JPH0387119A - Method for preventing invasion of bad weed into green of golf course - Google Patents

Abstract

PURPOSE:To efficiently prevent the invasion of bad weeds without a herbicide by disposing weed-inhibiting zone on the whose periphery of a green in a golf course and on an approach area to the green, the weed-inhibiting zone being used for brushing off the seeds of the bad weeds adhered to the shoe bottoms of a player. CONSTITUTION:One kind or mixture of rye grass, blue grass and fescue competitively living against photo-germinating bad weeds such as Gramineae poe are cultivated on the whole periphery of a bent green-planted green in a golf course and on an approach area to the green to form a weed-inhibiting zone. The seeds of the Gramineae poa adhered to the shoe bottom of a player are brushed off with the weed-inhibiting zone comprising rye grass, etc., having a large growing rate and the germination of the seeds is inhibited under the sun shadow condition.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for preventing the invasion of harmful weeds, typified by Psyllium japonica, from entering golf course greens.

[Prior Art and Problems to be Solved by the Invention] In general, the most harmful weed that occurs in cold-season turfgrasses such as bentgrass planted on golf course greens is the staghorn grass.

Under Japan's climate conditions, Sparrow fern is a grass species that is sensitive to high temperatures to the extent that it dies during high summer temperatures, and after it naturally dies in the summer, greens become noticeably bare and impede golf play. , Preventing the invasion of greens by the Sparrow grass has become an urgent issue for those involved in golf.

However, when herbicides are used to remove Sparrowgrass that has grown in cold-season grasses such as bentgrass, cold-season grasses generally have relatively low resistance to various herbicides. This causes the inconvenience of causing the turfgrass itself to wither and die. Furthermore, the use of herbicides should be avoided as much as possible since it causes the problem of pesticide pollution.

Therefore, conventionally, there is no other suitable method for removing Psyllium spp. that has grown on cold-season grasses such as bentgrass than to manually remove it, and it is difficult to remove it from grasses that require large areas such as golf courses. It cost a huge amount of money and required a tremendous amount of effort. Furthermore, if even just a few percent of the grass grows on the green, it becomes difficult to remove the weeds by hand, and eventually the entire lawn will have to be replaced.

By the way, the main reason why Sparrow fern invades the green is because players climb onto the green with Sparrow fern seeds attached to the soles of their shoes.

In recent years, based on the above-mentioned circumstances, there has been a demand for a method for reliably removing Sparrowgrass that has grown on cold-season turf grasses such as bentgrass while avoiding herbicide damage as much as possible. This was done in response to a request.

[Means to solve the problem]

The above-mentioned problem is solved by the present invention, which is characterized by providing a deterrent zone around the entire circumference of the golf course green and at the approach to the green to shake off seeds of defective weeds adhering to the soles of shoes. This can be solved by prevention methods.

More specifically, the prevention zone provided around the entire circumference of the golf course green planted with bentgrass and along the approach to the green is planted with any one of ryegrass, bluegrass, and fescue that compete with poor photo-germinating weeds such as sycamore spp. This problem can be solved by a method for preventing the invasion of unwanted weeds onto golf course greens, which is characterized by planting a mixture of these species.

[Function] By providing a prevention zone around the entire circumference of the golf course green and on the approach to the green, the prevention zone can be used to shake off the seeds of defective weeds that have adhered to the soles of the players' shoes. It is possible to prevent Sparrow fern from entering the green.

As a specific means for constructing the blocking zone, it is possible to provide a rug or the like all around the golf course green and on the approach to the green, but this requires a large amount of rugs or the like.

In the present invention, the entire circumference of the golf course green and the approach to the green made by planting bentgrass are planted with ryegrass, bluegrass, and huscus, which compete with poor photo-germinating weeds such as sycamore, or any of these. An inhibition zone is formed by sowing a mixture of seeds, and when the player passes through this inhibition zone, a shade condition is created for the seeds of the sycamore that are blown off the soles of the player's shoes, or for the sycamore that has already germinated. As a result, the germination and growth of the sycamore can be inhibited, and the growth of the sycamore can be suppressed due to the allelobic effect of keeping other plants away from the competitive plants.

[Example] As an example of the present invention, a prevention zone is formed around the entire circumference of the golf course green and on the approach to the green using a suitable rug, etc., and when the player passes through this prevention zone, the player is blocked by the prevention zone. Make sure to brush off the seeds of the sycamore that adhere to the soles of your shoes. When the deterrent zone is constructed of a rug in this way, the seeds of Psyllium annuus blown onto the rug can be removed by washing off the rug or sucking it up with a suitable suction means.

In addition, when the entire circumference of a golf course green and the approach to the green created by planting cold-season turfgrass are formed with a deterrent zone made of turfgrass, the entire circumference of the golf course green and a specific area of the approach to the green are blocked. A zone is defined, and in this inhibition zone, any of ryegrass, bluegrass, and fescue, which grow competitively with poor photogermination weeds such as sycamore, or a mixture thereof is planted. The seeds of Psyllium annuus adhering to the soles of the players' shoes are brushed off by this deterrent zone made of ryegrass or the like. Ryegrass, bluegrass, and fescue grow faster and are more upright than sycamore, so the seeds of sycamore that are blown off into the above-mentioned inhibition zone are either ryegrass, bluegrass, or fescue, or Germination is suppressed by placing the mixed seeds in shady conditions,
Growth is inhibited.

In addition, if cold-season grass such as bentgrass all around the green and on the approach to the green is identified as a deterrent zone,
First, the bent grass in this inhibition zone is cut low using a regular lawn mower. If sycamores are already breeding in the bentgrass, cut the sycamores together with the bentgrass to a uniformly low level. Next, a top layer to promote seed establishment is applied to the low-cut lawn, and
Ryegrass, bluegrass, fescue,
Or sow a mixture of these seeds. By doing this,
Any of the above ryegrass, bluegrass, fescue, or a mixture thereof can be successfully germinated and grown in low-pruned bentgrass, creating shady conditions for the sycamore, and promoting germination and growth of the sycamore. can be prevented.

The inhibition zone of the present invention has an environment in which it is easy to germinate because a large number of seeds of Psyllium japonica have been dropped as described above, but germination can be prevented by spraying a herbicide targeting only this inhibition zone. If the foliage is treated after germination, the amount of herbicide used can be reduced as much as possible and the problem of chemical damage can be eliminated.

〔Effect of the invention〕

As explained above, according to the method of the present invention, it is possible to efficiently prevent the invasion of harmful weeds onto golf course greens by not using herbicides at all or by using only a small amount of herbicides.

Therefore, it is possible to manage weeds on a vast lawn of a golf course at low cost, for example, without resorting to conventional hand-weeding work.
