Abstract
The invention relates to the field of farm chemical weed killer, and particularly discloses a compound agent and a preparation method and application for preventing and killing off aquatic weeds in a sea cucumber culture zone. The compound agent for preventing and killing off the aquatic weeds in the sea cucumber culture zone comprises, by weight, 5-90% of prometryn, 0.5-5% of bensulfuron methyl, 5-10% of fatty alcohol-polyoxyethylene ether, 1-5% of lauryl sodium sulfate, and the balance of filler. The compound agent and the preparation method and the application for preventing and killing off the aquatic weeds in the sea cucumber culture zone have the advantages that two different machine-made agents are compounded, the dosage of one agent can be reduced, safety and resistance postponing of the aquatic weeds are benefited, effects of preventing and killing off the aquatic weeds are greatly improved, high efficiency, economical performance and time and labor saving are achieved, operating performance is strong, operation is rapid and thorough, and spirogyra and other weeds in the sea cucumber culture zone can be safely and effectively prevented and killed off to avoid severe even destructive damage to sea cucumbers.
Description
(1) technical field
The present invention relates to pesticide herbicide field, particularly a kind of compound drug and preparation method and application preventing and kill off culturing sea cucumbers district aquatic weed.
(2) background technology
Meat quality of sea cucumber is soft tender, nutritious, is typical high protein, low fat food, and flavour fat is beautiful, and local flavor is graceful, is the name food delicacies had long enjoyed a good reputation.Modern study shows, sea cucumber has improves memory, delays sexual gland aging, prevents arteriosclerosis and the effect such as antitumor.In recent years, way, China coast beach is risen and is built pool cultivated sea cucumber in a large number, has a extensive future.Generally; gather in the crops the sea cucumber needs time of 2 ~ 3 years in season; in holothruian cultures process; usually there will be the continuous aquatic weed such as Spirogyracommunis, the hydrodictyon reticulatum Hydroaictyon reticulatum winding of a large amount of seawater in culturing sea cucumbers district wraps around sea cucumber; not only polluted source; also seriously suppress the growth of sea cucumber, hinder sea cucumber results, sea cucumber even also can be caused to have no harvest.
The single dose of prometryn Prometyrn, bensulfuron-methyl bensulfron-methy is general only for dry land and agent for removing grass in paddy field in existing technology, and does not have the relevant report for preventing and kill off culturing sea cucumbers district aquatic weed or patent information.Some holothruian cultures district, applying mechanically paddy field chemical weed control method simply, abuse medicine drug abuse, there is bad poisoning in result again and again, and directly cause the sea cucumber underproduction even to have no harvest, some herbicidal effects are not good enough.Manually prevent and kill off culturing sea cucumbers district aquatic weed not only time-consuming but also not thorough, directly limit the development of holothruian cultures.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of high-efficiency and economic, saving of work and time, strong operability, quick compound drug and the preparation method and application preventing and kill off culturing sea cucumbers district aquatic weed thoroughly, safely and effectively.
The present invention is achieved through the following technical solutions:
Prevent and kill off a compound drug for culturing sea cucumbers district aquatic weed, be made up of the component of following percentage by weight: prometryn 5 ~ 90%, bensulfuron-methyl 0.5 ~ 5%, fatty alcohol-polyoxyethylene ether 5 ~ 10%, lauryl sodium sulfate 1 ~ 5%, surplus are filler.
In such scheme, preferred prometryn and bensulfuron-methyl weight ratio are 15: 1.
Described filler is diatomite.
This prevents and kill off the preparation method of culturing sea cucumbers district aquatic weed compound drug, comprises the steps:
By prometryn and bensulfuron-methyl mechanical mixture 30-60 minute, then add fatty alcohol-polyoxyethylene ether, lauryl sodium sulfate and filler and proceed mechanical mixture, mix 30-60 minute laggard row air-flow crushing, and then carry out secondary mechanical mixing, mix to detect after 30 minutes and qualifiedly namely obtain the compound drug that this prevents and kill off culturing sea cucumbers district aquatic weed.
Described filler is diatomite.
The formulation of compound drug of the present invention is wetting powder.
This prevents and kill off the application of culturing sea cucumbers district aquatic weed compound drug culturing sea cucumbers district aquatic weed control.
The beneficial effect of compound drug and preparation method and application that the present invention prevents and kill off culturing sea cucumbers district aquatic weed is: by the composite reagent of two kinds of different mechanisms, a kind of consumption of medicament can be reduced, contribute to safety and the resistance delaying aquatic weed, greatly improve the effect of aquatic weed control, high-efficiency and economic, saving of work and time, strong operability, fast thoroughly, can prevent and kill off culturing sea cucumbers district maritime interior waters silk floss safely and effectively waits weeds to carry out serious even crushing harm to sea cucumber.
(4) embodiment
