Description
Technical field
The present invention relates to pesticide field, especially relate to a kind of lawn herbicide and using method having concurrently and acting on before bud and after bud.
Background technology
In recent years, urban public lawns are constantly built, and lawn area is also in continuous expansion, and weed problem is restriction turf management quality, affects the key factor of lawn scenery.
Current lawn is based on artificial control, and chemical prevention is auxiliary. Blanket type artificial weeding controlling weeds, cost accounting is high, and efficiency is low, and effect is extremely difficult to expection, and has a huge seed bank in soil, while manually weeding out the rank grass, is also taken out of by the seed of deep layer, and condition is once namely maturation is sprouted. This has resulted in the situation that weeds are pulled out more and more.
Turf weed huge number, on the south the Yangtze river basin, weeds mainly have kind more than 150. Including grassy weeds such as Herba Digitariae, Herba Eleusines Indicae, barnyard grass, list head grass, amur foxtail, Herba Imperataes; The broad leaved weeds such as Herba Erigerontis Annui, grasswort, Alternanthera philoxeroides, Carolina Cranesbill Herb, Herba Viviae Sativae, Conyza canadensis (L.) Cronq., Herba Galii Teneri, Herba Kalimeridis, DAWANHUA, Herba Capsellae; The dried tubers such as Rhizoma Cyperi, Herba Kyllingae, cyperus iria. Therefore any single herbicide is impossible to control whole Weed infestation. Such as, the chemical herbicide such as extensive use 2,4-D butyl ester, MCPA,MCP,methoxone preventing and treating broad leaved weed, dried tuber on current lawn, but grassy weed is invalid, and 2,4-D butyl ester environmental toxicities are bigger, continuous application 2,4-D butyl ester, can cause that around flower tree is dead.
The improper lawn generation poisoning that also can make selected by herbicide, even dead. Grass can be divided into cool-season grasses and season type grass, and some herbicides are to cold-season type lawn safety, but are then sensitive to warm-season turf. Vice versa. As the dogstail on the warm-season turf such as Bermuda grass, Korea lawn grass, broadleaved herb, dried tuber are all had good prevention effect by pyrazosulfuron, but the cold-season type lawns such as rye grass then can be produced poisoning. Therefore, the alternative herbicide in lawn some cold season types replaced is considerably reduced.
Herbicide is divided into preemergence herbicide and post-emergence herbicide, and before preventitious bud, weeding is much more laborsaving than weeds after preventing and kill off Seedling, and before preventitious bud, weeds need people's preemergence herbicide when not seeing weed germination, could obtain initiative. The situation of reality is, due to region, environment, weather change, the time of weed germination is not quite similar, if preventing and treating is too early, As time goes on, preemergence herbicide reduced activity in soil, preventive effect also can be deteriorated. If preventing and treating is too late, missing emergence peak, weeds sprout major part, and preventing and treating does not just have not in all senses, because the seed not germinateed only is worked by preemergence herbicide. Therefore selecting long-acting lasting preemergence herbicide, after having again bud concurrently, the herbicide of herbicide effect is particularly important simultaneously.
Summary of the invention
For solving problem above, the invention provides a kind of formula reasonable, preventive effect substantially has the lawn herbicide and using method that act on before bud and after bud concurrently.
A kind of have concurrently before bud and the lawn herbicide of effect after bud, its special spy is in that: the formula of herbicide, calculate by mu, be made up of following preparation, 50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% bentazone water preparation 200 milliliter/mu, 96% S-metolachlor cream 100 milliliter/mu.
A kind of using method having the lawn herbicide acted on before bud and after bud concurrently, is be watered to 50,000 grams/acre after mixing by above-mentioned pharmaceutical formulation; The mode of preparation mixing is first to add the half that need to add water inventory in a device, then 50% dichloro quinolinic acid wettability wettable powder, 48% bentazone water preparation, 96% S-metolachlor cream it are sequentially added into, often add a kind of preparation to stir, then next preparation is added, be watered after mixing and be evenly stirred until total amount/mu, it is thus achieved that herbicide spray in green surface; For ensureing best preventive effect, should irrigate in the previous day, use during the humidity of earth's surface, it is impossible to the dispenser when there being occluded water, otherwise can affect drug effect; Spraying time is before 3-4 summer in month autumn weed germination; Before the weed germination of 9-10 month Winter-Spring, each sprinkling is once; According to circumstances 7, August fill spray and spill once, maximum dispensers in a year three times, ideal effect can be reached.
