Description
Technical Field

Background
Corn is one of main grain crops planted in China, the seeding area of the corn in 2019 nationwide reaches 4153 ten thousand hectares, the corn is mainly distributed in northeast and north China, and the total yield reaches 2.554 hundred million tons. At present, the demand of the domestic corn market is continuously increased, and the demand of continuously improving the corn yield is required. The water and fertilizer competition between the field weeds and the corns is one of the main factors influencing the corn yield, and if the weeds and the corns are not controlled, the yield of the corns is greatly reduced. The main weeds harmful to corn field include barnyard grass, crab grass, green bristlegrass herb, teff, purslane, Li, broomcorn millet, xanthium sibiricum, black nightshade herb, goosegrass herb, amaranthus retroflexus, polygonum, acalypha australis, cyperus rotundus, black nightshade herb, etc. The harm is the largest in the seedling stage, the corn yield can be seriously influenced by short and small corn plants, yellow stems and leaves and the like, and the yield reduction amplitude can reach about 35 percent.
Farmland weeds are a large biological disaster seriously threatening crop production, and have serious influence on crop yield and agricultural production. Currently, pesticide application is the most effective means for controlling weeds in the field. However, the pesticide with a single active component is continuously used for a long time at a high dosage, so that the pesticide resistance of weeds to the pesticide is gradually enhanced, the problem that different types of weeds are mixed in the same crop often exists, different pesticide varieties are required to be respectively adopted for preventing and treating the weeds with different types, the prevention and treatment period is long, the effect is poor, the cost is high, and serious environmental pollution is caused. Therefore, there is an urgent need to develop a pesticidal composition that can effectively cope with the mixed occurrence of different types of weeds and can effectively increase the crop yield.
With the increase of the service life of the herbicide in the corn field, the resistance of weeds to the existing herbicide is increased, and the types and the quantity of weed which is difficult to prevent and remove in the corn field are increased. Therefore, the development of a novel corn field herbicide with high efficiency, low toxicity and low residue is urgently needed.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Test example 1
Test site: south ning city of Guangxi province. The land has flat land and good fertility. And (4) managing the corns in each treatment area after the application according to the conventional production.
Specific examples will be listed below to representatively illustrate embodiments of the present invention.
The composition takes the metolachlor as an active ingredient (A), the topramezone as an active ingredient (B) and the optional terbuthylazine as an active ingredient (C), and has obvious synergistic effect on the prevention and control of weeds in corn fields by single-component binary or ternary compounding.
Indoor toxicity test
The determination method comprises the following steps:
sowing the germinated dry seeds of large crabgrass, barnyard grass, Li and eyebrow pennyroyal uniformly in black plastic nutrition cups (diameter 40cm) filled with nutrition soil, covering soil with 60 granules per cup, soaking in water to completely wet the soil, and culturing in a greenhouse. And when the weeds grow to 4-6 leaves, determining 20 plants per cup for later use.
The medicament is completely dissolved by acetone to prepare mother liquor, and the mother liquor is gradually diluted to the required concentration according to the requirement of experimental design dosage.
Spraying stem leaves; the spray tower is used for spray treatment of stem and leaf, and has water content of 100mL/m2, droplet diameter of 100 μm, and nozzle flow rate of 90 mL/min-1And a clear water contrast is set.
The combination action types of the 3 herbicides are evaluated by a Colby method, and the actual control effect of the mixed herbicide is calculated by the following formula:
E0＝X*Y*Z/100(n-1)
x is the survival rate of the weed of the herbicide A when the dosage is P;
y is the survival rate of the weed of the herbicide B when the dosage is Q;
z is the survival rate of the weed of the herbicide C when the dosage is W;
n is the number of the mixed medicaments, namely n is 3;
e0 is the theoretical weed survival rate of the herbicide (A + B + C) at the dosage of (P + Q + W);
e is the actual weed survival rate of the herbicide (A + B + C) at the dosage of (P + Q + W);
E0-E is more than 10% of synergistic effect; E0-E < -10% is antagonistic; an E0-E value between. + -. 10% is additive effect.
Measuring the fresh weight of the overground part, and respectively counting the fresh weight control effect:
fresh weight control (%) (fresh weight of placebo weed-fresh weight of agent treated weed)/fresh weight of placebo weed 100; the survival rate (%) of the weeds is 100-fresh weight control effect.
TABLE 1 fresh weight control of individual agents on large crabgrass, barnyard grass, Li and teff
TABLE 2 evaluation of the control of ternary built reagents in different proportions
As can be seen from the data in the tables 1 and 2, the fresh weight control effect of the compound of the metolachlor, the topramezone and the terbuthylazine on large crabgrass, barnyard grass, Li and teff is far greater than that of each single agent, and the E0-E is more than 10% under a series of mixture ratios, so that the compound of the metolachlor, the topramezone and the terbuthylazine has obvious synergistic effect.
Test example 2
The liquid medicines in examples 2, 9-12 and comparative examples 1-6 were uniformly sprayed on the corn fields in each planting area before sowing seedlings, respectively, by using a knapsack sprayer according to the application amount of 100 g/mu, and a clear water control was set. The planting conditions were identical for each planting area except that the herbicide was applied according to the above-described protocol. And (3) identifying and counting weeds in the planting area 40 days after the herbicide is sprayed, and calculating the plant control effect according to the following formula:
the plant control effect is (the number of the weed plants in the blank processing planting area-the number of the weed plants in the herbicide processing planting area)/the number of the weed plants in the blank processing planting area is 100 percent;
and statistics were made on the corn yield in the growing area, the results are shown in table 3.
TABLE 3
As can be seen from the data in Table 3, compared with the single-component s-metolachlor, topramezone or terbuthylazine, or the binary combination of s-metolachlor, topramezone and terbuthylazine, or the herbicide combination of other components, the ternary combination composition has good control effect and synergistic effect, and can control various non-cultivated land weeds, reduce the application times, save the cost and reduce the pollution to the environment. When the herbicide composition is a microcapsule suspension-suspension agent, better control effect can be obtained compared with other formulations.
