Description

A kind of Fungicidal insecticidal composition

The invention belongs to pesticide field, specially refer to the prescription and the using method of the Fungicidal insecticidal composition of control fruit tree diseases and pests.

The generation of damage by disease and insect is having a strong impact on agricultural production, the damage by disease and insect of ten thousand in fruit tree especially, and harmfulness is very big, and control is got up and suitable difficulty.Fruit tree putrefaction disease still is a kind of destructive disease now, and two spotted spider mite and aphid then are the main insect pests of harm fruit tree, in order to control the generation of damage by disease and insect, annual all necessary a large amount of manpower and financial resources that drops into.Many agricultural chemicals and plant protection expert have also successively proposed many formulation of pesticides and comprehensive processing method, and the control damage by disease and insect has been played suitable effect.But various prescriptions also cut both ways, and the prevention target that wants to reach desirable also has very big difficulty.

At the problem of control fruit tree putrefaction disease, the inventor once proposed the prescription of a kind of " multipurpose MIEFULING for eliminating saprophytic bacteria ", and had applied for patent of invention in 1990 to Patent Office of the People's Republic of China, and application number is 90105393.7.

" multipurpose MIEFULING for eliminating saprophytic bacteria " is to be main sterilization component with asomate, add the pesticidal preparations of relevant auxiliary agent processing, remarkable to control diseases of branches of fruit trees effect, since going into operation, welcome by numerous orchard workers, except that Shandong Province's extensive use, in Hebei, fruit producing region such as Liaoning, Shanxi, Henan, also obtained large-area applying.Facts have proved, this medicament is the good eradicant of diseases of branches of fruit trees, but 2 deficiencies in application process, have also been found, the one, to the insect pest of fruit tree without any kill capability, anti-after being ill, also must select other insecticides that is fit to again for use, and the reorganization manpower and materials are carried out the desinsection processing with this medicament, formality is loaded down with trivial details, and is time-consuming; The 2nd, this medicine is higher at working concentration, when particularly extension rate is lower than 50 times, might produce poisoning to treelet.

For remedying above-mentioned deficiency, be necessary to develop a kind of through single treatment, can root out the survive the winter bacterium source of tree on the body, can root out the worm source of surviving the winter on the tree body again simultaneously, and have higher bactericidal activity and the lower poisoning and the novel agrochemical compound formulation of toxicity.The inventor is on the basis of large tracts of land field practice for many years, the prescription of " multipurpose MIEFULING for eliminating saprophytic bacteria " is adjusted and is improved, proposed a kind of novel Fungicidal insecticidal composition--the prescription of multi-effect compound Miefuling has also been determined optimum and rational using method.

Fungicidal insecticidal composition composition of the present invention and prescription are as follows:

Composition percentage by weight (%) 40% asomate wetting powder 68-80 Cosan 6.8-18 zinc sulphate 4-4.5 borax 2.2-2.7 wetting and penetrating agent 6.5-7.5 callus promoter 3-5ppm.

Introducing Cosan in prescription is one of principal character of the present invention.

Cosan is a kind of known insecticidal/acaricidal agent, and is quite effective to the control two spotted spider mite, and in this prescription, its action function mainly is to root out the worm source of surviving the winter on the tree body.Use Fungicidal insecticidal composition of the present invention, only need the tree body is carried out single treatment, can root out the bacterium source and the worm source of surviving the winter simultaneously; On the other hand, sulphur also has great bactericidal action, particularly in this prescription, in a ratio range that suits, the adding of sulphur has been played obvious synergistic effect (specifically seeing inhibition zone test comparison data among the embodiment for details) to the sterilizing ability of asomate, thereby has improved the overall sterilizing function of Fungicidal insecticidal composition of the present invention, helps improving the extension rate in the use, avoid the generation of poisoning, the toxicity of preparation itself also decreases simultaneously.

Practice shows that the usage ratio (weight ratio, as follows) between 40% asomate wetting powder and the Cosan in the prescription (folding 100%) should be controlled at 100: within the scope (8.5-26.5).When this usage ratio is 100: the highest in the time of (16-17) to the synergistic effect of sterilizing function, but consider the resultant effect of sterilization and desinsection, the optimum range of this usage ratio should be 100: (15-25), in this scope, sterilization and insecticidal effect are all more satisfactory.

Wetting and penetrating agent described in the Fungicidal insecticidal composition prescription of the present invention is generally selected common drug peregal or other suitable surfactant-based medicaments for use; Callus promoter described in this prescription is generally selected methyl or the gibberellin or the basic element of cell division for use.

The preparation method of this Fungicidal insecticidal composition continues to use the processing method of general wetting powder substantially, after being about to sulphur and pulverizing airing, gets final product by the requirement of the percentage of filling a prescription and 40% asomate wetting powder and other auxiliary agent mixing and stirring.

The using method of Fungicidal insecticidal composition of the present invention is an another principal character of the present invention.

The control of fruit tree diseases and pests is a comprehensive science, has only good medicament, and unsuitable rational using method can not reach desirable control efficiency.The inventor inquires into according to a large amount of practices, has determined the best using method of Fungicidal insecticidal composition of the present invention.Now be described below:

For old tree or the grave illness orchard of making, need medication successively three times, generally before germination, carry out the medication first time, this moment is no matter have or not scab on the tree body, all should strike off coarse bark without exception earlier, then with dilution 100-120 soup spray limb doubly, till all evenly moistening.After one week, dispenser for the second time, with 50 times of dilute liquid medicines, with the even brushing trunk of hairbrush libation at an ancient wedding ceremony medicine, branches of tall trees bottom, big cut, saw kerf position and the scab place is arranged; Be separated by and go up brushing one time after a week for another example; Before coating, should use scraper vertically to delineate processing to scab, cutter carries out coating then apart from being 0.5 centimeter, helps improving drug effect like this.

For the hypopathia orchard or scurf is only arranged, the children of dry rot makes fruit tree, can spray one time with 100 times of dilute liquid medicines in the fallen leaves back, sprays one time with 100-120 times of dilute liquid medicine before the germination again, can reach satisfied preventive effect.Only limit to fruit tree for sick portion, can change into and carry out the brushing of disease portion with the 50-80 dilute liquid medicine and get final product at thicker limb position.The season of growth can only brush, and can not spray, and drug concentration can be grasped in the scope of 80-100 times of dilute liquid medicine.

Use Fungicidal insecticidal composition of the present invention and, can play the double simultaneously effect of controlling of disease and insect pest according to above-mentioned using method proper application, saving of work and time, a dispenser is got twice the result with half the effort.Obviously be better than " multipurpose MIEFULING for eliminating saprophytic bacteria " in the effect of rooting out bacterium source side face the present invention prescriptions such as rot, dry rot, scurf, powdery mildew, produce poisoning hardly, even do not see that in production medication in season poisoning takes place yet, aspect pest control, it can effectively root out the worm sources of surviving the winter on limb such as two spotted spider mite, aphid, scale insect, the generation and the harm of control insect pest.This medicine is not only applicable to the rooting out of wintering pest source of fruit trees such as apple, pears, peach, apricot, hawthorn, Chinese chestnut, pomegranate, cherry, plum, is applicable to the control of the damage by disease and insect of mulberry, paulownia etc. simultaneously yet.

Below, be example with three prescriptions, introduce the indoor bacteria inhibition assay of Fungicidal insecticidal composition of the present invention and field control damage by disease and insect effect and with the correction data of " multipurpose MIEFULING for eliminating saprophytic bacteria ".
