Description
Technical field
It is to be combined by propanil, dichloro quinolinic acid, for preventing and kill off paddy field weed the present invention relates to compound combination application.
Background technology
Chemical method weeding is agriculturally to control one of the main means of weeds.In recent years, due to some herbicide kinds
Large area is used alone, and already leads to many weeds and develops immunity to drugs.Increase herbicide dosage, when often result in crop generate medicine
Evil, it is ordinary that the underproduction reduces phenomenon.Meanwhile it is careless mutually complicated when weeds generation, variety classes weeds are mixed to be given birth to, and when weeds emergence
Between differ, seed, low age, advanced age weeds staggeredly occur, so herbicide kind be used alone when, can show in a certain respect
Defect and limitation.
Propanil is the highly selective contact killing type herbicide of amides, not only breaks up the photosynthesis of plant, but also is inhibited
Respiration and oxygen public affairs phosphorylation, interfering nucleic acid are synthesized with protein.To make the physiological function of sensitive plant by
It influences, accelerates dehydration, blade gradually dried-up, it is last dead.
Dichloro quinolinic acid is hormone-type quinoline carboxylic acid herbicide, and weeds poisoning symptom is similar to auxins effect, main
It is used to prevent barnyard grass and working life is very long, the 1-7 leaf phases are effective.Security of rice is good.
When propanil and dichloro quinolinic acid single use, there are certain defect and limitation.
The present inventor has made intensive studies the mixture of propanil and dichloro quinolinic acid, screens and tries in a large amount of formula indoor
It tests and on the basis of field medicine effect test, finds propanil and dichloro quinolinic acid progress mixture, it is interior in a certain mix proportion range
Apparent synergistic effect is shown to paddy field weed, improves to Security of rice, delays Weed Resistance to generate, through further grinding
Study carefully, completes the present invention.

Subject to asking.
In these embodiments, unless otherwise stated, all percentages are weight percentage.
One 44% propanil dichloro quinolinic acid wettable powder of embodiment
It is uniformly mixed entering in mixer after above-mentioned formula in proportion coarse crushing, then obtains 44% after air-flow crushing
Propanil dichloro quinolinic acid wettable powder.
2 24% propanil Dichloroquinolinic acid suspending agent of example of formulations
Above-mentioned formula is crushed in advance in proportion, adds in sand mill and grinds, system is allocated after high shear mixing
Obtain 24% propanil Dichloroquinolinic acid suspending agent.
3 15% propanil dichloro quinolinic acid water dispersible granules of example of formulations
By above-mentioned formula, dry pulverization process, granulation, drying, the obtained 40% propanil dichloro quinolinic acid of screening are water-dispersed in proportion
Property granula.
The 4 40% dispersible oil-suspending agent of propanil dichloro quinolinic acid of example of formulations
Solid material is added in sand mill by above-mentioned formula in proportion and is ground, high-speed stirred is blended in liquid material
Under, the 40% dispersible oil-suspending agent of propanil dichloro quinolinic acid is made.
Propanil combines the measurement of the synergy to weeds with dichloro quinolinic acid
In the built-in quantitative soil of the polypots of high 6cm, diameter 9cm, will moulded for examination 15~20 sowings of target weeds seed
Expect in alms bowl, be placed in greenhouse and cultivate after the fine earth of lid 0.5~1cm thickness, waits for that weeds grew to 3~4 leaf phases and carry out cauline leaf spraying treatment,
Per alms bowl spraying liquid 1mL, often processing is repeated 4 times, and sets the processing without medicament as control.Material is tried after processing is placed in training in greenhouse
It supports, the growing state of routine observation target weeds, range estimation target damage symptoms and growth inhibition situation after 15d, and claims overground part
Divide fresh weight, calculates fresh weight preventive effect (%).
Regression analysis is carried out to the logarithm of drug dose and the probability system of fresh weight preventive effect with DPS statistical analysis softwares, is counted
Calculate the ED of each medicament50, and according to the co-toxicity coefficient (CTC values) of Sun Yunpei's Method calculating mixture.
Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜, 120 tables
It is now summation action.
Five propanil of embodiment, dichloro quinolinic acid combination measure the synergy of barnyard grass
As can be seen from Table 1, propanil, dichloro quinolinic acid portfolio ratio 80:1~1:12 pairs of barnyard grass co-toxicity coefficients (CTC values)
120 are all higher than, synergistic effect, especially 5 are shown as：3 synergistic effects are the most notable.But propanil, dichloro quinolinic acid group composition and division in a proportion
Example is 80：1 and 1：24, co-toxicity coefficient (CTC values) shows as antagonism less than 120.
Table 1, propanil, the combination of dichloro quinolinic acid different proportion measure the synergy of barnyard grass
Six propanil of embodiment, dichloro quinolinic acid combination measure the synergy of lady's-grass
As can be seen from Table 1, propanil, dichloro quinolinic acid portfolio ratio 40:1~1:12 pairs of barnyard grass co-toxicity coefficients (CTC values)
120 are all higher than, synergistic effect, especially 5 are shown as：3 synergistic effects are the most notable.But propanil, dichloro quinolinic acid group composition and division in a proportion
Example is 80：1 and 1：24, co-toxicity coefficient (CTC values) shows as antagonism less than 120.
Table 2, propanil, the combination of dichloro quinolinic acid different proportion measure the synergy of barnyard grass
Seven propanil of embodiment, dichloro quinolinic acid composition for preventing and controlling paddy field weed field control effectiveness test.
Reagent agent and dispenser dosage：
The dispersible oil-suspending agent of (1#) 40% propanil dichloro quinolinic acid (25：15), 40 grams/acre of preparation dosage；
The dispersible oil-suspending agent of (2#) 40% propanil dichloro quinolinic acid (25：15), 60 grams/acre of preparation dosage；
The dispersible oil-suspending agent of (3#) 40% propanil dichloro quinolinic acid (25：15), 80 grams/acre of preparation dosage；
(4#) 34% propanil missible oil, preparation dosage 200 grams/acre (comparison medicaments)；
The dispersible oil-suspending agent of (5#) 25% dichloro quinolinic acid, preparation dosage 80 grams (comparison medicaments).
Application method：Rice terrace grassy weed 3-4 leaf phases, medicament are watered spraying.
20d investigation preventions result after dispenser：The dispersible oil-suspending agent of 40% propanil dichloro quinolinic acid (25：15) preparation is used
It is 92.47%, 98.06%, 100% to measure 60 grams/acre, 80 grams/acre, 120 grams/acre and prevent, and each treatment region is to rice without bad anti-
It answers；The prevention of 34% 400 grams/acre of propanil cream preparation dosage is 67.59%, rice leaf necrosis moderate poisoning performance；25% 2
Chloro-quinolinic acid 100 grams of preventive effects of dispersible oil-suspending agent preparation dosage are 84.50%, the slight poisoning performance of rice deformity.
Eight Resistence research of embodiment is tested.
The 50%-60% lethal doses for a concentration of barnyard grass that test medicine uses continue the barnyard grass reproduction test using growth,
10 generation barnyard grasses are handled repeatedly.If the liquid processing containing only auxiliary agent is blank control.Measure each medicament to 1st generation, the 5th generation and
The half lethal concentration EC of 10th generation barnyard grass50, by comparing EC of each treatment agent to 1st generation, the 5th generation and the 10th generation barnyard grass50Come
Barnyard grass is evaluated to change the drug resistance of reagent agent.
The resistant determination of 3 propanil of table, dichloro quinolinic acid and combinations thereof to barnyard grass.
As can be seen from the above table, propanil, dichloro quinolinic acid combination continuous processing 10 generation barnyard grass are aobvious to the resistance of combined treatment
It writes and is less than single use, barnyard grass has effectively been delayed to generate compound resistance.
