Abstract
The invention relates to a herbicidal combination containing ametryn and diuron. The herbicidal combination contains the ametryn and the diuron as active ingredients, the total weight of the ametryn and the diuron is 10 to 30 parts by weight, wherein the weight ratio of the ametryn to the diuron is 1:1 to 5, the herbicidal combination also contains Beta-cyclodextrin and urea as adjuvants, the total weight of the Beta-cyclodextrin and the urea is 5 to 10 parts, wherein the weight ratio of the Beta-cyclodextrin to the urea is 1 to 3:4. The herbicidal combination guarantees the synergism between the herbicides, and moreover, the time of weed control is shortened.
Description
Technical field
The invention belongs to agrochemical field, particularly relate to a kind of weeding pesticide composition that comprises interior ametryn and diuron, particularly relate to a kind of removing and comprise ametryn and diuron, also comprise the weeding pesticide composition of beta-schardinger dextrin-and urea.
Background technology
Ametryn (Ametryn) is a kind of triazine herbicide, also referred to as " ametryn ", is insoluble in water, be soluble in organic solvent, and it runs into strong acid and strong base and is decomposed into the 6-hydroxy derivatives without activity of weeding.
Diuron (Diuron) is the inner sucting conduction type broad-spectrum herbicide of ureas, the weeds that are mainly used in preventing and kill off noncrop area.Can be used for the Tanakas such as cotton, soybean, jowar, corn and prevent and kill off lady's-grass, eleusine indica, green foxtail etc.
Ametryn and diuron are composite has shown synergistic function on some weeds, but for most of weeds, is only that to have expanded weeding general, and for realizing effective synergistic function.
The present invention is surprised to find that by research the mixture of beta-schardinger dextrin-and urea can improve the herbicidal effect of ametryn and diuron Recompounded pesticide effectively, makes its synergy, and can increase by two kinds of agricultural chemicals solvability, improves the quick-acting phases of agricultural chemicals.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of weeding pesticide composition, particularly, the invention provides a kind of weeding pesticide composition that comprises ametryn and diuron, this composition pesticide comprises active component ametryn and diuron, the gross weight of ametryn and diuron is 10-30 weight portion, wherein the weight ratio of ametryn and diuron is 1: 1-5, this composition pesticide also comprises auxiliary agent beta-schardinger dextrin-and urea, the gross weight of beta-schardinger dextrin-and urea is 5-10 part, and wherein the weight ratio of beta-schardinger dextrin-and urea is 1-3: 4.
Preferably, above-mentioned composition pesticide can also comprise other active component, includes but not limited to methoxone, and wherein the parts by weight of methoxone preferably account for the 5-20% of ametryn and diuron gross weight, preferred, accounts for 10%.
Preferably, above-mentioned composition pesticide can also comprise other auxiliary agents, and surfactant for example, as the mixture of the single kind of anionic, nonionic, cationic surface active agent or multiple types.Surfactant is preferably one or more in alkyl phenol polyoxy ethyl ether, OPEO, polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether, polyoxyethylene trisiloxanes, castor oil polyoxyethylene ether, ethylene polyethenoxy ether.Described surfactant can be allowed a choice according to the application of agricultural chemicals, can add also and can not add.If add surfactant, surfactant accounts for the 20-40% of active component gross weight.
Preferably, above-mentioned composition pesticide can also comprise farm chemical carrier, and described farm chemical carrier is for can be used in arbitrarily the carrier that improves pesticide activity component solvability.Farm chemical carrier is preferably mineral oil and/or vegetable oil, and mineral oil is preferably paraffin oil, and vegetable oil is that soybean oil, peanut oil, cottonseed oil, rapeseed oil, palm fibre are put one or more in oil, cocoa butter, cupu oil.Preferably, farm chemical carrier accounts for the 30-100% of pesticide activity component gross weight.
It is 1-3 that the present invention also provides weight ratio: 5 beta-schardinger dextrin-and the composition of urea are for improving the purposes of weeding pesticide composition herbicidal effect, wherein said herbicidal effect refers to the rate of preventing and kill off that improves weeds, described weeding pesticide composition is the mixture of triazine herbicide and carbamide herbicides, preferably, Herbicidal combinations is the mixture of ametryn and diuron, and the weight ratio of ametryn and diuron is 1: 1-5.Preferably, in weeding pesticide composition, can also comprise active component methoxone.Wherein the parts by weight of methoxone preferably account for the 5-20% of ametryn and diuron gross weight, preferred, account for 10%.
Preferably, the present invention also provides a kind of weeding pesticide composition for sugarcane field, the ametryn that this composition pesticide comprises 2-15 weight portion, the diuron of 5-25 weight portion, the methoxone of 0-5 weight portion, the beta-schardinger dextrin-of 1-4 weight portion, the urea of 2-8 weight portion, the cottonseed oil of 10-20 weight portion, the ethylene polyethenoxy ether of 5-10 weight portion.
The present invention also provides a kind of weeding pesticide composition for preventing and kill off the purposes of sugarcane field weeds, the ametryn that wherein said weeding pesticide composition comprises 5-25 weight portion, the diuron of 2-15 weight portion, the methoxone of 0-5 weight portion, the beta-schardinger dextrin-of 1-4 weight portion, the urea of 2-8 weight portion, the cottonseed oil of 10-20 weight portion, the ethylene polyethenoxy ether of 5-10 weight portion.
The preparation method that the preparation method of the above-mentioned composition pesticide of the present invention applies this area routine is prepared into the preparation of various needs, can be by the direct mix and blend of simple method.
Weeding pesticide composition of the present invention has efficient preventive effect for the weeds of sugarcane field, the ratio of reasonably combined active component and active component thereof on the one hand, adopt simultaneously can enhanced activity composition management of weeds reinforcing agent, especially the mixture of beta-schardinger dextrin-and urea, herbicidal effect tool for triazines and carbamide herbicides composition is significantly improved, not only can guarantee synergy between weed killer herbicide, and the time shorten of management of weeds, as long as through spraying after described agricultural chemicals, the preparation that weeds are compared simple pesticide activity component has the more excellent speed of killing and kill efficiency.