Present invention have the advantage that
1, the herbicide of the present invention adopts three kinds of medicament mixing, broad weed-killing spectrum, prevents and treats success rate height. To grassy weeds such as Herba Digitariae, Herba Eleusines Indicae, barnyard grass, Semen Euphorbiae, Herba Setariae Viridis; The broad leaved weeds such as Herba Erigerontis Annui, grasswort, Alternanthera philoxeroides, Carolina Cranesbill Herb, Herba Viviae Sativae, Conyza canadensis (L.) Cronq., Herba Galii Teneri, Herba Kalimeridis, DAWANHUA, Herba Capsellae; The dried tubers such as Rhizoma Cyperi, Herba Kyllingae, cyperus iria all have good prevention effect.
2, the Herbicidal composition of the present invention is reasonable, and to people and animals' fanout free region, environmental pollution is little. Safety to cold-season-type and warm-season turf, will not produce poisoning under conventional amount used.
3, (stem and leaf) herbicide effect after (soil closing) and bud before the herbicide of the present invention has bud concurrently, long-acting persistently. Significantly weaken and administer the impact on weed control too early or too late.
4, the present invention saves cost, cheap, includes the every square meter of labour cost less than 0.1 yuan. And have soil at present concurrently and close and the herbicide of stem and leaf process double effects, as golden hundred shows etc. are pacified on state light Zhuo Er, level ground, its cost accounting is all more than 0.18/ square meter. And they all can not act on warm-season turf, after dispenser, can cause that warm-season turf is withered, even dead.
5, flexible operation of the present invention, easy to use, can according to region, environment, the motor-driven selection spraying time of weather.
Detailed description of the invention
Herbicidal composition provided by the invention, matched proportion density and using method thereof are obtained by following five groups of tests.
Test 1: the different preemergence herbicide impacts on Kill weeds effect
Preemergence herbicide mainly has prodiamine, Tupersan, S-metolachlor, alachlor, Acetochlor etc., because using prodiamine, Tupersan costly, consider cost factor, only compare S-metolachlor, alachlor, three kinds of preemergence herbicides of Acetochlor here.
Test period is in mid-September, 2013, and place is Mu Cheng park, Jingjiang City of Jiangsu Province, and method is as follows:
EXPERIMENTAL DESIGN is divided into two factors. Factor I is 96% S-metolachlor cream, 48% alachlor cream, three kinds of herbicides of 50% acetochlor ec. 3 kinds of application concentrations of factor Ⅱ, respectively 96% S-metolachlor cream 25 milliliter/mu, 50 milliliters/mu, 100 milliliters/mu;48% alachlor cream 150 milliliter/mu, 300 milliliters/mu, 600 milliliters/mu; 50% acetochlor ec 50 milliliter/mu, 100 milliliters/mu, 200 milliliters/mu. Three kinds of preparations are labeled with low concentration, middle concentration, high concentration respectively. 96% S-metolachlor cream is watered 45,000 grams/acre, 48% alachlor cream is watered 35,000 grams/acre, 50% acetochlor ec is watered 50,000 grams/acre, (amount of being watered is the average recommending consumption above), uniformly it is sprayed on lawn, irrigation operation is carried out the previous day, to ensure optimum medicine efficacy at spraying herbicide. Spray clear water as comparison. Before bud herbicidal effect (enclosed) in mid-April, 2014 randomly select 3 meters long, 3 meters wide scope investigate, set three repetitions altogether. Enclosed=(comparison weeds strain number-process weeds strain number)/comparison weeds strain number is multiplied by 100%. Data SPSS statistical software carries out significance of difference analysis, its result such as table 1 below.
Table 1
Note: lower case difference represents lateral comparison significant difference, capitalization difference represents longitudinal comparison significant difference, P < 0.05.
P value and letter a, b, c are by SPSS statistical software when the significance of difference is analyzed and automatically generate, P value and Sig value, Sig=significance, look like for significance, and P value represents statistical significance. It it is a kind of method of estimation of real result degree. In specialty, P value is a declining indicator of credible result degree, and P value is more big, we more must not believe that the association of variable in sample be overall in the reliability index of each variable association. As P=0.05 point out variable association in sample have 5% be likely due to what occasionality caused. I.e. equal onrelevant between aleatory variable in hypothetical universe, we repeat similar experiment, it is found that have 1 experiment in about 20 experiments, the variable association that we study will equal to or be better than our experimental result. In many research fields, the P value of 0.05 is typically considered the border level of acceptable mistake. P shows that less than 0.05 experimental result is true and reliable. Letter a, b, c itself does not have any implication. They be by each other whether relatively embody difference notable. Will according to more whether abc has significant difference, it is only necessary to compare whether two groups of letters represented have overlap. Such as between a, b, c three, different, all there were significant differences mutually, but compares for ab and a or ab and b compares, and is respectively arranged with repetitive letter, so two pairs do not have significant difference. But just there were significant differences (below table is explained identical) between ab and c.
