Summary of the invention
If parasitic pest on the trees, then since the influence of the toxin that food evil or pest generate etc. hinder the growth of trees, or cause trees withered.For this problem, the countermeasure of always taking is perhaps medicament to be injected trunk and handle, perhaps in order to prevent the expansion of devastated, burn part or all and confirmed the trees of insect parasitic, still be in the state of also not finding more effective countermeasure so far.In addition, people also wish have pair trees not have the method for preventing and treating of medicine infringement always.
The object of the present invention is to provide a kind ofly, trees are not produced hazards of medication, but and with low dose high efficiency just, the method that can also promptly prevent and treat pest parasitic on the trees simultaneously.
Present inventors have carried out deep research in order to solve above-mentioned problem, found that by using specific active ingredient can reach desired purpose, thereby have finished the present invention.
Promptly; the present invention relates to contain the composition for preventing and controlling tree parasitic pest for tree (hereinafter to be referred as composition) of Thiophosphonate imicyafos as active ingredient; use the preventing and controlling tree parasitic pest for tree method (hereinafter to be referred as method) of Thiophosphonate imicyafos, and use the guard method (hereinafter to be referred as guard method) of Thiophosphonate imicyafos as the trees of active ingredient as active ingredient.
Have optical isomer among the Thiophosphonate imicyafos, be used for Thiophosphonate imicyafos of the present invention and comprise various isomer, and isomer mixture both.
Embodiment
Do not have special qualification for trees, for example can enumerate as object of protection, as pine tree, Chinese fir, cypress, fagus, the forest of Oak Tree etc.; As oranges and tangerines, apple, pears, fig, persimmon, peach, grape, chestnut, cherry, plum (plum), damson (Prunes), loquat ， Zhu Sou, the fruit tree of plum etc.; As cuckoo, azalea, camellia, camellia, the rose of Sharon, oriental cherry, sweet osmanthus, landscape tree of maple etc. or the like wherein can be prevented and treated the pest that colonizes on the forest effectively, particularly can prevent and treat the pest that colonizes on the pine tree effectively.And, as the pine tree of object of protection, be not limited only to the pine tree in the mountain forest, also comprise the park, garden, pine forest, the pine tree of various different places such as golf course.
As the pest that becomes controlling object, for example can enumerate the nematoda that the growth of trees is produced baneful influence as pine wood nematode etc.; Sky bovine as Monochamus alternatus (Monochamus alternatus.) etc., as bark beetle (bark beetles) class of blastophagus minor (Tomicus minor) etc., resemble the brill sky insect of getting food among the intrusion trees such as curculionid (weevils) class of (Shirahoshizo insidiosus) etc. as Xiao Song angle shin; As the big aphid of pine, the Phytophthira of adelge laricis etc., shell insects, the sucking insect of lecanium class etc.; Spider mite kind as pine needle mite etc.; As loose gallfly, the fly class of China fir gallfly etc.; As leaf rollers, the geometrid moth class, the psychid class, the caterpillar class, the heart-eating worm class, sawfly class etc. get feeding habits insect etc.Wherein for nematoda, the control of boring property insect is very effective, and especially for pine wood nematode, the control of Monochamus alternatus is very effective.
Because composition of the present invention can doublely be controlled nematoda and boring property insect, therefore can protect trees extremely effectively and not be subjected to the harm of pest.For example, withered problem takes place in the trunk about pine tree, main cause is a parasitic pine wood nematode on the pine tree, thereby cause the physically different of pine tree, therefore think if pine wood nematode is prevented and treated, just can prevent and treat the withered of pine tree, but, pine wood nematode and Monochamus alternatus are symbiosis, because Monochamus alternatus is by being media with the pine wood nematode, therefore the expanded range that it is parasitic only prevents and treats the pine wood nematode of causing the withered main cause of pine tree to very wide scope, can not tackle the problem at its root.Therefore, both can get rid of main cause (for example preventing and treating pine wood nematode) as the withered obstruction arboreal growth that waits of pine tree, the composition of the present invention that can get rid of secondary reason (for example also preventing and treating Monochamus alternatus) again as the media worm, under usage amount situation seldom, also can obtain the effect of wide model, therefore composition of the present invention is very useful and practical.
