Abstract
The present invention provides a compound basic copper sulfate tobacco leaf germicide and a preparation method thereof, which relates to a composition type plant germicide, wherein the germicide is prepared from copper sulfate, zinc sulfate, calcium hydroxide and potassium sulfate or potassium dihydrogen phosphate. The germicide of the present invention has favorable effect on preventing and controlling angular leaf spots, stem blight, anthracnose, target spots, downy mildew, dark brown spots, rust diseases and other fungus and bacterial diseases of tobacco, paddy rice, fruit trees, vegetables and other crops, and has the functions of regulating the growth of crops and killing aphids, mites and other pests. In the present invention, the preparation method is simple, and the germicide has the advantages of low cost, low toxicity to people and livestock, and safe and convenient use and has good popularization value and good market prospects.
Description
The present invention relates to composite type plant bactericide and manufacture method thereof, specifically is a kind of bactericide that contains inorganic compound, is specially adapted to the control of the multiple fungal disease in tobacco leaf vegetative period.
Existing tobacco leaf fungal disease control medicament mostly is organic compound class agricultural chemicals, as control in field thiophanate methyl (Ishii, K. commonly used, Abstr.7th Int.Congr.Pl. prot., paris, 1970, P.200), it has bactericidal activity and interior absorption preferably, still, and the production method complexity of this medicine, used Organic Ingredients price is expensive, the cost height, residual quantity is bigger, and is harmful to people and animals.Usually adopt the bactericide of copper sulphate preparation, in sterilization, often to doing deposits yields damage to a certain degree, seem particularly outstanding vegetative period at tobacco leaf again, this is a urgent problem in the tobacco leaf cultivation process.
The purpose of this invention is to provide a kind of raw material and be easy to get, with low cost, tobacco leaf multiple diseases in vegetative period is had good control efficiency, also have the bactericidal composition of regulating tobacco leaf growth effect simultaneously.
The object of the present invention is achieved like this: this bactericidal composition contains copper sulphate, zinc sulphate, slaked lime and can regulate the potassium sulphate or the potassium dihydrogen phosphate of tobacco leaf growth, wherein the effective dose percentage (weight %) of each component is copper sulphate 30～40, zinc sulphate 4～10, slaked lime 50～60, potassium sulphate or potassium dihydrogen phosphate 1～5.
Bactericidal composition of the present invention, wherein the effective dose percentage (weight %) of each component can be copper sulphate 35, zinc sulphate 6, slaked lime 56, potassium sulphate or potassium dihydrogen phosphate 3.
The present invention can adopt following method to be prepared:
1. with copper sulphate be raw material, levigate, cross 200 mesh sieves; Again that zinc sulphate is levigate, cross 200 mesh sieves, weighing charging respectively, add potassium sulphate or the potassium dihydrogen phosphate that to regulate the tobacco leaf growth then, the effective dose percentage (weight %) of each component is during preparation: copper sulphate 30～40, zinc sulphate 4～10, slaked lime 50～60, potassium sulphate or potassium dihydrogen phosphate 1～5 are with the pulvis pack of gained;
Calcium oxide is levigate 2., cross 250 mesh sieves, with the pulvis pack of gained;
3. will above-mentioned two kinds of pulvis when using by calcium oxide: the ratio mixing of copper sulphate=2: 1 (weight ratio), per 0.56～0.76 kilogram intermixture is converted 100 kilograms in water, stirs afterwards, promptly makes compound basic copper sulfate sterilization suspension.
The present invention compared with prior art has the following advantages:
1. with low cost, raw material extensively is easy to get;
2. the technological process of production is simplified, and method of manufacture and use thereof is all very simple;
3. the present invention uses the ensuing crop residual quantity low, to people and animals' low toxicity.
4. the present invention is through small plot experiment, effect experiment, large area control comparative experiments, toxicity and residual hazard physico-chemical analysis, great number tested data shows, the present invention has good control efficiency to fungies such as the angular leaf spot of crops such as tobacco, paddy rice, fruit tree and vegetables, stem wilt, anthracnose, zonate spot, downy mildew, dark brown pinta, rust and bacterial disease, also has the effect of regulating plant growth simultaneously, and the insects such as aphid, mite extremely of holding concurrently, have excellent popularization and be worth and market prospects.
By national plant protection unit required standard, calculate with the incidence of disease, disease index, percent of loss; Pilot survey data of the present invention are as follows: (seeing the literary composition back)
Embodiment 1:
The configuration proportion of bactericide (weight %) is: copper sulphate 30, and zinc sulphate 9, slaked lime 60, trace meter salt 1,
The preparation method of this bactericide is:
1. with copper sulphate be raw material, levigate, cross 200 mesh sieves, add the trace meter salt of coordinate plant growth then, with the pulvis pack of gained;
Calcium oxide is levigate 2., cross 250 mesh sieves, with the pulvis pack of gained;
3. will two kinds of above-mentioned pulvis when using in calcium oxide: after the ratio mixing of copper sulphate=2: 1 (weight ratio), per 0.56 kilogram intermixture are converted 100 kilograms in water and stirred, promptly make compound basic copper sulfate sterilization suspension.
Embodiment 2:
The configuration proportion of bactericide (weight %) is: copper sulphate 35, and zinc sulphate 6, slaked lime 56, potassium sulphate or potassium dihydrogen phosphate 3,
The preparation method of this bactericide is:
1. with copper sulphate be raw material, levigate, cross 200 mesh sieves, add the trace meter salt of coordinate plant growth then, with the pulvis pack of gained;
Calcium oxide is levigate 2., cross 250 mesh sieves, with the pulvis pack of gained;
3. will two kinds of above-mentioned pulvis when using in calcium oxide: after the ratio mixing of copper sulphate=2: 1 (weight ratio), per 0.6 kilogram intermixture are converted 100 kilograms in water and stirred, promptly make compound basic copper sulfate sterilization suspension.