As seen from the above table, use high concentration 96% S-metolachlor cream, i.e. 100 milliliter/mu, reach the lawn sealing effect of the best. Therefore, we select 96% S-metolachlor cream as the preemergence herbicide of complex preparation.
Test 2: the post-emergence herbicide of the variable concentrations impact on Kill weeds effect.
With 50% dichloro quinolinic acid wettable powder (25 grams/acre, 50 grams/acre, 75 grams/acre three kinds of concentration), the 48% bentazone water preparation (100 grams/acre, 150 grams/acre, the 200 grams/acre three kinds of concentration) impact on Kill weeds effect. Two kinds of preparations are labeled with low concentration, middle concentration, high concentration respectively. The preparation of ad eundem concentration is sufficiently mixed, and is watered 40,000 grams/acre, is uniformly sprayed on green surface after being sufficiently stirred for mixing. Irrigation operation is carried out the previous day, to ensure optimum medicine efficacy at spraying herbicide. After 10 days, 20 days, 30 days, randomly choose 3 meters long, 3 meters wide scope investigate, if three repetitions.Before weeding rate=(before preventing and treating weeds strain number after weeds strain number-preventing and treating)/preventing and treating, weeds strain number is multiplied by 100%. Data SPSS statistical software carries out significance of difference analysis, and result is shown in table 2 below
Table 2:
Note: different letter representation significant differences (P < 0.05)
As seen from the above table, mix preparation in higher concentrations to broad leaved weed, that dried tuber prevents and kill off rate is the highest. And the rate of preventing and kill off to dogstail, high concentration and middle concentration difference are little, after dichloro quinolinic acid, two kinds of reagent mixing of bentazone, generally will not there is potentiation, it is considered to cost factor, select 50% dichloro quinolinic acid wettable powder 50 grams/acre, as optium concentration. Therefore, the optium concentration of the two is 50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% 200 grams/acre of bentazone water preparation.
Binding tests 1 and test 2, by 50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% bentazone water preparation 200 milliliter/mu, 96% S-metolachlor cream 100 milliliter/mu, the complex preparation of composition, have the matched proportion density effect of the best.
Test 3: the mensuration of the amount of being watered under best concentration ratio:
Preemergence herbicide drenches among soil, eliminates the seed in soil, its preventive effect will be made best, then must keep higher soil moisture, medicinal liquid reaches the embedded depth of standard, therefore needs the higher amount of being watered, and this dilutes the concentration of post-emergence herbicide in complex preparation virtually. The amount of being watered of above-mentioned two test is the respective routine amount of being watered before pestsides synthesis, for ensureing weeding (soil closings) effect before bud, does not affect herbicidal effect after bud simultaneously, then must the best amount of being watered of preparation after mixing be measured. Test method is as follows:
50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% bentazone water preparation 200 milliliter/mu, 96% S-metolachlor cream 100 milliliter/mu, be watered after mixing to 30,40,50,60 kilograms/per mu even be sprayed on green surface. Measure the weeding rate under the different amount of being watered and enclosed. Enclosed=(comparison weeds strain number-process
Weeds strain number)/comparison weeds strain number be multiplied by 100%. Before weeding rate=(before preventing and treating weeds strain number after weeds strain number-preventing and treating)/preventing and treating, weeds strain number is multiplied by 100%. Data SPSS statistical software carries out significance of difference analysis, and result is shown in following table:
Table 3
Note: lateral comparison difference letter representation significant difference (P < 0.05).
As seen from table, the amount of being watered is when 30-50 thousand grams/acre, and herbicide herbicidal effect does not have significant difference, but when the amount of being watered is at 60,000 grams/acre, herbicidal effect significantly reduces. Sealing effect then along with the increase of the amount of being watered in obvious ascendant trend, when 50,60,000 grams/acre, difference is little, but because when 60,000 grams/acre, herbicidal effect is relatively low, therefore selects 50,000 grams/acre as the best amounts of being watered.
Test 4: Winter-Spring weed control efficacy measures
Weed germination type is divided into Winter-Spring sprouting type and Xia Qiu sprouting type, be typically chosen in annual 3, April and 9, two time periods of October respectively use once, just can reach to eliminate the purpose of weeds a year and a day.
But specifically when spraying medicine can make herbicidal effect reach optimum, depends on the factors such as region, environment, weather. Therefore, we have done following two groups of tests, are measure the herbicidal effect that after three kinds of reagent mix, the complex preparation of composition is real on the one hand, and that determines the best on the other hand prevents and kill off the time.