For the processing method of composition of the present invention, there is not special qualification, for example can enumerate: set body and inject processing, soil treatment under the tree crown, cauline leaf is handled, coating processing etc.Inject as above-mentioned tree body and to handle, for example can enumerate: the method for in the trunks of trees or root system, handling etc.As soil treatment under the tree crown, for example can enumerate: use the spreading liquid of the various preparations that thinner such as water suitably dilutes or the method that aqueous preparation itself is handled soil, use solid pharmaceutical preparation processing soil surface itself or soil excavated the method for handling about several centimetres (cm).In the above-mentioned processing method, soil treatment under the preferred tree crown wherein more preferably uses the spreading liquid or the aqueous preparation itself of the various preparations that thinner such as water suitably dilutes, perfusion to handle soil-perfusion processing under the tree crown of soil.Can use sprayer to handle during processing, also can handle by manual.The soil-perfusion processing is the processing method with various advantages under the tree crown, for example can enumerate as above-mentioned advantage: 1) be not need special expertise, only soup be filled into the easy processing method that gets final product in the trees soil on every side; 2) to processing period of medicament without limits; 3) inject processing with the industry at the more trunk of commercial enforcement and compare, the operating time that is spent on 1 trees is shorter; 4) not needing to carry out trunk injects the bottle of handling after the necessary processing and reclaims; 5) do not need to carry out trunk and inject the necessary perforate on trunk of processing, therefore neither can damage the outward appearance of trees, can be because of causing rotting of trees or resistance reduction etc. from medicament hand-hole invader or wind and snow yet.
Composition of the present invention, owing in trees, permeate transfer as the Thiophosphonate imicyafos of active ingredient, so can obtain desired effect by Local treatment.By soil treatment under the aforesaid tree crown, more preferably soil-perfusion is handled under the tree crown, thereby makes the Thiophosphonate imicyafos as active ingredient obtain desired effect to the trunk penetration transfer from root, and therefore above-mentioned processing is particularly useful.
For example, aforesaid pine wood nematode or, the trees inside in pine tree of Monochamus alternatus etc., more particularly in trees inside, the pest of branch inside and/or root parasitism by carrying out Local treatment as the use of soil treatment under tree crown composition of the present invention, can prevent and treat.
In addition, composition of the present invention can also obtain prevention and treat ambilateral effect, promptly, trees be injured take place before or the existence of parasitic pest period arbitrarily before being identified, thereby trees are handled the method that obtains desired effect, with be injured trees take place after or parasitic pest exist and be identified period arbitrarily afterwards, thereby trees are handled the method that obtains desired effect, above-mentioned two kinds of methods can adopt.
Processing about the present composition; though kind and size according to the trees that constitute object of protection; constitute kind or the situation occurred of the pest of controlling object; further also will be according to the condition of meteorology or soil; processing period, the difference of preparation form etc. and can not without exception stipulating, but making the concentration of Thiophosphonate imicyafos in trees as active ingredient usually is 0.1～100ppm; be preferably 0.5～50ppm, more preferably 0.5～10ppm handles.Treating capacity about the present composition, for example, if near breastheight footpath (ground height is about 1m) is the trees about 10cm, so with respect to the one tree wood of such size, Thiophosphonate imicyafos treating capacity is 5～2000g, is preferably about 20～1000g.But only concentration of treatment or treating capacity can be with reference to above-mentioned various conditions etc., suitably carry out preliminary experiment etc. and indivedual decision.For example; composition of the present invention has higher safety to trees; therefore according to kind and the size of the trees that constitute object of protection; constitute kind and the situation occurred of the pest of controlling object, the condition of meteorology or soil, processing period; the various conditions of preparation form etc.; treating capacity that can more slightly setting present compositions as a specific example, can use near the amount the upper limit of above-mentioned treating capacity to handle.Processing also has the advantage that can keep pharmacy effect for a long time like this.On the other hand, composition of the present invention can hang down dose and prevent and treat the pest that colonizes on the trees expeditiously, therefore according to aforesaid various conditions, can be more less set the treating capacity of the present compositions, as a specific example, can use near the amount of lower limit of above-mentioned treating capacity to handle, for example if breastheight directly is the trees about 10cm, so with respect to one of such size trees, can use 5～400g, the Thiophosphonate imicyafos of preferred 20～100g scope handles.
