Description

1247582 Di, invention description: [Technical field to which the invention pertains] The present invention relates to a novel herbicide composition and a preparation method thereof. [Prior Art] Many herbicides are often used in the control of weeds in paddy fields, including butyl larvae (feline amines) and tickonyls (genus genus). But butyl lavender is a widely used herbicide 剡 ' used for inserting 秧 2 2 to 4 days after the cover of the surface, the water surface is maintained at a depth of 3 to 5 cm, and then the butyl lacquer emulsion (E_siflable café she (referred to as EC) or granules ^) A sprinkle cloth and protect & water in the paddy field to transplant. However, due to the wide variety of weeds and the high incidence rate, the T-grass weeding method, the long-acting (10) grass and the multi-grass control effect at the same time, this development has a long-lasting and wide-spread mix. Formulated herbicide. For the rice-derived-year-old grasses and some broad-leaf turn, the single-chore kelly grass has a certain treatment, but for the sedge plant that occurs at the same time before or during the attack, it cannot be controlled. The treatment of other pharmaceuticals is a waste of time for the application of the two pesticides for the farmers, so the value of the economic and practical effects of the mixture is developed. In Chenle, there is a single-agent or mixed-sword sword. Among them, mixed preparations refer to two types; two or more kinds of active ingredients are turned into binary or multi-component mixtures. Those who have two persuasive ingredients are called binary mixtures, and those with more than three active ingredients are called ternary elements. The meaning of this is: I avoid the problem of barrel mixing (but ankmix) when using single agent. Different active ingredients and dosage forms In order to save time and labor, the pesticide users often spray a variety of 1247552 in use, and then spray them. This method may cause physical or chemical changes due to different domain types and dosage forms. Physically, there are often emulsifications such as _ming, sedimentation, agglutination (f)〇cculati〇n), phase inversion, coalescence, and 〇stwakl ripening. , resulting in uneven mixing phase 'cannot evenly spread or even block the nozzle when in use. Chemical changes can cause decomposition of effective components to cause reduced efficacy and other undesirable conditions. 2. Increase the scope of use The active ingredients of the mixed preparation towel will be enlarged due to the difference in the fine objects, so that the effect of saving time and labor can be achieved. 3. Reduce phytotoxicity

Many varieties of medicinal herbs have phytotoxicity on crops, and adding other active ingredients to reduce phytotoxicity is also one of the solutions D. [Invention] The technology of the present invention is directed to the drawbacks of conventional herbicides. A new type of mixed herbicide composition, which has long-lasting and wide-ranging effects, and can save farmers time and cost. The main object of the present invention is to provide a herbicidal composition comprising an effective amount of butyl ketone (Aq3Ut〇xymethyl-2 chl〇r〇_2, 6, _dieth cadmium (1)d; common name:

Butachlor's capsule suspension (micr〇encapsuiated s (10)-; cs for short), and effective i's Taicao 4 (l-(l-methyl small phenylethyl)-3«p-tolylurea; common name: Daim_n) a mixture of aqueous suspensions (suspensi〇nc〇ncentrates; abbreviated as sc), and the 1247582 herbicide composition contains 0.0005%~43.985% (w/w) of butyl lavage, and _〇5%~43 · 985% (w/w) of the grass dragon. Preferably, the active ingredient of the herbicidal composition comprises 5% to 275% (w/~) butyl lapcap, and the best contains 20% (w/w) butyl lapcap. The pre-escape herbicide composition preferably contains 3% to 16.5% (w/w) of ticks, and the best system contains 12% (w/w) of ticks. The structural formula (I) of the above butyl serrata is as follows: ch2ch3 ^_n/C〇CH2CI ^==m\ CH2〇(CH2)3〇H3 ch2ch3 The structural formula (II) of the above-mentioned T. chinensis is as follows: 〇

The concentration of the capsule suspension of gossip h3 :b_NH 0~Ι_ΝΗ CH3 and 曲 MT基拉草 is preferably G1%~95% (call, best / then 32%) The concentration is preferably 0.1%~95% W/w) 'The optimum concentration is 40% (w/w). ^The weeding compound, the feed, contains the appropriate separation, tackifier. The agent, the anti-caries water plus the traits and tenderness, the water solitude, the fine knife U, the god, the viscosity, the low temperature stability, the heat storage stability, etc. Another object of the present invention is to provide a herbicide composition Preparation method, package 4 1247582 column steps. (a) separately prepared a specific concentration of butyl ^ Qian read grass water suspension;) ^ butyl butyl rubber «liquid-like grass Long Xi Ganfan heart 钊And (c) add appropriate, he formulates and mixes well. The concentration of the butyl sylvestris in the above = step is expected to be α1% to 95% (w/w) ‘the optimum concentration is 32% (w/w). The above 〇1 ^ ^ concentration is preferably _i / Q % / 〇 (w / w), and the optimum concentration is 4 〇 % (w / w). The formulation described in step 4 (C) may be selected from the group of feet: a dispersant, a tackifier, a bactericide, an anti-, and an anti-water. The age of the invention may be determined by Wei-Bingling to make the herbicide of the secret, and the herbicidal effect of the layer is further improved. At the same time, it can be mixed with insecticides, agents, nematicides, fungicides, plant growth regulators, and the like. [Embodiment] A herbicidal composition of the present invention is further understood by the following examples, and is not intended to limit the scope of the invention. The various formulation agents used in the following examples are as follows:
