Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, to provide a kind of utilization ratio of drug high, absorb continuation good, to the seeds of easily a large amount of resinosis after insect pest and the wound processing especially method for filling of effectively preventing damage by disease and insect.
The object of the present invention is achieved like this, a kind of method for filling of preventing and treating trees damage by disease and insect, comprise make up a prescription, boring, dispenser, envelope hole operation, specifically have following steps:
A, make up a prescription: water 1500 ~ 2000 weight portions, chrysanthemum ester insecticide 3 ~ 6 weight portions, organophosphorus insecticide 3 ~ 6 weight portions, hydrolase 1 ~ 3 weight portion, mix above-mentioned raw materials rear standby;
B, boring: under oblique on the trunk apart from more than ground 3m, be 40 ~ 50 ° of angular bit fill orifices, aperture 6 ~ 8mm, dark 4 ~ 5cm, the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground≤5cm, bore a hole, the every increase of diameter of a cross-section of a tree trunk 1.3 meters above the ground 5cm, increases a hole, Kong Yukong should interlock and rises in the shape of a spiral and be uniformly distributed in week around tree, and upper and lower distance is interval 10cm at least;
C, dispenser: from tree bud sprout to period of dormancy be the dispenser phase, every hole medication 3 ~ 6ml, every medication in 15 ~ 20 days once, continuous administration 3 ~ 5 times;
D, Feng Dong: after each dispenser, temporary enclosed treehole, last dispenser is complete, and treehole is sealed completely.
Evidence: method for filling utilization ratio of drug of the present invention is high, is not set height greatly and the impact of weather conditions.Hydrolase in formula has decomposition to the resin of tree body secretion, particularly evident in the result of use in summer that temperature is higher, can significantly reduce due to insect pest and wound and process the impact of a large amount of resinosis of caused trees on drug permeability, drug absorption continuation is good.In addition, method for filling safety and environmental protection of the present invention, can be to environment, and easy to operation, and the seeds that easily produce wound resin, cause a large amount of resinosis after insect pest and wound are processed, as cdear etc. has obvious control efficiency.
Embodiment
Below in conjunction with example, the present invention is further illustrated, but never in any form the present invention is limited, and any conversion or the improvement based on training centre of the present invention, done, all fall into protection scope of the present invention.
Method of the present invention, comprise make up a prescription, boring, dispenser, envelope hole operation, specifically have following steps:
A, make up a prescription: water 1500 ~ 2000 weight portions, chrysanthemum ester insecticide 3 ~ 6 weight portions, organophosphorus insecticide 3 ~ 6 weight portions, hydrolase 1 ~ 3 weight portion, mix above-mentioned raw materials rear standby;
B, boring: under oblique on the trunk apart from more than ground 3m, be 40 ~ 50 ° of angular bit fill orifices, aperture 6 ~ 8mm, dark 4 ~ 5cm, the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground≤5cm, bore a hole, the every increase of diameter of a cross-section of a tree trunk 1.3 meters above the ground 5cm, increases a hole, Kong Yukong should interlock and rises in the shape of a spiral and be uniformly distributed in week around tree, and upper and lower distance is interval 10cm at least;
C, dispenser: from tree bud sprout to period of dormancy be the dispenser phase, every hole medication 3 ~ 6ml, every medication in 15 ~ 20 days once, continuous administration 3 ~ 5 times;
D, Feng Dong: after each dispenser, temporary enclosed treehole, last dispenser is complete, and treehole is sealed completely.
Chrysanthemum ester insecticide described in steps A is 5 ~ 20% sumicidin, cypermethrin or fenpropathrin milk oil.
Organophosphorus insecticides described in steps A is 40 ~ 50% dimethoate emulsifiable concentrate or omethoate emulsifiable solution.
Hydrolase described in steps A is lipase.
Described lipase is Resinase A.
In reagent combination described in steps A, also can further add penetrant 1 ~ 3 weight portion.
Described penetrant is organic silicon surfactant or azone.
Described organic silicon surfactant is trisiloxanes APEO.
Fill orifice described in step B is no more than at most 6.
The trees diameter of a cross-section of a tree trunk 1.3 meters above the ground described in step B refers to the overhead diameter at 1.0 ~ 1.3m place of trees trunk.
In trees section when deformity,, the diameter of a cross-section of a tree trunk 1.3 meters above the ground refers to the overhead mean value of 1.0 ~ 1.3m place maximum gauge and minimum diameter of trees trunk.
The dispenser phase described in step C is 4 ~ October preferably.
Described in step D, the complete sealing treehole of dispenser can adopt yellow mud or resin.
embodiment 1
Reagent combination: water 1500 weight portions, 5% fenvalerate missible oil 3 weight portions, 40% dimethoate emulsifiable concentrate 3 weight portions, Resinase A 1 weight portion, trisiloxanes APEO 1 weight portion.Above-mentioned raw materials is mixed rear standby.
Trees diameter of a cross-section of a tree trunk 1.3 meters above the ground 4cm, is one of 40 ° of angular bit fill orifice under oblique on the trunk apart from more than ground 3m, aperture 6mm, dark 4cm.Selecting late April is the dispenser phase, every hole medication 3ml, every medication in 15 days once, continuous administration 3 times.After each dispenser, with plastic film temporary enclosed treehole, last dispenser is complete, with yellow mud, treehole is sealed completely.
embodiment 2
Reagent combination: water 2000 weight portions, 15% permethrin milk oil 4 weight portions, 45% DDT EC 4 weight portions, Resinase A 2 weight portions, trisiloxanes APEO 2 weight portions.Above-mentioned raw materials is mixed rear standby.
Trees diameter of a cross-section of a tree trunk 1.3 meters above the ground 15cm, is 45° angle under oblique on the trunk apart from more than ground 3m and bores 3 of fill orifices, aperture 7mm, and dark 5cm, Kong Yukong should interlock and rises in the shape of a spiral and be uniformly distributed in week around tree, and upper and lower distance is interval 15cm at least.Selecting late June is the dispenser phase, every hole medication 4ml, every medication in 18 days once, continuous administration 4 times.After each dispenser, with plastic film temporary enclosed treehole, last dispenser is complete, with yellow mud, treehole is sealed completely.
