Test method：Weed seed is unified into vernalization, by pretreatment for examination weed seed uniform broadcasting in soil surface. In the ranks seedling, every basin final singling are each to handle 4 basins examination material to 30 plants for dispenser advance.Weeds are carried out with cauline leaf spraying treatment, investigation is dead Strain number, calculate weeds strain preventive effect (in table strain preventive effect be 4 repetitions average value), the statistical test situation after experiment 45 days, As a result such as table 1：
Preventive effect of the herbicide of the present invention of table 1 to sorghum field weed
The composition that result of the test can be seen that the present invention from table has well to sorghum field broad leaved weedses barnyard grass Preventive effect, active component polybenzobisoxazole humulone and the chlorine sodium of 2 first 4, the different monooctyl ester of the chlorine of 2 first 4, the chlorine diformazan ammonium salt of 2 first 4, the different monooctyl esters of 2,4-D, Fluroxypyr, fluorine chloropyridine ester, azoles humulone, fluoroglycofen-ethyl, halosulfuronmethyl, atrazine, metribuzin, double fluorine sulphurs grass Between amine, bentazone, Brominal, bromoxynil octanoate, mesotrione, dichloro quinolinic acid active component there is significant synergy to make With, it is particularly evident to Amaranthus retroflexus, barnyard grass synergistic effect, to sorghum safety.As cauline leaf process agent, missible oil, microemulsion, water and milk Agent, suspending agent, dispersible oil-suspending agent, wettable powder, water dispersible granules show good facility during dispenser Property, and the preventive effect of weeds is protruded, while substantially increase the security to crop.
2) demonstration test of present composition preventing and treating sorghum field weed
20 testing sites are saved within 2015 in Heilungkiang, Jilin, Liaoning, 4, the Inner Mongol and carry out exemplary popularization experiment.It is different Demonstration area sorghum variety refers to table 2.
The different demonstration area sorghum variety situations of table 2
Demonstration area Sorghum variety
Heilungkiang Dragon is miscellaneous No. 8, miscellaneous No. 10 of dragon
Jilin Ji miscellaneous 118
Liaoning Miscellaneous No. 16 of iron
The Inner Mongol Logical miscellaneous 108
Test method：After the heart of 3 leaf of sorghum 1, the weeds 3-5 leaf phases, hand sprayer, 15 kilograms/667m of the amount of being watered2, use Cauline leaf spraying even spraying, specific test medicine and dosage are shown in Table 3, and 50 square metres of plot area, often processing is repeated 4 times.Dispenser 45 days investigation preventive effects are shown in Table 3 afterwards, and sorghum safety conditions are shown in Table 4.
The field demonstration effect situation of table 3
The field demonstration sorghum safety conditions of table 4
Note：Main weeds coenotype in each demonstration pilot project：Heilungkiang：Barnyard grass+Amaranthus retroflexus；Jilin：Barnyard grass+Amaranthus retroflexus+lamb's-quarters； Liaoning：Barnyard grass+Amaranthus retroflexus；The Inner Mongol：Barnyard grass+lamb's-quarters.
By lot of experiments and exploration, it is an unexpected discovery of the invention that polybenzobisoxazole humulone is mixed with active component B, for sorghum Field after seedling prevents and kill off broad leaved weedses and barnyard grass, has surprising, unexpected synergistic effect, especially to Amaranthus retroflexus, Lamb's-quarters, barnyard grass and cruciferous weed have particularly evident synergistic effect, while can reduce dosage, improve crop safety, The pollution to environment is reduced, and rationally compounding reduces agricultural cost, has good prospect.
