Abstract
The present invention relates to a weed killer for lawns. The present invention comprises the following components according to the parts by weight: 0.5 to 2% of sulfonmeturon methyl, 0.5 to 2% of thifensulfuron, 10 to 60% of pendimethalin, 2 to 4% of nekal, 4 to 6% of sodium lignosulfonate, 4 to 6% of sodium naphthalene sulfonate formaldehyde condensation compound and 8 to 12% of hydration silicon dioxide, and the rest is light-weight calcium carbonate. The present invention can concurrently control gramineae weeds, broadleaf weeds and partial sedge family weeds and be used for various lawns.
Description
Technical field
The invention belongs to the weed control field, particularly relate to the weed killer herbicide of a kind of lawn special use.
Background technology
Preventing and kill off at present all manually pulling out of China's turf weed, but manually pulled out more shortcoming, efficient is low, weak effect, many weeds can not be eradicated, and the growth of weeds of crawling is difficult to pull out etc., therefore needs the lawn herbicide of special-purpose highly effective and safe.Present domestic chemical control technology comparatively lacks, and its research still is in the starting stage.
Registered lawn herbicides special is of less types in medicine inspecting institute of the Ministry of Agriculture, and existing kind has " elegant hundred palaces ", " it is swelled "." elegant hundred palaces " are developed by Japanese Ishihara Sangyo Kaisha, Ltd., and its chemical name is " flazasulfuron ", and English general " flazaculfuron " by name is used for dim season such as Bermuda grass, Manila type lawn and prevents and kill off grass family, broad-leaved class and sedge weed.The limitation of this medicament is to be used for the dewdrop grass lawn, and cost is high, reaches every mu more than 80 yuan, only can bear so expensively at golf course, uses less at the conventional environment greening lawn.
" it being swelled " is The Dow Agrosciences, LLC.'s exploitation, and its chemical name is " fluroxypyr ", and English general " fluroxypyr " by name is used for Gramineae lawn and prevents and kill off broad leaved weed.Its shortcoming is to prevent and kill off grassy weed and the sedge weed in the lawn.
Summary of the invention
What the present invention will solve is that existing lawn herbicide is prevented and kill off the too single technical problem of object, provides a kind of and can doublely control grassy weed, broad leaved weed and part sedge weed, can be used for the lawn herbicide on multiple lawn.
The technical solution used in the present invention is such: lawn herbicide, mainly contain the active ingredient (weight portion) of following content: metsulfuron-methyl (metsulfuron-methyl) 0.5-2%; Thifensulfuronmethyl (thifensulfuron-methyl) 0.5-2%; Pendimethalin (pendimethalin) 10-60%.
The further technical scheme of the present invention is such: lawn herbicide, contain following composition (weight portion): metsulfuron-methyl (metsulfuron-methyl) 0.5-2%; Thifensulfuronmethyl (thifensulfuron-methyl) 0.5-2%; Pendimethalin (pendimethalin) 10-60%; Draw back powder 2-4%; Sodium lignin sulfonate 4-6%; Naphthalenesulfonic acid-formaldehyde condensate 4-6%; Hydrated SiO 2 8-12%; Precipitated calcium carbonate with surplus.
Further, the present invention can adopt following technical scheme: lawn herbicide, contain following composition (weight portion): metsulfuron-methyl (metsulfuron-methyl) 0.8-1.5%; Thifensulfuronmethyl (thifensulfuron-methyl) 1.0-1.7%; Pendimethalin (pendimethalin) 25-40%; Draw back powder 2-4%; Sodium lignin sulfonate 4-6%; Naphthalenesulfonic acid-formaldehyde condensate 4-6%; Hydrated SiO 2 8-12%; Precipitated calcium carbonate with surplus.
Best-of-breed technology scheme of the present invention is such: lawn herbicide, contain following composition (weight portion): metsulfuron-methyl (metsulfuron-methyl) 1.2%; Thifensulfuronmethyl (thifensulfuron-methyl) 1.4%; Pendimethalin (pendimethalin) 33%; Draw back powder 3%; Sodium lignin sulfonate 5%; Naphthalenesulfonic acid-formaldehyde condensate 5%; Hydrated SiO 2 10%; Precipitated calcium carbonate 41.4%.
The present invention can effectively prevent and kill off grass family and broad leaved weed in the dewdrop grass lawn with three kinds of active ingredient reasonable combination, and bermuda grass turf grassy weed and broad leaved weed are had good preventive effect.
