The biological test example

When the effect of active compound combinations surpasses the summation of the effect when each reactive compound is used separately, there is synergistic function.The predictive role of the particular combinations of two kinds of reactive compounds can use so-called " Colby formula " (referring to S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) following calculating: if

X be when use consumption as mg/ha or concentration the activity during as the reactive compound A of mppm;

Y be when use consumption as ng/ha or concentration the activity during as the reactive compound B of nppm, be expressed as the percentage that accounts for untreated control;

E be when use consumption as m and n g/ha or concentration the activity during as the reactive compound A of m and n ppm and B,

So

If the activity of actual observation (O) is greater than expection active (E), so said composition super add and, promptly have synergistic effect.

The foregoing description is several preferable compound mode of Herbicidal combinations collaborative among the present invention, in order to embody beneficial effect part of the present invention, below we will test the collaborative Herbicidal combinations of allocating in the foregoing description.

Invention main points of the present invention provide several preferred implementation below in order better to explain.

The inventor is by a large amount of screening tests, the different proportionings of penoxsuam and Flumetsulam test and preventive effect analysis have been carried out a large amount of, discovery is in certain ratio range, resulting Herbicidal combinations has the synergistic effect effect, and be not only the simple addition of two kinds of medicaments, be illustrated with following biologicall test example.

Test 1: to the evaluation of composition activity of weeding behind bud under the condition of experimental field

Method:

These tests are carried out in dragon lantern chemical test field, Jiangsu.Thereby maize planting is used normal conventional practice to be used to apply fertilizer, sow and is safeguarded the good growth of guaranteeing crop and weeds.This test adopts conventional research method to carry out.The splat of test is that 2 to 4.5 meters wide * 5.5 are meter to 10 meters long.All inorganic agents use all at random fully that group experimental scheme in district's applies, and wherein each inorganic agent repeats 3 or 4 times.Testing position has the weeds population of self-sow.The weeds spectrum includes but not limited to black nightshade, barnyard grass grass, moleplant seed, lady's-grass, eleusine indica, clearvers, dayflower, kitchen garden, piemarker, lamb's-quarters, cyperus iria, the rhizome of nutgrass flatsedge.

The volume that applies is the 150-325L per hectare.All using all uses accurate gas manual sprayer use 2 or 3m cantilever to use flat fan nozzle to broadcast sowing inorganic agent on soil.

Estimate:

Classification is carried out to the splat of processing and the splat of contrast in various intervals after using.Classification is based on the visible weeds control of percentage (%), and wherein 0 corresponding to not injury, and 100 corresponding to killing fully.

Collect all test for data, and use the statistical method analysis.

Use the Colby formula to determine the prediction herbicidal effect of composition.

The results are summarized in the following table

Table 1 was used penoxsuam+Flumetsulam after 68 days, collaborative weeds control-

Table 2 was used penoxsuam+Flumetsulam after 68 days, collaborative weeds control-

Test 2: to the evaluation of composition activity of weeding behind bud under the condition afield

Method:

These are tested afield and carry out under the condition.Testing position is positioned at the grape garden of the commercial plantation in Kunshan.Thereby the plantation of grape is used normal conventional practice to be used to apply fertilizer, sow and is safeguarded the good growth of guaranteeing crop and weeds.This test adopts conventional research method to carry out.The splat of test is that 2 to 4.5 meters wide * 5.5 are meter to 10 meters long.All inorganic agents use all at random fully that group experimental scheme in district's applies, and wherein each inorganic agent repeats 3 or 4 times.Testing position has the weeds population of self-sow.Weeds spectrums includes but not limited to black nightshade, common lamb's-quarters, kitchen garden, climbing groundsel.
