Abstract

The present invention belongs to a germicide, particularly to a compounded Cu-Al germicide which is especially suitable for preventing and controlling pest and disease damage of vegetables. The germicide is prepared from succinic acid copper, efosite-Al, metalaxyl and pottery clay auxiliary agents containing nekal powder, or gleditsiae powder, peregal powder and white carbon black powder by the conventional method. The present invention has especially good effect on preventing and controlling cucumber bacterial angular leaf spot, black spot of Chinese cabbages and spot blight of wildcelery herbs and has the function of treating downy mildew of cucurbits, etc. The present invention is a compounded germicide with high efficiency, broad spectrum and low toxicity.

Description

Compounded Cu-Al germicide

The invention belongs to bactericide, is a kind of compounded Cu-Al germicide that is specially adapted to prevent and treat the vegetables damage by disease and insect.

The Recompounded pesticide that has been used at present to prevent and treat crops bacterial angular leaf spot, powdery mildew and white viral diseases such as cucumber, Chinese cabbage has auspicious malicious copper (being made by metalaxyl, copper sulphate and additive compound) and DTMZ(to be mixed with by succinic acid copper, aliette and auxiliary agent) and since be subjected to bactericide component in the preparation reached influence that adhesion, interior suction and suspension effect auxiliary agent match exist the interior suction time short, drug effect is low and deficiency such as broad spectrum activity difference.As its preventive effect of soup that contains auspicious malicious copper only is 75-77%, DTMZ only is 75-78% to cucumber and white viral disease preventive effect, is suction time and the suspension of drug powder in soup in the neutral detergent etc. that play adhesion, suspension effect in the 75-80% auxiliary agent also affect to the preventive effect of angular leaf spot.

The object of the present invention is to provide a kind of serves as main composite bactericide of holding concurrently anti-powdery mildew and white viral disease to prevent and treat angular leaf spot.The material that plays adhesion, suspension effect in closing reason apolegamy agricultural chemicals component and the auxiliary agent improves the preventive effect and the broad spectrum activity of compound drug, to overcome the existing in prior technology deficiency.

The present invention is a compounded Cu-Al germicide, and it is mixed after by pulverizing such as succinic acid copper, aliette, metalaxyl and potter's clay auxiliary agents and makes.Wherein succinic acid copper is that 20-25%, aliette are that 4-8%, metalaxyl are 1-5%, and surplus is an auxiliary agent, auxiliary agent be contain effective dose draw back powder or spaonin powder, neutral detergent or peregal powder, the potter's clay of white carbon powder; Its compounding method is that succinic acid copper, aliette, metalaxyl, auxiliary agent are dried processing respectively, putting into agitator after mixing according to the above ratio mixed 10-15 minute, it is sent in the cracker, the composite bactericide powder after pulverization process should have 90-98% to pass through 200 order screens again.

The content that draws back powder or spaonin powder in the potter's clay auxiliary agent of this composite bactericide is 2-8%, and the content of neutral detergent or peregal powder is 2-6%, and the content of white carbon powder is 4-8%.

Each main content of medicines of 25-28% compounded Cu-Al germicide is respectively: succinic acid copper accounts for 20-21%, and aliette accounts for 4-6%, and metalaxyl accounts for 1-1.5%, adds peregal powder, spaonin powder in the potter's clay.

Its soup is respectively to get 25-28% compounded Cu-Al pulvis to be blended into its total amount respectively be 300-400 water doubly, 500-600 water doubly, and 800-1000 water doubly is mixed with soup.

Accompanying drawing of the present invention is the preparation flow block diagram of compounded Cu-Al germicide.

Embodiments of the invention are that granularity is 200 purpose wettables, 25% compounded Cu-Al pulvis, wherein succinic acid copper content is about 20%, and aliette content is about 4%, and metalaxyl content is about 1%, the peregal powder that contains 2-6% in the potter's clay auxiliary agent, the white carbon powder of the spaonin powder of 2-8% and 4-8%.

1, the every strain of the medicament of 300 times of liquid of concentration is irritated root for half jin, can be used for preventing and treating watermelon blight.

2, concentration is 500-600 times of liquid medicament, cucumber, celery, tomato etc. is carried out foliar spray can be used for preventing and treating bacterial angular leaf spot, celery septoria disease and late blight.

3, concentration is that 1000 times of liquid medicaments carry out foliar spray to Chinese cabbage, can prevent and treat Chinese cabbage middle and later periods black spot.

In addition, 800-1000 times of liquid medicament carries out blade face fruit spraying to fruit tree and can play the sterilization fresh-keeping effect.

The substantive distinguishing features that the present invention has and the technological progress that obtains are:

1, because the effective ingredient of this compound drug is metalaxyl, second Phosphorus aluminium and butanedioic acid copper have special efficacy to control cucumber bacterial angular leaf spot, cabbage alternaria, celery septoria disease, and preventive effect can reach respectively 85-90%, more than 90%.

2, account for interpolation peregal powder at auxiliary agent and replace neutral detergent; and powder is pulled open in interpolation or the Chinese honey locust powder can improve the adhesive attraction of this medicine liquor and improve the suspension of medicine end in liquid; increased the residence time after the dispenser (being about 15-30 days); make this composite drug combine the advantage of protective agent and systemics; make it have higher preventive effect, also remedied the deficiencies such as single dose broad spectrum activity difference simultaneously.

3, this compound drug property of medicine safety is very low to the toxicity to man and livestock effect during use, and the actual measurement LD50 that calculates 25% auspicious aluminum bronze composite bactericide according to the Finney formula is 0.48 less than 0.5, so mixture toxicity is antagonism.

This medicine is blue, green pulvis, and it is better to be slightly soluble in the water humidity resistance, has the low medicine source of cost and extensively is convenient to the distinguishing features such as storage, transportation and use.
