The biological test example is to the control test of corn weeds in field
Test method:
Between corn field there be the main weeds that occur: the lady's-grass grass, the barnyard grass grass, green foxtail, piemarker, chickweed, the thorn amaranth, Siberian cocklebur, leaf mustard, Amaranthus retroflexus, recessed amaranth, field thistle, setose thistle, bur beggar-ticks, beggar-ticks, pale persicaria, willow spurt knotweed, kitchen garden, flowerofanhour root or herb, clearvers, sunflower, smallflower galinsoga herb, corn radish, salsola collina, the thorn bur, corn sow thistle, chickweed, datura, lamb's-quarters, little lamb's-quarters, black nightshade, dayflower, artemisiifolia, big dish, penny cress, leaf mustard, wild mustard and other japanese bearbinds belong to, Chenopodium, Polygonum, artemisia, rape belongs to weeds, lamb's-quarters, amaranth, clearvers, knotweed, german chamomile, saltbush, datura, chickweed, summer cypress, piemarker and black nightshade etc.
We just select several difficult cutting weeds as subjects in the test below.
Medicament adopts now with the current mode, and we test with the prescription of embodiment the inside.Potted plant cultivation is adopted in the cultivation of target weeds, uses the 10*10cm plastic basin, will not use soil in the corn field of weed killer herbicide as cultivating soil.Barnyard grass grass, eleusine indica, lamb's-quarters, the Amaranthus retroflexus seed gathered between corn field last one year are sprinkling upon soil surface, wait it to grow 2 ~ 4 leaves.Spray mesotrione then successively, butachlor, Bentazon is according to the medicament of the present invention's preparation.Carry out observation analysis then.After the medication weeds are carried out normal management, and in medication 48 hours, note rainproof.Observe the growing state of weeds behind the medicine, each processing of record weed killer herbicide is to the preventive effect of weeds.Behind the weeds medicine 30 days, each handled fresh weight preventive effect to weeds investigation.
Fresh weight preventive effect (%)=[check plot weeds fresh weight-treatment region weeds fresh weight]/[check plot weeds fresh weight] * 100
Dispenser is the investigation of weeds fresh weight preventive effect after 30 days
Table 1
Conclusion: as can be seen from Table 1, dispenser is after 30 days, and according to ternary recompounded composite of the present invention, to barnyard grass grass, eleusine indica, lamb's-quarters, the preventive effect of Amaranthus retroflexus apparently higher than the preventive effect of single agent, has obvious gain effect all more than 80%.And according to composition of the present invention, the amount of application of active ingredient obviously reduces than single agent amount of application.
