In other words, when treated on the soil surface before weeds emerge in fields, soybeans, beets, radish,
Causes chemical damage to field crops such as wheat and corn
It is possible to effectively control weeds such as crabgrass, whiteweed, dogweed, and Japanese knotweed without having to worry about it.
(see publication). However, if Compound A is applied during the weed growth period, the control effect will be poor on the above-mentioned weeds as well as on perennial weeds such as grasshopper and commonweed.

欠点を有している。In addition, Compound B, Compound C, and Compound Ri, which are one of the active ingredients, are listed in the "Pesticide Handbook 1985 Edition" (
Japan Plant Protection Association, published on January 30, 1986), pages 356 to 360, "Short Review of Barbicide", pages 68 to 71, and pages 78 to 79. It is a known herbicide. These herbicides are used as field herbicides for wheat, potatoes, beans, carrots, etc., mainly by soil treatment before weeds emerge. Its herbicidal effect is effectively exerted when it is treated before and during the early stage of the emergence of annual grass weeds such as crabgrass, barnyard grass, foxtail grass, and staghorn grass, as well as annual broad-leaved weeds such as staghorn weed, whiteweed, Japanese knotweed, and Japanese knotweed. However, when we treat the above-mentioned weeds with advanced growth, the herbicidal effect is insufficient, and it is also not effective against weeds of the Cyperaceae family such as Cyperus japonica and Cyperus spp. Inferior. Furthermore, if Compound B, Compound C1, or Compound Ri is treated during the growing season of crops, there is a risk of causing chemical damage to crops such as soybeans and cotton, so it has the disadvantage that it cannot be used.

念される。On the other hand, weeds in fields where field crops are cultivated come in many varieties and appear at different times, making it difficult to weed them. The main weeds in the fields where the typical crops, legumes such as soybeans and adzuki beans, and cotton are cultivated, as well as the usage status of the main herbicides used to kill these weeds, are as follows. In other words, the main weeds in the cultivated areas of legumes such as soybeans and adzuki beans, and cotton include grass weeds such as cornweed, foxtail grass, silverwort, goldenberry, grasshopper, seiban sorghum, sorghum, and seaweed; There are broad-leaved weeds such as Hiroha Convolvulus, Ichi, Ebisugususa, Wildflowers, Japanese Polygonum, Purslane, Shiroza, Broomweed, Golden Grass, Blue-winged Convolvulus, Sennari Borizons, and Mulva Morning Glory. Herbicides for legumes to kill these weeds include alachlor, dinozeb, dinozeb acetate, and metribuzin during and after sowing, and pentacin, metribuzin during the growing season.
Alloxydim, setoxydim, etc. are used. In addition, as line herbicides, dinitroaniline herbicides such as trifluralin are used before sowing, and glyphosate, setoxydim, promethrin, etc. are used during the growing season. These herbicides are used effectively by taking advantage of their respective action characteristics. It is difficult to control all weeds with one drug. Furthermore, there are few herbicides that can effectively control various weeds even when used before or after the weeds emerge, and there is always concern that herbicides used during the growing season may cause chemical damage to crops.

Furthermore, no herbicide for field cultivation is known that uses a combination of Compound A and Compound B, Compound C, or Compound Ri.

ら望ましくない。Problems to be Solved by the Invention Among field crops, beans are spot-sown, so weeding along the ridges and between the plants is essential. In particular, the initial growth of adzuki beans is slow;
Weeding is essential because when weeds grow, they inhibit the growth of adzuki beans, resulting in a clear decrease in yield. However, the use of dinozeb, dinozeb acetate, or a mixture of these herbicides and alachlor, which have been used so far in pulse cultivation areas, is not satisfactory in terms of the sustainability of herbicidal effects and the phytotoxicity of pulses. do not have. Furthermore, during the growing season of beans, treatment with alloxydim or sethoxydim causes broad-leaved weeds to become worn out, and treatment with pentacine is undesirable as there is a risk of phytotoxicity to the beans. For these reasons, weeding during the growing season of legumes often involves mechanical and manual weeding two to three times each, with inter-tilling in between. However, this method is not desirable from the viewpoint of labor saving in agricultural work.

よる処理は棉に薬害の発生が懸念される。Cotton also has a slow initial growth rate, so weeds can overgrow, leading to reduced yields, and weeds in the later stages of growth can reduce the efficiency of mechanical harvesting or contaminate the harvest, causing a significant drop in quality. Pre-sowing treatment of cotton with dinitroaniline herbicides such as trifluralin in cotton cultivation areas has the disadvantage that it is less effective against weeds of the Asteraceae (Asteraceae, etc.) and Cyperaceae (Cyperaceae, etc.) . In addition, treatment with promethrin during the growing season of cotton causes grass weeds to become obsolete and is likely to cause chemical damage to cotton. Furthermore, there is concern that treatment with non-selective glyphosate may cause chemical damage to cotton.
このように豆類や棉栽培地の除草剤による雑草防除は必
ずしも満足のいくものではない。As described above, weed control using herbicides in legume and cotton cultivation areas is not always satisfactory.

の開発が望まれている。Therefore, we are developing a long-lasting herbicide that can reduce the number of times weeding during the growing season for field crops such as beans and cotton.In other words, it can be used before weeds emerge and in the early stages of germination in field crops, and can be used to control various grass weeds and broad-leaved weeds. It is desired to develop a herbicide for both soil and foliage treatment that exhibits excellent herbicidal effects, does not cause chemical damage to field crops, and is free from toxicity to humans, livestock, and fish and shellfish.

The five compounds are, respectively, grass weeds such as sorghum, hackberry, blackberry, grasshopper, and sorghum, as well as bindweed, bindweed, sorghum, convolvulus, ichito, commonweed, field mustard, Japanese knotweed, purslane, Japanese knotweed, purslane, whiteweed, broom grass, and sorghum. , acts as a herbicidal active ingredient against broad-leaved weeds such as Aspergillus chinensis. The herbicidal effect is most pronounced when Compound A is used in combination with Compound B, Compound C, or Compound Ri, which are urea compounds, and the herbicidal spectrum is expanded. In addition, the herbicidal effect was enhanced by compound A.
The above-mentioned urea-based compounds act so as to mutually strengthen each other while complementing their weaknesses without impairing their respective strengths. The effects tend to be more pronounced when used in small doses, but they can be safely used on field crops without causing any chemical damage.
