example 1

[0017] Take Chinese crabgrass, purslane, and Artemisia oleracea as test weeds, set 6 concentrations of 1000, 500, 250, 125, 62.5, and 0 mg / kg, and use methanol: acetone = 4: 1 (v / v) as the solvent to dissolve 4-Hydroxy-3-methoxycinnamic acid ethyl ester prepared to the corresponding concentration. Put a glass rod in a 50mL beaker, spread 2 layers of filter paper, wet the filter paper with 1000μL of prepared medicine, dry at 40°C for 60min, evaporate the solvent, add 1000μL sterilized distilled water to each beaker to wet the filter paper . 10 germinated weed seeds were scattered into each beaker, and each treatment was replicated three times, randomly placed in a constant temperature light incubator. Cover the beaker with a petri dish and place it in a constant temperature incubator at 25°C, with a photoperiod of 12h and a light intensity of 6000 lx. After 4 days, add 1 mL of distilled water to each beaker. After 7 days, the root length and stem length of each weed were cou...

Abstract

The invention discloses a substance ethyl 4-hydroxy-3-methoxycinnamate with herbicidal activity and belongs to the field of application of artificial synthetic chemicals to agricultural plant protection. The substance has a certain inhibitory effect on weeds such as digitaria sanguinalis, amaranthus retroflexus, barnyard grass, Setaria viridis, Chloris virgata, etc., and has the best inhibitory effect on the weed digitaria sanguinalis. IC50 is 281.53 mg.L<-1>. The substance is safe and environment-friendly, and is harmless to non-target crops.

Description

technical field [0001] The invention discloses a synthetic method for artificially synthesizing ethyl 4-hydroxy-3-methoxycinnamate and a method for preventing and controlling agricultural weeds, belonging to the field of artificially synthesized chemicals applied to agricultural plant protection. Background technique [0002] There are more than 30,000 species of weeds in the world, of which more than 1,800 species can cause damage to various agricultural crops, causing a loss of about 9.7% of the total crop output every year. Conventional chemical herbicides are commonly used to control weeds at present, but their disadvantages are becoming more and more prominent after long-term use, such as resistance of weeds, pollution of water and soil, and difficult degradation of residues. It has become a top priority to develop new herbicides that are pollution-free and safe. Biogenic herbicides are favored by people because of their small impact on non-target plants, small environ...
