Perennial weed control agent for grassland grassland and method for controlling weeds perennial weeds in grassland

The present invention relates to a grassy perennial weed control agent for grassland with high herbicidal effect on grasses perennial weeds and high medicinal damage even if used alone, and grassland grasses perennial weeds The prevention method.

This case claims priority based on Japanese Patent Application No. 2012-008663 filed on January 19, 2012 in Japan, and its contents are hereby incorporated.

Grassland is used for golf courses, parks, courtyards of general families, riverbanks, and undergrowth of orchards to maintain aesthetics, disaster prevention, and provide entertainment venues.

The control of weeds becomes a problem in the process of maintaining a beautiful appearance and making grass grass grow healthily. The weeds that are bred on the grass become the cause of inhibiting the growth of grassland, and the seeds will adhere to the clothes or become a hotbed of disease pests.

Herbicides are used to control weeds that are propagated on the grass. However, the previous herbicides have a narrow spectrum of herbicides, insufficient control effects, or limited treatment methods, and various problems such as narrow processing period or environmental safety. Further, the production of resistant weeds can be seen by using the same herbicide.

For the prevention of perennial weeds of grasses such as gar or white stalks that are easily produced on grassland, Trifloxysulfuron sodium salt is considered to be effective (Patent Document 1). But in fact it lacks effectiveness. The perennial weeds of the grasses are classified and ecologically close to the grassland. Therefore, it is difficult to control the perennial weeds of the grasses, especially the white stalks, by using the existing herbicides alone. Has the type of underground stems. As a method for solving this problem, a method of using a plurality of existing herbicides or plant growth regulators (Patent Documents 1, 2, and 3) has been proposed, but there are problems such as phytotoxicity or lack of effects on some weed species, and may not be obtained. Satisfactory effect.

In the case of Patent Document 4 and the like, it is disclosed that the 1,5-diphenyl-1H-1,2,4-triazole-3-carboxylic acid decylamine derivative has herbicidal activity. Flupoxam is known to be harmless to grasses such as wild yew or manila medicinal grass, and it shows high control against annual weeds such as broad-leaved weeds such as stalks and grasses on the grass. Activity (refer to Non-Patent Document 1). Further, it is known that fluconazole exhibits high control activity against broad-leaved weeds such as sage, plantain, and sorrel which are produced on grass (refer to Patent Document 5). However, it is unknown that fluconazole has excellent herbicidal activity against grassy perennial weeds produced on grassland.

[Examples]

Hereinafter, the present invention will be specifically described by way of examples. However, the following examples are not intended to limit the scope of the invention.

(Example 1) Manufacture of particle hydrating agent

50.6 parts by mass of 1-[4-chloro-3-[(2,2,3,3,3-pentafluoropropoxy)methyl]phenyl]-5-phenyl-1H-1,2, 4-triazole-3-carboxyguanamine, 12.0 parts by mass of an anionic surfactant, 10.0 parts by mass of potassium chloride, and 27.4 parts by mass of a mineral carrier are mixed, and the mixture obtained by pulverizing with a hammer mill is used. 45 parts by mass of water was added to the mixture for kneading, and extrusion granulation was carried out using a 0.7 mm sieve, and dried to obtain a granule hydrating agent. The obtained particulate hydrating agent was used as the drug A.

As a control agent, the following commercially available preparations were used.

Agent B: Pendimethalin 45% suspension preparation (trade name: Wayup, manufactured by BASF)

Agent C: a 40.7% suspension preparation of prodiamine (trade name: Barricade, manufactured by Syngenta) and a trifluorosulfuron sodium salt 75% granule hydrating agent (trade name: Monument, Syngenta company) diluted with water to a specific concentration and mixed

Agent D: 45% of Pendimethalin's suspension preparation (trade name: Wayup, manufactured by BASF) and Cyclosulfamuron 66% of granule hydrating agent (trade name: Doubleup, manufactured by BASF) were diluted with water, respectively. To a specific concentration and mixed

Next, a test example regarding the effect of the controlling agent of the present invention is disclosed.

(Test Example 1)

Six tuber (Imperata cylindrica) tubers (about 10 cm in length) were transplanted in a pot with a depth of 5 cm. On the same day, the drugs A and B diluted with water to a specific concentration were dispersed on the soil surface at a water content of 200 ml/m ² . It was grown in a greenhouse, and after 56 days of transplantation and dispersion, the shoots were recovered and the raw weight was measured. Three tests were carried out continuously to obtain an average value. The test results are shown in Table 1. The agent A can effectively inhibit the growth of the white stalk.

(Test Example 2) Control effect of hairy gar

Six tubers of Paspalum dilatatum (3 to 5 cm in length) were transplanted in a pot with a depth of 5 cm. After 3 days, the agents A and B diluted with water to a specific concentration were dispersed on the soil surface at a volume of 200 ml/m ² . It was allowed to grow in a greenhouse, and after 56 days from the spread, the shoots were recovered and the raw weight was measured. Three tests were carried out continuously to obtain an average value. The test results are shown in Table 2. The agent A can effectively inhibit the growth of the bristles.

(Test Example 3)

Two blocks of 100 m ² were drawn from the growth area of the white stalk in the expressway of the expressway, and the dispersion liquid was prepared by diluting the agent A with tap water.

The dispersion liquid, the chemicals C and D were separately dispensed with a sprayer at a water amount of 200 ml/m ² to carry out stem and leaf treatment.

After 2 months and 3 months from the spread, the investigation was carried out, and the degree of suppression was visually confirmed and the average of the two blocks was obtained. The test results are shown in Table 3. Utilizing A (fluramine) (Flupoxam) 50.6 mass% of the particulate hydrating agent) inhibits the inhibitory effect of the agents C and D without affecting the grass grass.

Further, the suppression effect (%) is obtained by macroscopic investigation on a scale of 0% to 100% in comparison with the untreated area. 0% means that it is exactly the same as the untreated area, and the white stalk grows lush, and 100% means that the white stalk is completely dead.

(Test Example 4) Control effect of gar

A block of 5000 m ^{2 was} drawn from the growth of the gargle in the golf driving range, and the dispersion liquid was prepared by diluting the agent A with tap water.

The stem and leaf treatment was carried out by dispersing the dispersion liquid with a sprayer at a water amount of 200 ml/m ² .

After 2 months and 4 months after the spread, the investigation was conducted, and the degree of inhibition was visually confirmed. The test results are shown in Table 4. It is possible to use the agent A (50.6% by mass of the flucarbazole granule hydrating agent) to inhibit the gar on the grass for a long time without affecting the grass. Further, the suppression effect (%) is obtained by macroscopic investigation on a scale of 0% to 100% in comparison with the untreated area. 0% means that it is exactly the same as the untreated area, the gar is growing lush, and 100% means that the gar is completely dead.
