[Summary of the Invention]

However, there are cases in which the use of the respective active ingredients alone may leave uncontrollable weeds, and many cases in which the residual grass treatment must be treated again. Even if multiple herbicides are used together, it is still difficult to control a variety of weeds. Therefore, it is expected to create a herbicide composition which is highly safe for cultivated plants and can effectively control more kinds of weeds and the like with a lower dose. In grasses and broadleaf weeds, there are many cases where the susceptibility to herbicides is very different. In the case of crop-selective herbicides, it is especially difficult to control these weeds at the same time. Further, various weeds which are resistant to herbicides have also become problems in recent years, and herbicide compositions and weed control methods which can simultaneously control such herbicide-resistant weeds are being sought.

The evaluation of the mixed use of ethylpyrrolidin and acetochlor or/and grass was carried out by mixing commercially available acetochlor and grasses with a single dose of ethylpyrrolid.

Test Example 1. Pre-emergence treatment of pots of Goosegrass and Cynodon dactylon

The resin-made pots with an area of 63.5 cm ² were filled with alluvial sandy loam, and the seeds of the tendon grass and the Bermudagrass were uniformly sown on the surface, and the soil was uniformly covered. On the next day of sowing, each herbicide was diluted to the specified concentration or diluted and mixed with the soil. A single agent of each active ingredient is a commercially available agent or a preparation according to the formulation. Further, they are mixed to prepare a mixed treatment liquid.

After the herbicide treatment, the pots were placed outside the house to continue the plant cultivation management for 22 days. Thereafter, the herbicidal effect was evaluated, and the expected value was calculated according to Equation 1. The results are shown in Table 1. The DAA in the table indicates the number of days after processing. (The same table below.)

Test Example 2. Dryland soil treatment test for Goosegrass and Aconite

The weeding effect test was carried out in the dryland field where the tendon grass and the fragrant aconite were uniformly distributed in the area. The seeds of corn are uniformly sown and uniformly covered. Thereafter, each herbicide is diluted to the specified concentration on the next day of sowing. Or diluted ‧ the mixture is uniformly distributed to the soil. After 30 days of treatment, the herbicidal effect (growth inhibition rate) of the goosegrass and the fragrant aconite that naturally occurred in the market was visually evaluated, showing 0% (no herbicidal effect) to 100% (completely inhibited grass).

Based on the herbicidal effect (inhibition rate) (%) after 30 days of the drug treatment (30 DAA), the expected value (E1 in the table) was calculated according to the formula 1. The results are shown in Table 2.

As can be seen from Table 2, in the case of single treatment with ethylphenfenazone or acetochlor, the effect of the supply test did not show sufficient effect on the weeds and sedge weeds, but by The combination of chlorfenapyr and acetochlor was observed, and the multiplication effect of the expected value (E1) was observed, showing excellent herbicidal effect. Also, no phytotoxicity was observed in the various areas of corn. Similarly, in the case where the drug treatment was carried out 2 days after the sowing, excellent herbicidal effects were observed, and no phytotoxicity to corn was observed.

As the post-emergence treatment, the same herbicidal effect can be expected even if the same chemical treatment is carried out in the 2 leaf stage or the 3 leaf stage of corn. However, depending on the occasion, there is a possibility of causing mild phytotoxicity.

Test Example 3. Dryland soil treatment test for broadleaf weeds

In the same manner as in Test Example 2, the herbicidal effect test was carried out in the open field where the morning glory and the cucurbitaceae genus weeds naturally occur. The results are shown in Table 3.

As can be seen from Table 3, in the case of treatment with ethylphenfenacil or acetochlor or a single herbicide, the effect of the test on the dose did not show sufficient effect on the morning glory and the genus However, by dissociating ethylphenfentoside with acetochlor or ethylphenanthrene and grass, the synergistic effect of the expected value (E1) was observed, and an excellent herbicidal effect was exhibited. Also, no phytotoxicity to corn was seen in each district. Similarly, in the case where the drug treatment was carried out 2 days after the sowing, an excellent herbicidal effect was observed, and no phytotoxicity was observed on the corn.

Test Example 4. Dry soil treatment test of Goosegrass and Aconite

In the same manner as in Test Example 2, the herbicidal effect test of three kinds of mixtures was carried out in the natural occurrence of the goosegrass and the fragrant aconite. The herbicidal effect (inhibition rate) (%) after 30 days from the treatment of the drug was calculated according to the formula 2 (in the table, E2). The results are shown in Table 4.

As can be seen from Table 4, in the case where ethylfenfen, acetochlor, or grass was treated as a single agent, the amount of the drug supplied to the test did not show sufficient effects on the weeds and sedge weeds. However, by treating three kinds of ethylphenanthrene with acetochlor and grass, the synergistic effect of the expected value (E2) was greatly improved, and an excellent herbicidal effect was observed. Also, no phytotoxicity to corn was seen in the districts. Similarly, in the case of drug treatment after 2 days of sowing, it was considered that there was an excellent herbicidal effect, and no phytotoxicity was observed for corn.

Test Example 5. Dryland soil treatment test for broadleaf weeds

In the same manner as in Test Examples 2 and 4, the weeding effect test of the three kinds of the mixture was carried out in the open field where the morning glory and the genus Hemerocallis were naturally occurring. The results are shown in Table 5.

As is clear from Table 5, in the case of treatment with ethylphenfenazone, acetochlor, or a single herbicide, the amount of the drug supplied to the test did not show sufficient for the morning glory and the yarrow weeds. The effect was obtained by treating three kinds of ethylphenanthrene with acetochlor and grass, and observing the effect of greatly increasing the expected value (E2), and showing an excellent herbicidal effect. Also, no phytotoxicity to corn was seen in the districts. Similarly, in the case of the treatment of the drug after 2 days of sowing, excellent herbicidal effects were also observed, and no phytotoxicity to corn was observed.

Others, by the same test, the multiplication effects of Chloris weeds, Amaranthus weeds, and Compositae weeds were also observed.

Test Example 6. Dry soil treatment test of Italian ryegrass and bluegrass

The resin-made pots with an area of 63.5 cm ^{2 were} filled with alluvial sandy loam, and the seeds of the ryegrass and bluegrass were uniformly sown, and the soil was uniformly covered. On the next day of sowing, each herbicide was diluted to the specified concentration or diluted. The mixture was uniformly distributed to the soil. A single agent of each active ingredient is a commercially available agent or a preparation according to the formulation. Further, these were mixed to prepare a mixed treatment liquid.

The pots treated with the herbicide were placed outside the house and cultivated 31 days after the treatment. Thereafter, the herbicidal effect was evaluated, and the expected value was calculated according to Equation 1. The results are shown in Table 6. The DAA in the table indicates the number of days after processing.

[Table 6] The herbicidal effect of pre-emergence treatment on ryegrass and bluegrass

It can be seen from Table 6 that in the case where ethylfenfen, acetochlor, or grass was treated as a single agent, the amount of the drug supplied to the test did not show sufficient effects on the ryegrass and bluegrass, but When the ethylphenanthrene and the acetochlor and the grass were removed and treated in three ways, the synergistic effect of the expected value (E2) was greatly improved, and the excellent herbicidal effect was exhibited.

Further, it is considered that the effect of multiplying the ethylphenfenate only with acetochlor or only with the grass and treating it.
