[0157] Experiment on weed effect in pre-emergence stage:
[0158] The seeds of monocotyledonous and dicotyledonous weeds and main crops (wheat, corn, rice, soybean, cotton, oilseed rape, millet and sorghum) were put into a plastic pot loaded with soil and covered with 0.5-2 cm soil. The test compounds of the present invention was dissolved with acetone, then added with tween 80, diluted by a certain amount of water to reach a certain concentration, and sprayed immediately after sowing. The obtained seeds were incubated for 4 weeks in the greenhouse after spraying and the test results were observed. It was observed that the herbicide mostly had excellent effect at the application rate of 250 g a.i./ha, especially to weeds such as Echinochloa crusgalli, Digitaria sanguinalis and Abutilon theophrasti, etc. And many compounds had good selectivity for corn, wheat, rice, and soybean.
[0159] It is indicated from the experiment of main weeds in wheat and rice fields that the compound of the present invention generally have good weed control efficacy. Above all, it is noted that the compound of the invention have extremely high activity to broad-leaved weeds and cyperaceae weeds, which are resistant to ALS inhibitor, like Sagittaria trifolia, Scirpus juncoides, Cyperus difformis, Descurainia sophia, Capsella bursa-pastoris, Lithospermum arvense, Galium aparine L., and Cyperus rotundus L., etc., and have excellent commercial value.
[0160] Transplanted rice safety evaluation and weed control effect evaluation in rice field:
[0161] Rice field soil was loaded into a 1/1,000,000 ha pot. The seeds of Echinochloa crusgalli, Scirpus juncoides, and Bidens tripartita L. were sowed and gently covered with soil, then left to stand still in greenhouse in the state of 0.5-1 cm of water storage. The tuber of Sagittaria trifolia was planted in the next day or 2 days later. It was kept at 3-4 cm of water storage thereafter. The weeds were treated by dripping the WP or SC water diluents prepared according to the common preparation method of the compounds of the present invention with pipette homogeneously to achieve specified effective amount when Echinochloa crusgalli, Scirpus juncoides, and Bidens tripartita L. reached 0.5 leaf stage and Sagittaria trifolia reached the time point of primary leaf stage.
[0162] In addition, the rice field soil that loaded into the 1/1,000,000 ha pot was leveled to keep water storage at 3-4 cm depth. The 3 leaf stage rice (japonica rice) was transplanted at 3 cm of transplanting depth the next day. The compound of the present invention was treated by the same way after 5 days of transplantation.
[0163] The fertility condition of Echinochloa crusgalli, Scirpus juncoides, Bidens tripartita L. and Sagittaria trifolia 14 days after the treatment of the compound of the invention and the fertility condition of rice 21 days after the treatment of the compound of the invention respectively with the naked eye. Evaluate the weed control effect with the above activity standard level. Many compounds show excellent activity and selectivity.
[0164] Note: The seeds of Echinochloa crusgalli, Scirpus juncoides and Bidens tripartita L., and Sagittaria trifolia were collected from Heilongjiang Province of China. The tests indicated that the weeds were resistant to the common doses of Pyrazosulfuron-ethyl.
[0165] At the same time, it is found after several tests that the compounds and compositions of the present invention have good selectivity to many gramineae grasses such as zoysia japonica, bermuda grass, tall fescue, bluegrass, ryegrass and seashore paspalum etc, and are able to control many important grass weeds and broad-leaved weeds. The compounds also show excellent selectivity and commercial value in the tests on sugarcane, soybean, cotton, oil sunflower, potato, orchards and vegetables in different herbicide application methods.
