[PRIOR ART]-The use of herbicides can cause a lot of damage and also damage the cultivated plants. 'For example, depending on the concentration of the herbicide and its application, cultivation The nature and climatic conditions of plants and soil 'depend on the exposure period μ, temperature, and rainfall. Α The problems that prevent them and similar problems have been suggested. Many substances have been proposed as antagonizing the safety of the harmful effects of crops on cultivated plants. Agent (_machi) 'in other words' protects cultivated plants against this effect, but has no herbicidal effect on the weeds to be controlled. It is found that the recommended safeners are often in planting plants and herbicides. It has a very specific effect and some of the examples depend on the application. This means that the specific safener is often only suitable for specific cultivated plants and special types of herbicides or specific herbicides. SUMMARY OF THE INVENTION At present, it has been found that the compound II, tetra-terrestrial (2, 4-D) is suitable for protecting cultivated plants against the poisonous plants of clodidin-propargyl (clOdafop-prOpargyl). 200406151 Therefore, according to Knowing that the present invention proposes to select a ten-year herbicidal composition, in addition to including adjuvants such as a carrier, a solvent, and a wetting agent, $ includes a mixture of the following as an active ingredient: a) an effective amount of gefford —Propargyl and b) Two or four effective amounts of herbicide antagonism.

In the example of field treatment 200406151, it is generally applied from 1 to 150 g of two or four-land per hectare, preferably from 60 to 120 g of two or four-land per hectare. The application rate of cleffortol-propargyl is generally from 10 to 100 g / ha, but preferably from 20 to 60 g / ha. In order to broaden the range of weeds to be controlled, co-herbicides in the form of sulfonylides can be advantageously used. The following are particularly suitable: trinasulfuron, cinsulfuron, Bensulfuron, white sulfonon, halosulfuron, imaz sulfuron, prosulfuron, eth〇xysulfur. n), cyclosulfamuron and azimsulfuron, especially cinosulfuron. Therefore, the present invention also relates to a selective herbicidal composition which, in addition to including a formulation adjuvant such as Carriers, solvents and wetting agents also include the following mixtures as active ingredients: a) a herbicidally effective amount of clefoxol-propargyl, b) herbicide-antagonistic effective amounts of two, four, and c) Co-herbicides in the form of carbamide. For the purpose of administration, the composition of the di-, tetra-, or safener and clifol-propargyl is advantageously formulated together with adjuvants traditionally used in formulation technology. Emulsifiable concentrates, direct spray or dilutable baths, dilute emulsions, wettable powders, soluble powders, granules or capsules. Such formulations are described, for example, in No. 97/34485 9 to 13 pages. The formulation is prepared in a conventional manner, 200406151, for example, by intimately mixing and / or grinding the active ingredient with a liquid solid formulation adjuvant such as a solvent or a solid carrier. In addition, interfacial active compounds (surfactants) can be additionally used in the preparation of formulations. Solvents and solid carriers suitable for this purpose are mentioned, for example, on page 6 of 卯 97/34485. Suitable interfacial active compounds are non-ionic ' 1¼ ionic and / or anionic interfacial surfactants and interfacial agent mixtures which have good emulsification, dispersion and wetting properties. Examples of suitable anionic, nonionic and cationic surfactants are listed, for example, in wo 97/34485, pages 7 and 8. In addition, the preparation of the herbicidal composition according to the present invention is also a surfactant conventionally used in formulation technology, which is described in, in particular, nMcCutcheon, Detergents and Emulsifiers Annual MC Publishing Corp. 5 Ridgewood New Jersey 5 1981 'Stache' H.

