xanthan as thickening agent (0.1-0.5%), sodium benzoate as stabilizer (0.1-1.5%), n-butanol as defoaming agent (0.1-0.5%), JFC as penetrant (1-4%), glycol as antifreezing agent (1-6%), and water (the rest), and has advantages of high effect, low toxicity and cost and high safety for rice.
Description
The present invention relates to a kind of compound method of weed killer herbicide formulation, particularly herbicide for paddy field.
Paddy rice is the maximum cereal crops of China's cultivated area, and the crop smothering problem is the key factor that influences rice yield.Dichloro quinolinic acid is the special efficacy selective herbicide of control rice field main weeds barnyard grass grass, and is remarkably productive to the barnyard grass grass.Selectivity is strong, the amplitude broad in dispenser period, and a dispenser can be controlled the barnyard grass grass of whole growth period duration of rice, can also prevent and treat Monochoria vaginalis, Chinese celery etc.Dichloro quinolinic acid is wetting powder at present, and because of the suspensibility of its process equipment limits product is low, the performance of drug effect is subjected to certain influence.
The objective of the invention is to develop a kind of efficient, safety, this low dichloro quinolinic acid novel form of farming.
The present invention relates to the compound method of Dichloroquinolinic acid suspending agent, this agent consists of: dichloroquinoline acid content: 5-60% (by active ingredient), the newborn 34#5-12% of emulsifier farming, dispersant lignosulfonates 1-5%, thickener xanthans 0.1-0.5%, stabilizing agent Sodium Benzoate 0.1-0.5%, defoamer n-butanol 1-5%, penetrating agent JFC 1-4%, antifreeze glycol 1-6%, WATER AS FLOW MEDIUM supplies 100%, the preparation method: earlier dichloro quinolinic acid is made the middle product of high-concentration suspension agent, quantitatively centre product and auxiliary agent are added in the efficient homogeneous blender, after supplying water, carry out homogeneous again and disperse to form the 5-60% suspending agent, after the assay was approved, pack at last.
Advantage of the present invention is the drug effect height, and toxicity is low, and is easy to use to rice safety, and farming is originally low.
Accompanying drawing is a process chart of the present invention:
Embodiment is as follows:
Dichloro quinolinic acid 30%
The newborn 34# 8% of emulsifier farming
Dispersant lignosulfonates 3%
Thickener xanthans 0.3%
Stabilizing agent Sodium Benzoate 0.3%
Penetrating agent JFC 2%
Antifreeze glycol 4%
Defoamer n-butanol 0.2%
WATER AS FLOW MEDIUM supplies 100%
Metering takes by weighing above-mentioned various material, forms 30% dichloro quinolinic acid suspension emulsion after processing.
Through weeds center, academy of agricultural sciences, Jiangsu Province, unit field control effectiveness tests such as Xinyi City, Jiangsu Province plant protection unit, show that 30% Dichloroquinolinic acid suspending agent is to rice seedling bed, the barnyard grass grass of transplanting, seedling throwing field has preventive effect preferably, but the mu consumption only is 1/2 of a dichloro quinolinic acid wet-milling consumption (effective ingredient), mu restrains with 30% Dichloroquinolinic acid suspending agent 25-30, to the preventive effect of barnyard grass grass all more than 96%, and to rice safety.
Claims (2)
1, a kind of Dichloroquinolinic acid suspending agent is characterized in that the formulation composition, by active ingredient (W/W), be dichloro quinolinic acid 5～60%, the newborn 34#5 of emulsifier farming～12%, dispersant lignosulfonates 1～5%, thickener xanthans 0.1～0.5%, stabilizing agent Sodium Benzoate 0.1～0.5%, defoamer n-butanol 0.1～0.5%, penetrating agent JFC 1～4%, antifreeze glycol 1～6%, WATER AS FLOW MEDIUM supplies 100%, through being processed to form 5～60% Dichloroquinolinic acid suspending agent.
2, a kind of preparation method who realizes claim 1 Dichloroquinolinic acid suspending agent, it is characterized in that earlier dichloro quinolinic acid being made the middle product of high-concentration suspension agent, quantitatively centre product and auxiliary agent are added in the efficient homogeneous blender again, after supplying water, carry out homogeneous again and disperse to form 5～60% suspending agents, after the assay was approved, pack at last.
