Abstract
The invention discloses herbicide for a forest. The herbicide is prepared from, by content amount, 1 g of 4, 4'-dipyridyl, 5 ml of bromoethane and 15 ml of acetonitrile. The herbicide is stable in property, long in lasting period, wide in herbicide controlling spectrum, capable of efficiently killing annual gramineous weeds and also capable of preventing and killing annual broadleaf weeds, does not pollute a water source, and is low in toxicity for people and animals, safe to use, good in weed killing effect achieved rapidly, and low in cost.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, particularly a kind of woods weed killer herbicide preventing and treating crop field weed.
Background technology
Weed killer herbicide also known as weedicide, in order to eliminate or to suppress a class material of plant growth.Effect is by the impact of weed killer herbicide, plant and environmental condition Three factors.Be divided into by effect go out natural disposition and selective herbicide, conventional kind is organic compound.The noxious plants such as the ground weeds such as control farmland, orchard, floral nursery, grassland and uncultivated area, railway line, river course, reservoir, warehouse, assorted filling, assorted tree can be widely used in.
China rural area, along with science and technology is tilled the land the material benefit brought to peasant, the use of weed killer herbicide is more and more subject to the favor of peasant.But prevent and kill off multiple weeds owing to using merely a kind of weed killer herbicide to be difficult to, simultaneously certain weed killer herbicide alone for a long time, weed community also can be caused to change, some weeds is suppressed, and other weeds rise to sociales or malignant weed by original non-principal status, certain weed killer herbicide alone also can strengthen resistance weed gradually for a long time in addition.
Summary of the invention
Main purpose of the present invention is to overcome above-mentioned deficiency existing in prior art, provides an elite stand weed killer herbicide.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
One elite stand weed killer herbicide, described weed killer herbicide comprise following raw material mixing composition: 4,4 '-bipyridyl, bromoethane, acetonitrile.
As preferred technical scheme, described raw material by component amount is: 4,4 '-bipyridyl 1g, bromoethane 5ml, acetonitrile 15ml.
As preferred technical scheme, described weed killer herbicide preparation method is as follows:
(1) in 50ml round-bottomed flask, 4 are added, 4 '-bipyridyl 1g, bromoethane 5ml, acetonitrile 15ml and stirrer, add hot reflux 2h in oil bath after, cooling, collecting by filtration;
(2) obtained a small amount of yellowish-brown paraquat weed killer herbicide particle, is mixed with the aqueous solution of 20%, weed killer herbicide finished product.
Beneficial effect:
The present invention is a kind of stable in properties, has the longer lasting period, broad weed-killing spectrum, efficient to annual gramineous weed, annual broadleaf weed can also be prevented and kill off, not polluted source, to people, animal low toxicity simultaneously, use safety, herbicidal effect is good and fast, the weed killer herbicide that cost is low.
Embodiment
Below in conjunction with specific embodiment, the present invention is further described, so that those skilled in the art more understands the present invention, but does not therefore limit the present invention.
