Description
Technical field
The invention belongs to agricultural herbicide technical field, particularly relates to a kind of paddy field Herbicidal combinations and answer
With.
Background technique
Rice is a big important cereal crops, and cultivated area is extensive, growing environment is various, and weeds in field often mixes life
It is long, including a variety of annual or perennial gramineae weed, broadleaf weeds and nutgrass flatsedge.Currently, there are no a kind of weeding single dose energy
Enough while completely removing these weeds.Meanwhile as single dose herbicide kind is in the increase of paddy field frequency of use and dosage,
Safety to rice, the influence to soil environment, weak tendency weeds become strong and tolerant weeds and gradually produce the problems such as preventing and kill off
It is raw, by being the effective way to solve the above problems by the herbicide mixture of different role mechanism.
Publication No. CN102464611A discloses a kind of herbicides compounds with high activity of weeding, to rice
Field cauline leaf, which is sprayed or spreads fertilizer over the fields, can efficiently control the broadleaf weeds such as Monochoria korsakowii, Monochoria vaginalis, arrowhead, such compound is as a kind of
New herbicide enriches existing herbicide kind, has very big application value, but since herbicidal compounds are to rice
Field gramineae weed prevent and kill off activity it is relatively low, need to improve dosage and thoroughly prevented and kill off.Under higher dosage,
The compound has certain phytotoxicity risk to rice, this limits the popularization and application of the medicament to a certain extent.
Propanil is a kind of selectivity, contact killing type, stem and leaf treatment after seedling herbicide, to paddy field annual gramineous weed,
Nutgrass flatsedge, such as barnyard grass, semen euphorbiae prevent and kill off effect with preferable, but poor to the effect of preventing and kill off of paddy field broadleaf weeds.It is killed
Grass spectrum and herbicides compounds disclosed in CN102464611A have complementary characteristic.Cyhalofop-butyl alternatively property, interior suction
Type, stem and leaf treatment after seedling herbicide, it is similar with propanil, activity is prevented and kill off with higher to paddy field gramineae weed, but to wealthy
Leaf weed control activity is lower, using being subject to certain restrictions.
Summary of the invention
The present invention carries out the herbicide for paddy field such as herbicides compounds disclosed in CN102464611A and propanil, cyhalofop-butyl
Mixture research, proposes a kind of binary composition of herbicide, it is therefore an objective to provide a kind of preferable weeding of agent for removing grass in paddy field effect

Bioactivity example
11 greenhouse activity of example measures test examples
(1) test material culture and processing method
It is 7cm equipped with nutrition that quantitative weed seed (barnyard grass, rice barnyard grass, Monochoria korsakowii, bur beggar-ticks) is sowed at diameter respectively
In the dixie cup of soil, broadcast after rear earthing, suppression, water drenching in hot-house culture.Gramineae weed is long to 1.5~2 leaf phases, broadleaf weeds 2
~4 leaf phases, cauline leaf spraying treatment when 8~10cm high of nutgrass flatsedge, test set 3 repetitions.It is put in after processing in greenhouse according to a conventional method
Management.
(2) test result investigation and evaluation
According to weeds emergence, suppressed or dead situation is grown, 20 days after processing, investigate each processing to for examination
The fresh weight preventive effect of weeds and comprehensive range estimation preventive effect.
The composition of two kinds of components proposed by the present invention uses Gowing method to the evaluation of the synergy of weeds, calculates public
Formula are as follows: E=X+Y-XY/100.
In above formula: X, Y are that component A, B is the Weed-control effect under a certain dosage, and E is after component A, B is mixed to Weed-control effect
Desired value.
If measured value, which is greater than, calculates resulting desired value E by above formula, then it represents that composition has synergistic effect；Measured value
Less than E, then show that composition has antagonism；If measured value calculates resulting desired value E close to by above formula, then it represents that two
Kind component has summation action.
(3) herbicidal effect of the composition in greenhouse
Experimental result shows (table 1,2,3,4), new carbamate herbicide 2- (the chloro- 5- of 2- (3- chloro-5-trifluoromethylpyridine -2-
Base)-N- methyl benzenesulfonamide) ethyl acetate and cyhalofop-butyl, propanil to the preventive effect of grass family and broadleaf weeds not
Together, new carbamate herbicide 2- (the chloro- 5- of 2- (3- chloro-5-trifluoromethylpyridine -2- base)-N- methyl benzenesulfonamide) ethyl acetate pair
Broadleaf weeds preventive effect is better than other herbicides, but, the two poor compared with cyhalofop-butyl, propanil to the preventive effect of gramineae weed, nutgrass flatsedge
Mixture has certain complementation.According to the mixed effect of two kinds of compositions in the Gowing method evaluation present invention, as the result is shown
Preventive effect measured value is all larger than theoretical value, shows that the type of its synergy belongs to synergy.
The fresh weight preventive effect to gramineae weed is applied alone in 1 composition of table and its each component
The fresh weight preventive effect to broadleaf weeds is applied alone in 2 composition of table and its each component
The indoor range estimation preventive effect to gramineae weed is applied alone in 3 composition of table and its each component
The indoor range estimation preventive effect to broadleaf weeds is applied alone in 4 composition of table and its each component
12 field control effectiveness test example of example
(1) reagent agent: the composition in example 2,6,9,10.
Comparison medicament: preparing in a conventional manner or commercially available 20% component A1:2- (the chloro- 5- of 2- (the chloro- 5- trifluoro of 3-
Picoline -2- base)-N- methyl benzenesulfonamide) ethyl acetate suspending agent；10% component B1 (cyhalofop-butyl) missible oil；30%
Component B2 (propanil) missible oil (commercially available).
(2) for studying object: (after rice transplanting slow seedling, each processing carries out water proof processing, single list with PVC partition to transplanting rice
It fills).
(3) control object: paddy field dominant weed, such as barnyard grass, Monochoria korsakowii, angustifolia arrowhead herb, bur beggar-ticks, nutgrass flatsedge.
(4) test method: according to experimental plot area, the various medicaments of precise are watered dilution, using Singapore's benefit agriculture
HD400 knapsack hand sprayer carries out paddy field cauline leaf spraying treatment, spouting liquid 450L/ha (30kg/ mus), i.e. 45ml/m2。
(5) preventive effect is investigated: 20d range estimation investigation prevents and kill off situation and paddy growth shape to each processing cell weeds after processing
Condition.
(6) field control effectiveness test result
Test result shows (table 5) that the present composition all has paddy field gramineae weed, broadleaf weeds and nutgrass flatsedge
Preferable preventive effect, and synergistic effect is obvious.
5 field control effectiveness test result of table
The rice is doing well for the cell respectively handled, has no apparent phytotoxicity phenomenon, illustrates the present composition for preventing and kill off
Paddy field weed, it is safer to paddy growth.
