Abstract

The invention relates to a botanical antiseptic pesticide prepared by the following materials: 6-8% by weight of sulphur, 3.5-5.5% by weight of rosin, 2.5-4.5% by weight of sodium carbonate, 4-6% by weight of calcium oxide and the balance of water and tar. The pesticide is prepared by the following steps: grinding sulphur, rosin, sodium carbonate and calcium oxide to powder; adding powder into reaction kettle in proportion and then mixing evenly under the temperature of 60-80 DEG C; adding water or tar in proportion and mixing; filtering medical solution with water obtained from step c; finally bottling filtered solution or medical solution with tar. The invention has the advantages of good plant-pathogen prevention effect and long controlling period.

Description

Bactericide

Technical field

The present invention's step and a kind of agricultural chemicals, particularly a kind of bactericide.

Background technology

Agricultural chemicals has a lot of kinds, and its protection crop growth has played important function.But some damage by disease and insect that are difficult to prevent and treat still have a strong impact on the output and the quality of agriculture and forestry product, improve constantly the important topic that the pesticide sterilizing effect is still people's research.

Summary of the invention

The purpose of this invention is to provide a kind of bactericide, this bactericidal agent for preventing and treating phytopathogen is effective, and the preventive effect phase is long.

Technical scheme of the present invention is: a kind of bactericide is characterized in that: made by following weight ratio raw material:

Sulphur 6-8%, rosin 3.5-5.5%, sodium carbonate 2.5-4.5%, calcium oxide 4-6%, all the other are water or tar.

Be preferably:

Sulphur 7%; Rosin 4.5%, sodium carbonate 3.5%, calcium oxide 5%, all the other are water or tar.

The preparation method of this bactericide may further comprise the steps:

A), sulphur, rosin, sodium carbonate, calcium oxide are ground into powder respectively;

B), in proportion powder is added respectively in the reactor, temperature 60-80 ℃, stir;

C), in proportion add water or add tar, stirred 10-15 minute;

D), the water liquid that adds among the step c is filtered;

E), with filtered fluid or add tar soup bottling.

Add the bactericide that water makes and be called No. 1, contain the bactericide that tar makes and be called No. 2.Present technique is applicable to fruit tree, crops sterilization.No. 1 the bactericide using method is: at first bactericide is diluted with water to spray liquid, dilution ratio is 1: 150-300, be sprayed in the soil of plant growing, and sprayed once again in 10-15 days, if rained in 2 hours behind the spray medicine, fill spray.No. 2 the bactericide using method is: medicament is applied in the trunk affected part, smears evenly, be coated with once in 7-15 days again, also can only be coated with 1 time according to the effect situation.Also can mix use in 1: 1 ratio with machine oil or lead oil.

The present invention has special efficacy to the disease sterilization of crops such as apple tree, paddy rice, vegetables, and the preventive effect phase is long.

Sterilizing mechanisms of the present invention is: the sulphur among the we, sodium carbonate (popular name soda ash), calcium oxide (popular name quicklime) has strong impulse and corrosivity to germ, causes in germ table physical efficiency and burns, festers.They are mixed with mixture, and brush can protect trees by desinsection on trunk, makes germ dead about 3-5 days.Execute in soil and can kill underground germ, again can neutralizing acid alkalescence, keep the nutrient in the soil normally to play a role, promote plant metabolism.Rosin has insecticidal action, can protect trees, and prevents the sick scar major criminal of trees.Tar has adhesivity, can prevent drug wastage.This bactericide is in soil, and the insect pest performance bactericidal action to the children gives birth to the phase has prevented that effectively the growth of insect pest from overflowing.And in soil, be difficult for running off, long action time, to the intractable germ, easily the germ of recurrence has killing effect preferably.

Indoor to make test report as follows in this institute in the present invention:

Test medicine: No. 2 bactericides

Suppress object: the apple rot pathogen mycelia

Assay method: on superclean bench, test medicine is made into the soup medium plane of different multiples, every kind of each 4 reprocessing (4 ware) of concentration, and establish the blank of not dosing.After treating that the medium plane is solidified, inoculation apple rot pathogen monospore pure culture, 3.5 millimeters of bacterium cake diameters are put 1 bacterium cake in the middle of every ware, cultivate 2.5 days in 26 ℃ of insulating boxs, measure each ware mycelia diameter in length and breadth, average, deduct 3.5 millimeters mycelia cake diameters again, be mycelial growth and deposit diameter, compare with blank, ask different soup bacteriostasis rates (%).

Bacteriostasis rate is measured table

The liquor strength ratio	1∶130	1∶150	1∶170	1∶300	Blank
						The mycelial growth diameter	4.0	6.5	17.5	22.3	40.3
Inhibiting rate (%)	90.07	83.87	56.58	44.67	-----

Find out according to measurement result: liquor strength 1: 130, inhibiting rate (%) 90.07, liquor strength is high more, and it is good more to suppress effect.

Result of use of the present invention:

2005, in Xingcheng City hot spring apple orchard, Liaoning Province, use bactericide of the present invention, prevent and treat apple valsa canker.April then is coated with soup 2 times after controlling scraping on the disaster-stricken apple tree, surpasses sick scar edge 2cm during coating, falls ill the 2nd year spring and carries out efficacy survey April Sheng phase, efficient the reaching more than 90% of statistics control.

The 7-8 month in 2000, false smut takes place in the paddy rice in prosperity village, Changyi District Jiu Zhan township, Jilin, uses No. 1, this medicine (stoste), and false smut was controlled in 6-10 days, sprays again after 10 days and once consolidates effect, and control efficiency reaches more than 88%.

In August calendar year 2001, three estrade villages, Jilin Jiu Zhan township, one society two green peppers are arranged transplants seedlings and sprayed this medicine No. 1 in preceding 3 days, and the growth of green pepper seedling is normal, does not have insect pest, and on the green pepper ground that does not prevent the plague of insects with the village large stretch of dead seedling sprout has taken place.

Embodiment 1

Prepare 100 kilograms of No. 1, bactericides (aqua), take by weighing 7 kilograms in sulphur, 4.5 kilograms of rosin, 3.5 kilograms of sodium carbonates, 5 kilograms in calcium oxide, 80 kilograms in water.At first sulphur, rosin, sodium carbonate, calcium oxide are ground into powder respectively, 90 orders, the powder with each raw material adds in the reactor respectively then, stirring mixes it, in the reactor temperature 60-80 ℃, adds water, stir and made slurries in 10-15 minute, filter the clarification bottling.Using method is: at first with bactericide dilute with water again, make spray liquid in 1: 150 ratio, spray liquid is sprayed in the soil of plant growing, spray is once again for medication 10 days.

Embodiment 2

Prepare 100 kilograms of bactericides (finish), take by weighing 76 kilograms in 8 kilograms in sulphur, 5.5 kilograms of rosin, 4.5 kilograms of sodium carbonates, 6 kilograms in calcium oxide and tar.At first sulphur, rosin, sodium carbonate, calcium oxide are ground into powder respectively, the powder with each raw material adds respectively in the reactor then, heats to 60-80 ℃, after stirring mixes it, adds tar, stirs and makes finish, bottling.Using method is: this product is applied in the affected part, smears evenly, be coated with 1-2 time both can, also can mix use in 1: 1 ratio with machine oil or lead oil.
