Abstract
An expendable herbiciding composition for rice field contains component A (quinclorac), component B chosen from mefenacet, propisochlor, metolachlor, pretilachlor, butachlor and acetochlor, and component C chosen from pyrazosulfuron-ethyl, bensulfuron-methyl, azimsulfuron, etc.
Description
The present invention relates to some and have the Disposable herbiciding composition for rice field that improves performance and found, wherein contain dichloro quinolinic acid A and a specific herbicides compounds B and a specific herbicides compounds C who is selected from the C group compound who is selected from the B group compound as the weeding active principle based on a total technical conceive.
Paddy rice can be divided into inserting according to planting type plants rice, throws and plant three kinds of rice and Direct-seeding Rice (comprising water direct seeding rice and direct-sowing dry rice).Three kinds of paddy rice are very big to the resistivity difference of weed killer herbicide, and rice transplanting rice drug resistance is the strongest, and it is suitable that the rice drug resistance is planted in Direct-seeding Rice and throwing, and pesticide resistance is relatively poor.Therefore, every weed killer herbicide that can be used for Direct-seeding Rice safely also can be used for rice seedling naturally, more can be used for inserting planting rice.In addition, in the paddy rice that three kinds of modes are cultivated, Direct-seeding Rice plantation is the most convenient, but also the easiest farmland running to weeds.
In recent years, owing to lack and effectively to prevent and kill off the disposable herbicide of direct sowing rice field weeds, have in the production paddy rice broadcast preceding, broadcast the back seedling before and rice seedling carry out 2-3 chemical weed control, thereby formed the characteristics of direct sowing rice field weeding " difficulty is big, cost is high ", caused China's Direct-seeding Rice area to fluctuate always.Rice seedling owing to throw is planted back paddy rice part root system, and to be exposed to soil outer and can not have profundal zone to cover, and safety, to kill the disposable herbicide that grass spectrum and drug effect can meet the demands simultaneously also very few.
At present, domestic in Direct-seeding Rice with throw and to plant the weed killer herbicide list agent that rice promotes the use of and to be divided three classes: 1) processing soil treatment agent: mainly contain butachlor, the third careless amine, mefenacet, benthiocarb etc.: 2) cauline leaf inorganic agent: mainly contain dichloro quinolinic acid, Bentazon, methoxone etc. by period of using and method; 3) the soil treatment early stage cauline leaf inorganic agent behind the seedling of holding concurrently: mainly contain bensulfuron-methyl, pyrazosulfuron, cyclammonium sulphur grand (Cyclosulfamuron), Azimsulfuron etc.Above-mentioned processing soil treatment agent is mainly used in transplanting rice and prevents and kill off grassy weeds such as barnyard grass grass, and it is dangerous to be directly used in Direct-seeding Rice and rice seedling; Bentazon, methoxone are mainly used in and prevent and kill off rice field nutgrass flatsedge and broadleaved herb in the cauline leaf inorganic agent, and be invalid to grassy weed; And dichloro quinolinic acid is mainly prevented and kill off the barnyard grass grass, and is invalid substantially to nutgrass flatsedge and broadleaved herb; Bensulfuron-methyl, pyrazosulfuron, cyclammonium sulphur grand (cyclosulfamuron), Azimsulfuron that soil treatment is held concurrently in the cauline leaf inorganic agent are mainly used in various rice fields and prevent and kill off annual and perennial broadleaved herb and nutgrass flatsedge.In addition, kill the grass spectrum in order to enlarge, many producers have now also released many mixtures, kill (seeing " agriculture chemical registration bulletin compilation-1998 ", Chinese agriculture publishing house) such as (benthiocarb+bensulfuron-methyls) as fourth benzyl (butachlor+bensulfuron-methyl), benzyl dichloro (dichloro quinolinic acid+bensulfuron-methyl), dragon.These weed killer herbicides are that preventing and kill off of weeds in paddy field made contribution, but still there is such or such shortcoming, as to Direct-seeding Rice with to throw poor stability, the control grass phase plant the rice field short, low to the preventive effect of barnyard grass grass, a drug can not guarantee that still rice at whole growth periods avoids crop smothering etc.
In field observation for many years test, find, can kill the living weeds morning of having emerged after only using, can prevent and kill off the medicament of I weeds that emerge successively again, be expected to just realize that a drug removes the interference damage of various weeds in the direct sowing rice field comprehensively.
Based on above-mentioned this total technical conceive, have now found that compd A (dichloro quinolinic acid) and a specific herbicides compounds B and the Disposable herbiciding composition for rice field that the specific herbicides compounds C that is selected from the C group compound forms that is selected from the B group compound with herbicide effect, be used for direct sowing rice field and shown very surprising herbicidal effect, the wide grass that kills is composed, lasting lasting period and very high safety, but it uses once just safety, effectively, solve the crop smothering problem of direct sowing rice field economically, having broken present direct sowing rice field weeding needs the repeatedly situation of medication, greatly reduces the weeding cost of direct sowing rice field.