The herbicidal formulations usually comprise from 0.1 to 99% by weight, in particular from 0.1 to 95% by weight, a mixture of active ingredients including clefoxol-propargyl and di- and tetra-tertene, from 1 to 99.9% by weight % Solid or liquid formulation adjuvants, and surfactants from 0 to 25% by weight, especially from 0.1 to 25% by weight. However, commercial products are usually better formulated as concentrates, and end users will typically use dilute formulations. The composition may also include additional additives, such as stabilizers, for example, 200406151 vegetable oils or epoxidized vegetable oils (epoxidized coconut oil, vegetable oil, or soybean oil), antifoaming agents, for example, stone ketone oil, antiseptic zibu pure adjustment Agents, adhesives and adhesives, and also include fertilizers or other active ingredients. There are many suitable methods and techniques for the use of two or four-ground protection of cultivated plants against the harmful effects of clefoxol-propargyl. The following are examples.

The composition system according to the invention is particularly suitable for controlling weeds in sown or transplanted rice fields, in which case the tank mixture is advantageously sprayed directly on the rice (leaf application). U) ^ Sword active ingredient release The mixture of cleffort and one, four-ground active ingredients is applied as a solution to granulated mineral carriers or polymeric particles (urea_formaldehyde) and dried.

茲常常更實用的為在即刻施用前，將克地福-炔丙基與混合夥伴二、四-地分開地製成調配物且然後以所欲混合比率，以於水中之π罐式混合物（tank mixture ) π之形式一起置於一撒藥機中。二、四-地保護耕種植物對抗克地福-炔丙基之植物毒性作用的能力係列舉說明於下列實施例。生物實施例實方fe例Β1 :出芽後（Post —emergence )試，驗：該試驗植物稻（Or/za sai/Fa)，科{ Echinochloa crus-gal 1 i )及千金子(Leptochloa chinensi s ) (戶斤有 15 200406151 在2—至3_葉期）係於稻田中以包括克地福UP 15)及：、四-地（商業上可獲# EC調配物）之嘴霧混合物處理: 茱部施用）。該試驗於施㈣12天進行評估（圓作用_ 植物已完全死亡；崎用=無植物毒性作用）。於此試驗中所獲得之結果列於下表中·· 對克地号作用 ---- 施用比率 (克/公頃）植物毒性（％) 稻稗千金子克地福 ------- 30 32__ 94 99 二、四-地 ----—— 60 0 0 0 克地福+二、四—地 30+60 18 96 Q8 該等結果顯示二、四-地能降低克地福對稻之植物毒性，而克地福對於最重要的稻雜草（稗及千金子）之高度除草作用仍維持。在此處所使用的施用比率中，二、四一地顯示對稻或稗及千金子沒有任何作用。 §活性成分混合物被依照前述調配物實施例製配時，可獲得相同之結果。 16It is often more practical to prepare the formulations of clefoxol-propargyl and the mixing partners two or four-ground separately before application and then mix the π-pot mixture in water at the desired mixing ratio ( The tank mixture is placed in a medicine dispenser together in the form of π. The series of two-, four-, ground-protected cultivated plants' ability to combat the phytotoxic effects of clefoxol-propargyl is explained in the following examples. Examples of biological examples: Example B1: Post-emergence test, test: The test plant rice (Or / za sai / Fa), family {Echinochloa crus-gal 1 i) and thousands of gold (Leptochloa chinensi s) (Houjin has 15 200406151 in the 2 to 3_leaf stage) is attached to the paddy field to include Cefford UP 15) and: 、 Four-ground (commercially available # EC formulation) mouth mist mixture treatment:部应用). The test was evaluated 12 days after application (round effect _ plant has completely died; zymesis = no phytotoxic effect). The results obtained in this test are listed in the table below. · Effect on Cretan ---- Application Rate (g / ha) Phytotoxicity (%) Rice Indica Thousand Gold Grafford ------- 30 32__ 94 99 Two, four-land -------- 60 0 0 0 Grafford + two, four-land 30 + 60 18 96 Q8 These results show that two, four-land can reduce clefal for rice Its phytotoxicity, while the high herbicidal effect of cleffort on the most important rice weeds (稗 and 千金) is maintained. Among the application ratios used here, two or four one showed no effect on rice or indica and thousands of gold. § The same result can be obtained when the active ingredient mixture is formulated according to the aforementioned formulation examples. 16