2014 9, test in Mu Cheng park, Jingjiang City of Jiangsu Province October, method is as follows:
After respectively 50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% bentazone water preparation 200 milliliter/mu, 96% S-metolachlor cream 100 milliliter/mu being mixed on JIUYUE 5 days, JIUYUE 15 days, JIUYUE 25 days, October 5, it is watered to 50,000 grams/acre, after being sufficiently stirred for mixing, is uniformly sprayed on green surface.Irrigation operation is carried out the previous day, to ensure optimum medicine efficacy at spraying herbicide. Respectively at 10 days, 20 days, 30 days " Invest, Then Investigate " herbicidal effects of spraying herbicide. The region selecting long 3 meters, wide 3 meters is investigated, if three repetitions. Weeds strain number * 100% before weeding rate=(before preventing and treating weeds strain number after weeds strain number-preventing and treating)/preventing and treating. The mensuration of weeding before bud (closing) effect to spray 50,000 grams/acre of clear water as comparison, investigates sealing effect in mid-April, 2015. The region randomly choosing long 3 meters, wide 3 meters equally is investigated, if three repetitions. Enclosed=(comparison weeds strain number-process weeds strain number)/comparison weeds strain number * 100%. Spray clear water as control treatment. Data SPSS statistical software carries out significance of difference analysis, its result such as following table.
Table 4: the rate of preventing and kill off of different time spraying herbicide and enclosed compare
| The process time | Prevent and kill off rate (%) | Enclosed (%) |
| JIUYUE 5 days | 92.62 a | 83.53 ab |
| JIUYUE 15 days | 91.83 a | 87.45 a |
| JIUYUE 25 days | 93.37 a | 86.39 a |
| October 5 | 87.85 ab | 73.48 b |
Note: different letter representation significant differences (P < 0.05)
Result shows: all have at JIUYUE 5 days, JIUYUE 15 days, JIUYUE three time period spraying herbicides on the 25th
There is a good herbicidal effect, and three's difference is little, but after October 5 spraying herbicide, preventive effect is relatively low, it is possible to temperature reduces the performance that have impact on drug effect. Sealing effect after JIUYUE 15 days and JIUYUE dispenser on the 25th is better than JIUYUE 5 days, and the sealing effect after dispenser on October 5 declines more, illustrates that most of Winter-Spring weeds sprouted before October, prevents and treats just nonsensical after this.
We also compare simultaneously and with herbicide of the present invention, dogstail, broadleaved herb, the rate of preventing and kill off of three kinds of dissimilar grass of dried tuber and enclosed have been tested. Test effect is the dogstail on average rate of preventing and kill off is 88.56%, and broadleaved herb is 96.34%, and dried tuber is 93.13%. Dogstail enclosed is 98.12%, and broadleaved herb is 78.24%, and dried tuber is 84.15%.
In sum: can play at 9-10 month any time period spray herbicide medicine of the present invention and well prevent and kill off and sealing effect, wherein 15 to 25 front and back spray medicine preventive effects of JIUYUE are best. Dogstail, broadleaved herb, dried tuber are all had by this herbicide prevents and kill off and sealing effect preferably, and wherein to prevent and kill off rate the highest for broadleaved herb, and the sealing process of dogstail is best.
Test 5 autumn in summer weed control efficacies to measure
2015 3, test in Mu Cheng park, Jingjiang City of Jiangsu Province April, method is as follows
After respectively 50% dichloro quinolinic acid wettable powder 50 grams/acre, 48% bentazone water preparation 200 milliliter/mu, 96% S-metolachlor cream 100 milliliter/mu being mixed on March 5, March 15, March 25, April 5, it is watered to 50,000 grams/acre, after being sufficiently stirred for mixing, is uniformly sprayed on green surface. Irrigation operation is carried out the previous day, to ensure optimum medicine efficacy at spraying herbicide. Respectively at 10 days, 20 days, 30 days " Invest, Then Investigate " herbicidal effects of spraying herbicide. The region selecting long 3 meters, wide 3 meters is investigated, if three repetitions. Weeds strain number * 100% before weeding rate=(before preventing and treating weeds strain number after weeds strain number-preventing and treating)/preventing and treating. The mensuration of weeding before bud (closing) effect to spray 50,000 grams/acre of clear water as comparison, investigates sealing effect in mid-October, 2015. The region randomly choosing long 3 meters, wide 3 meters equally is investigated, if three repetitions. Enclosed=(comparison weeds strain number-process weeds strain number)/comparison weeds strain number * 100%. Spray clear water as control treatment.Data SPSS statistical software carries out significance of difference analysis, its result such as following table.
Table 5: the rate of preventing and kill off of different time sections spraying herbicide and enclosed compare
| The process time | Prevent and kill off rate (%) | Enclosed (%) |
