Pyrimidine -2-base) oxygroup) benzoyl) oxygroup) lauryl sodium sulfate.
Preferably, orthosulfamuron and the weight ratio of 2- pyrimidine oxy-benzoic acid derivative are 10:1 ~ 1:5.It is furthermore preferred that
Orthosulfamuron and the weight ratio of 2- pyrimidine oxy-benzoic acid derivative are 1:1,3:1 or 5:1.
The invention has the advantages that:
Two kinds of effective components show as synergistic effect in composition of the invention, and the activity of the composition is than using single compound
The expected summation of activity and single compound independent activity it is more significant.The composition has with strong complementarity, synergistic effect
Obviously, the features such as degrass spectrum expands, amount of application is reduced, high, environmental pollution reduces, is strong with environment compatibility to crop safety.
Specific embodiment
It elaborates below with reference to embodiment to specific embodiment provided by the invention.

It is uniformly mixed, obtains after the airflow crushes wettable by entering in mixer after above-mentioned formula in proportion coarse crushing
Property pulvis.
3 water dispersible granules of embodiment
Orthosulfamuron 30%, 2- pyrimidine oxy-benzoic acid derivative 10%, white carbon black 2%, lauryl sodium sulfate 3%, methyl naphthalene
Sodium sulfonate formaldehyde condensation products 4%, polycarboxylate 1%, calcium lignosulfonate 2%, di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate 1%, sodium carboxymethyl starch
1%, soluble starch surplus.
Above-mentioned formula is mixed in proportion, is crushed with micro jet, through mediating, subsequently into extrusion granulation
Machine is granulated, and after dry screening, water dispersible granules are made.
4 water dispersible granules of embodiment

Embodiment 5
Using orthosulfamuron as standard agent, disease index and control efficiency are calculated.Control efficiency is converted into probability value
(y), liquor strength (μ g/ml) is converted into logarithm (x), calculates concentration EC50 in virulence equation and inhibition with least square method,
The toxicity index grade co-toxicity coefficient (CTC) of medicament is calculated according to Sun Yunpei's Method.Orthosulfamuron and 2- pyrimidine oxy-benzoic acid are derivative
Object compounding the results are shown in Table 1 to the toxicity test of nutgrass flatsedge.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
B in the percentage composition+B medicament toxicity index * mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
Percentage composition
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] * 100
CTC≤80, composition show as antagonism, 80 < CTC < 120, and composition shows as summation action, CTC >=120,
Composition shows as synergistic effect.
The toxicity test interpretation of result of 1 nutgrass flatsedge of table
In table, X refers to orthosulfamuron, and Y refers to 12- ((5- methoxyl group -2- ((4- methoxy pyrimidine -2- base) oxygroup) benzoyl)
Oxygroup) lauryl sodium sulfate.
The result shows that orthosulfamuron and 2- pyrimidine oxy-benzoic acid derivative are between proportion 10:1 ~ 1:20, poison is altogether
Number illustrates that orthosulfamuron compounds preventing and kill off with aobvious to Amaranthus retroflexus with 2- pyrimidine oxy-benzoic acid derivative 120 or more
The synergistic function of work.
6 field control effectiveness test of embodiment
Medicament: herbicide prepared by embodiment 1 ~ 4,50% orthosulfamuron water dispersible granules.
Crop: rice.Rice seedlings grow fine, robust plant, without other pest and disease damages.
Control object: the weeds such as barnyard grass, clearvers, Veronica, Monochoria vaginalis, mexicana.
Test method:
According to the area of experimental plot, the good various medicaments of precise, and after being watered dilution, knapsack sprayer is utilized, is carried out
Even spraying.When spraying, it should be noted that the phenomenon that uniformly spraying application in experimental plot medical fluid, accomplishing no drain spray, more sprays.
20 days observation weeds death conditions after medicine, and the activity of weeding of more various medicaments.In addition, also to observe crop
Growing state, whether have phytotoxicity to investigate medicament to crop.
Test result:
2 field control effectiveness test result of table (after medicine 20 days)
It lives the results show that orthosulfamuron compounds to have to expand herbicidal spectrum and improve weeding with 2- pyrimidine oxy-benzoic acid derivative
Property effect, can effectively prevent and kill off broadleaf weeds and gramineae weed, preventive effect is better than the preventive effect of single dose, both illustrates compounding
There is significant synergistic effect to the preventive effect of broadleaf weeds in paddy field and gramineae weed.
The rice is doing well in each experimental plot, has no any medicine spot, illustrates that various medicaments are safe to rice.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise of not departing from the method for the present invention, can also make several improvement and supplement, these are improved and supplement also should be regarded as
Protection scope of the present invention.
