DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite herbicide for paddy fields and a weeding method, and in particular, it has a wide spectrum of grasses including both common paddy weeds and perennial paddy weeds, and has an excellent effect against paddy weeds. Despite showing a weed effect, the chemical damage to paddy rice originally caused by one of the components of the compound herbicide is significantly reduced. 1 is applied to paddy field #1 before germination or in the early stages of growth after germination, including perennial paddy weeds for which it has been difficult to achieve the conventional herbicidal effect, and - flat paddy weeds and perennial paddy weeds. This is a unique herbicide for Japonica rice that exhibits a remarkable weeding effect on weeds that contain both types of water, and does not cause any practical damage to rice in Japonica rows. Regarding the method gradually.

For example, as shown in Table 3 later, in a field test under natural conditions, 75?
Even in the case of fishing use, the compound of formula (1) is somewhat unsatisfactory against Japanese millet (Ec), but it is effective against other flat-grown paddy weeds and perennial waterweeds in the wide C2 range. However, when applied to Japonica seed water (18 "Nihonpare"), the compound of formula (2) was used in the same application, although it produced a herbicidal herbicidal activity that could not be used in practical use. Just by adding X11 to the history, it maintains its excellent herbicidal activity by substantially V
(Sao L), a completely unexpected and remarkable selective chemical damage reduction in which only the chemical damage to the glossy water T1i was reduced to the point where it could be ignored in practical terms. It can be seen that 5 things are done.

After that, water can be applied to flooded paddy fields for about 1 to about 15 days, preferably about 2 to about 14 days, to achieve particularly effective weeding and selective weeding. It is ingenious because it shows the effect of reducing chemical damage and can be seen as a sign of Buddhism for paddy rice. During the above period, the area of rice cultivation, japonica seeds, and quality of rice! ,
Depending on the nature of paddy field weeds, growth conditions, weather, and winter crops that change over time, it is possible to select a trunk, and it can be slightly phased or extended, but spreading immediately before or after transplanting may damage young paddy rice plants. It is particularly preferable to apply it at the upper (self-loving stage... 1) because the herbicidal effect on water H4 ha1 grass will be reduced if the blood pressure exceeds 8.

Furthermore, upon application, the inventive japonica seed rice 4V cultivation @4 agent is superior to conventional paddy herbicides with a significantly reduced application rate compared to known herbicides for rice cultivation. In addition to showing a targeted extermination effect, it also shows excellent results in that it acts effectively against common weeds and perennial weeds with a wide spectrum of complaints, and exhibits a selective chemical damage reduction effect.
