Abstract

The invention discloses a pesticide applying method for preventing tree pests. The pesticide applying method comprises the following steps that (1) an annular ditch is dug around a tree, and the depth of the ditch cannot damage a root system; (2) pesticide is prepared, corresponding drugs are selected according to the types of insect pests needing to be prevented, the number of the drugs is determined generally according to the size of the chest diameter of the tree, and 1-2 g of drugs in every centimeter of the chest diameter are diluted by clear water for standby application according to the proportion of 1: 100; (3) pesticide is applied, the diluted liquid medicine is poured into the annular ditch according to the size of the tree diameter; (4) the tree ditch with the pesticide being applied is watered; (5) the ditch is filled with soil and compacted, and after water in the ditch is dried in the shade, soil which is dug out when the ditch is dug is backfilled into the ditch, compacted and flattened. The pesticide applying method has the remarkable advantages that pesticide application is not limited by weather conditions, the insecticidal efficacy is good, the lasting period is long, the utilization rate of drugs is high, the insecticidal range is wide, and the pollution is not polluted.

Description

A kind of application method of preventing and treating trees insect

Technical field:

The present invention relates to a kind of plant pest management technology, particularly a kind of application method of preventing and treating trees insect.

Background technology:

Due to impacts such as wind-engaging, rain, illumination decomposition in the trees extermination of disease and insect pest, conventional spray method, the utilizing status of medicine is poor, and in addition, conventional spray method is very poor for the control efficiency being not easy the insect monoid being sprayed onto or effectively can not contacting with insect generation.

Summary of the invention:

The object of the invention is to provide a kind of good disinsection effect, and drug utilization is effective and do not limit and environment amenable a kind of application method of preventing and treating trees insect by dispenser condition.

The technical scheme realizing the object of the invention is, a kind of application method of preventing and treating trees insect, is characterized in that there is following step:

(1) around trees, dig annular ditch, the degree of depth of ditch is advisable not injure root system,

(2) make up a prescription, choose corresponding medicine according to the kind of wanted pest control, the selection of dose, generally determine with the size of tree breast-height diameter, 1:100 clear water pressed by every cm diameter of a cross-section of a tree trunk 1.3 meters above the ground 1-2 gram medicine, and drug dilution is for subsequent use;

(3) dispenser, enters in annular ditch by the liquid of above-mentioned dilution by the large young pathbreaker's medicine liquid irrigation of tree-walk;

(4) water, the tree ditch of dispenser watered,

(5) fill compaction, after the water in ditch dries in the shade, by the earthen backfill of digging out during ditching in ditch and to carry out compacting smooth.

The present invention has dispenser compared with the prior art by weather condition restriction, good disinsection effect, the lasting period is long, utilization ratio of drug is high, insecticidal range is wide and free from environmental pollution remarkable advantage.

Embodiment:

The present invention has following embodiment, and in order to obtain the effect of better pest control, spraying time generally dispenser in 7-10 days before insect time of origin, has following steps:

(1) dig pit, the ground around trees ' root dug the ditch of annular, the degree of depth of ditch not injure tree root for principle, the width 20-30cm of ditch, the mound dug out is outer for subsequent use at ditch;

(2) make up a prescription, the insect according to control chooses corresponding medicine, and such as, a, the anti-sucking pest such as to eliminate aphis can select 10% Acetamiprid soluble powder; The moth bar class pests such as b, control longicorn select 50% thiacloprid water dispersible granules; C, prevent and kill off the To Leaf-feeding Insects such as Lepidoptera and select 50% diafenthiuron missible oil; Choosing of dose, according to tree breast-height diameter, namely the diameter of trees trunk is determined, usual 1 gram/cm, and after pure water dilution, the ratio of dilution is 1:100;

(3) dispenser, to prepare above-mentioned and the liquid diluted pours in annular ditch;

(4) water, because the amount of the liquid of dilution is less, after administration, need water, irrigation amount generally should not make water overflow outside ditch, at high temperature season, and the cold water pouring as far as possible just need not extracted from underground;

(5) bury soil, after the water in annular ditch dries in the shade naturally, by earthen backfill during ditching, then slight compacting is implemented to backfill soil and clap.

Application method of the present invention has the following advantages:

1, drug utilization efficiency is high, duration is long, the ingenious conduction utilizing trees of root application technology, medicine is made to be distributed to the position such as leaf, stem, branch, flower, fruit of tree quickly and efficiently, medicine is not by the impact that wind and weather, illumination are decomposed, after in agricultural chemicals input tree body, then substantially avoid or reduce the above-mentioned effect being unfavorable for drug effect maintenance factor.The liquid availability of root application saves about 60 ~ 80% than conventional application method.Agricultural chemicals enters after in tree body, and scatter and disappear all few with loss, the duration is long, is generally valid up to 3 ~ 6 months.

2, the wide root application of insecticidal range not only can kill defoliator, for sucking pest, as scale insect, aphid, two spotted spider mite, and hiding pest is as Osier weevil, longicorn etc., conventional spray medicine is not easily sprayed onto or with insect, effective insect monoid contacted can not occurs and can play good control efficiency.

3, protection of the environment decreasing pollution.Root application relies on the transpiration of tree body, by drug delivery to site of action, and last natural decomposition.Avoid the contact with surrounding environment, decrease the direct contact to other animal and plant, can not become scattered about in air, to person poultry safety, do not kill and wound non-target animals and plants, can available protecting natural enemy.

4, use safety and spraying are compared with traditional application method such as to dust, and root application good operation conditions, operator does not directly contact medicine, effectively protects the personal safety of operator.

5, the control of insect not making the conventional method such as the top insect of tall and big trees and root-feeding insect, the disguised sap-sucking insect with the protection of wax shell, wood-boring pest and vascular bundle insect be difficult to effectively control by this method of restriction of trees height and hazardous distinguish etc. becomes simple.Tall and big forest, mountain forest with a varied topography, the method operating difficulties such as spraying, and root application technology is easily accomplished, compensate for the deficiency of traditional application method.

Claims (1)
