In recent years, along with continuous and large-scale delivery of agricultural input products and rural wastes, the eutrophication degree of water bodies is increasingly serious, and duckweed and sophorae-leave apples are endangered by flooding on water surfaces of river channels, lakes, reservoirs, ponds and the like in the middle and downstream regions of Yangtze river, so that ecological balance is seriously influenced. The duckweed and the pagodatree leaf apples need to consume nutrient salts such as nitrogen, phosphorus and the like in the water body for growth, and a small amount of plants have the effect of purifying the water quality; however, the large area is overgrown, and serious pollution is caused to the water body. The major hazards of duckweed and sophorae leaf apples involve: 1) Pollution to water quality, breeding of bacteria and threat to drinking water safety; 2) Covering the channel, preventing navigation and affecting the safety of navigation; 3) The oxygen content of the water body is reduced, and aquatic organisms such as fish and shrimp are harmed, so that the healthy development of the aquaculture industry is affected; 4) Covering the water surface, shielding sunlight to cause turbidity of the water body, and carrying out chemical reaction on a large amount of organic matters to increase toxic bacteria and harm aquatic organisms, thereby seriously damaging ecological balance of the water body; 5) The ecological landscape is destroyed, and the water surface and the environment are beautified. At present, the duckweed and the pagodatree leaf apples are mainly controlled by manual salvage, the cost is high, the efficiency is low, the control effect is poor, the regeneration spreading hazard is serious, and a novel method for preventing and killing the duckweed, the pagodatree leaf apples is high in efficiency, low in cost, safe to the environment and good in economic and ecological benefits is lacked.
The chemical name of the fluoropyrimidinyl ether is O- [2, 6-bis (4, 6-dimethoxy-2-pyrimidinyl) oxy ] benzoyl benzene (2-trifluoromethyl) aldoxime, belongs to acetolactate synthase inhibitors, inhibits synthesis of acetolactate by absorption of weed stems and leaves to inhibit synthesis of branched-chain amino acid organisms, and can be used as selective herbicide for preventing and killing various grassy weeds and broadleaf weeds in paddy fields.
The chemical name of carfentrazone-ethyl is ethyl-2-chloro-3- { 2-chloro-5- [4- (difluoromethyl) -4, 5-dihydro-3-methyl-5-oxo-1H-1, 2, 4-triazol-1-yl ] -4-fluorophenyl } propanoate, belongs to triazolinones herbicide, can inhibit the activity of sensitive weed protoporphyrin oxidase, accumulate toxic intermediate five, destroy weed cell membranes and lead leaves to quick drying and death. The carfentrazone-ethyl is mainly used for preventing and killing broad-leaved weeds such as cleavers, abutilon, pigheart, shepherd's purse, sun-euphorbia herb, wheat and other cereal crop fields after seedling and stem treatment and part of annual sedge weeds, and has special effects on resisting weeds of sulfonylurea herbicides.
At present, no report on the compounding of the acifluorfen and the carfentrazone-ethyl exists, and no report on the use of the compound composition of the acifluorfen and the carfentrazone-ethyl for preventing and killing duckweed and sophorae-leave apples exists.

Test materials: duckweed (Lemna minor l.), sophorae apple (Salvinia natans (l.) all.) and salvage 6 months in 2020 from the river channel in the ginger weir area of tazhou, jiangsu province.
Test instrument: spray towers, electronic balances, volumetric flasks, triangular flasks, beakers, graduated cylinders, plastic bowls, pipettes, and the like.
The test method comprises the following steps: firstly, weighing a certain mass of primisulfuron and carfentrazone-ethyl raw medicines, and adding methanol to the raw medicines sufficientlyDiluting with 0.1% Tween 80 water solution, preparing into single-dose mother solution, setting series of ratios according to the mixing purpose, and setting 5-7 concentration gradients for use in each ratio. A plastic bowl (15 cm. Times.11 cm. Times.7 cm) was filled with water (water was collected from a pond of the academy of agricultural sciences of Jiangsu province), healthy duckweed and sophorae apple were selected, washed off dirt and impurities by tap water, and 5g (100% surface coverage) was weighed and put into the plastic bowl. Spraying, and placing into the academy of agricultural sciences of Jiangsu province for 300m 2 Culturing in a sunlight greenhouse, and supplementing water every day.
After the medicine, the growth conditions of duckweed and pagodatree leaf apples are observed regularly. Fresh weights of duckweed and sophorae apple were investigated 30 days after the drug, and fresh weight inhibition rate was calculated, i.e., the control effect on target weeds. Adopting a DPS data processing system to obtain a virulence regression equation of the single dose and the composition, and calculating ED 50 Values and 95% confidence limits. And calculating the co-toxicity coefficient by using a grand cloud Pei method. Co-toxicity coefficients greater than 120 are expressed as synergy, less than 80 are expressed as antagonism, and between 80 and 120 are expressed as additive.
Test results: 20 days after the administration, the acifluorfen and carfentrazone were observed at a ratio of 2-12: the duckweed and the pagodatree leaf apple leaves which are mixed and treated in a proportion of 0.5-15 turn yellow to dead, the inhibition effect rises with the increase of the dosage of the medicament, and the duckweed and the pagodatree leaf apple have high biological activity.
The 8 binary mixed combinations of pyribenzoxim and carfentrazone-ethyl have obvious inhibition effect on the fresh weight of duckweed 30 days after the medicine (table 1). The co-toxicity coefficient is partially between 80 and 120, and partially is more than 120, and the co-toxicity coefficient is represented by additive or synergistic effect.
