The preventing iron test of biological test example to corn weeds in field
Test method:
Between corn field, the main weeds that occur have: eleusine indica, lady's-grass grass, barnyard grass, green foxtail, piemarker, chickweed, 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, 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.
In test, we just select several more difficult cutting weeds as subjects below.
Medicament adopts now with the current mode, and we test with the formula of embodiment the inside.The cultivation of target weeds adopts potted plant cultivation, uses 10*10cm plastic basin, will not use soil in the corn field of weed killer herbicide as culture soil.The barnyard grass gathering between corn field upper one year, eleusine indica, lamb's-quarters, Amaranthus retroflexus seed are sprinkling upon to soil surface, wait it to grow 2 ~ 4 leaves.Then spray successively mesotrione, butachlor, flupoxam, according to the medicament of the present invention's preparation.Then carry out observation analysis.After medication, weeds are carried out to normal management, and in medication, note in 48 hours rainproof.The growing state of observation post administration weeds, each processes the preventive effect to weeds to record weed killer herbicide.After weeds medicine 30 days, each processed the 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, eleusine indica, lamb's-quarters, the preventive effect of Amaranthus retroflexus, all more than 80%, apparently higher than the preventive effect of single dose, has obvious gain effect.And according to composition of the present invention, the amount of application of active ingredient obviously reduces than single dose amount of application.
Synergistic herbicidal agents provided by the invention is the ternary built of butachlor, mesotrione and flupoxam, can be applied to corn field as closed soil treatment agent and seedling after cauline leaf inorganic agent, can effectively control 1 year grass family of corn field and broad leaved weed, it is desirable corn field herbicide, can effectively control the generation of resistant weed, can reduce whole use cost, and expand herbicide spectrum, and then serve better agricultural production simultaneously.
