Lime Bordeaux liquid is an eco-friendly disinfectant that has been made and used by farmers in orchard-cultivation farms, such as lime sulphide, after Milardet, France, was found to be effective in grape grape disease in 1886. In addition, lime Bordeaux liquid is a cheap fungicide that can be widely used in fruits such as grapes, apples, pears, peaches, cereals such as rice, wheat, and barley, and vegetables such as potatoes, tomatoes, eggplant, peppers, cabbage, watermelon, spinach, and pumpkin.

Diluting lime bordeaux solution by diluting 40 ~ 50 times in water forms thin film on leaves and stems, and becomes copper salt in soluble state and contacts germs. The copper ions (Cu ⁺⁺ ) of this soluble copper salt are first adsorbed on the surface of the cells and some of them penetrate into the cells, replacing them with normal cations (M ⁺⁺ , K ⁺ , H ^+, etc.) bound to the cell membrane or intracellular proteins. do. As a result, the physiological action of the cells may be altered or combined with the SH group of the dehydratase in the cell to inhibit the physiological action of the bacteria, or the physiological action of the cell cells may be disturbed by excessive oxidation promotion in the cell by the ion. It causes sterilization. By this action, lime Bordeaux liquid can prevent the invading germs from the outside.

Conventional lime Bordeaux liquid is prepared by preparing two non-metallic barrels, adding copper sulfate (more than 98%) to 80% of the required amount of water, and making a diluted copper sulfate solution. After digestion, 20% water is added to make lime oil. Then, a small amount of copper sulfate is added to form Bordeaux liquid while vigorously shaking the cooled lime oil. Reaction schemes are _{8CuSO 4? 5H 2 O + 14CaO} → CuSO 4 · 7Cu (OH) 2 · 6Ca is takes on a blue color (OH) _2.

Lime Bordeaux liquid production method is divided into four heads (6), 6 heads, 8 heads depending on the amount of quicklime and water. Four heads of lime bordeaux solution is prepared with 450 g of copper sulfate and 225 g of quicklime with 80 liters of water. One is equivalent to 8 meals of lime.

Some crops are weak in copper (Cu) and weak in lime (Ca), so you should choose a suitable lime Bordeaux solution. For example, rice, barley, wheat, soybeans, cabbage, peaches, plums, persimmons, apples, pears, etc. are suitable for eight crops, while grapes, cucumbers, 4 heads of melon, potato, etc. are suitable, and the safe crop is 6 heads of grape, pear, citrus, tomato, eggplant, pepper, pumpkin, watermelon, melon, cucumber, green onion, onion, pea, spinach, cabbage. Suitable.

However, the conventional lime Bordeaux liquid is difficult to circulate for a long time to commercialize it by the copper sulfate particles are large, when the contact with the air is large, the drug effect is reduced. Even in good conditions without rainfall, drug efficacy is as short as about two weeks. In addition, the conventional lime Bordeaux liquid is precipitated by the copper sulfate particles become larger during storage, so that the solubility of copper is lowered, the drug efficacy is lowered.

In addition, when spraying before and after raining, but not attached to the crop well after spraying, the lime is washed down and copper is dissolved so badly occurs that there is a disadvantage that must be sprayed when the sunny day continues. In addition, the conventional lime Bordeaux liquid is precipitated by the copper sulfate particles become larger during storage, so that the solubility of copper is lowered, the drug efficacy is lowered. Therefore, the warranty period of the lime Bordeaux solution is generally used immediately after the manufacture, even if made with good raw materials and skilled techniques, there is a problem that the drug efficacy is lowered if used within a week.

In view of the above, the present inventors have completed the present invention in which zinc sulfate is contained in a predetermined ratio to reduce the weakness and increase the efficacy.

An object of the present invention comprises hydrated lime or lime carbonate and zinc sulfate and copper sulfate, and the mixing ratio of zinc sulfate and copper sulfate is 1: 5 to 1:10 to provide a zinc lime borated hydrate.

The present invention relates to a zinc lime borated hydrating agent consisting of hydrated lime or lime carbonate, copper sulfate and zinc sulfate, wherein the mixing ratio of zinc sulfate and copper sulfate is 1: 5 to 1:10.

Specifically, zinc lime bordeaux consisting of 10 to 60% by weight of hydrated lime or lime carbonate, 10 to 60% by weight of copper sulfate and 1 to 10% by weight of zinc sulfate and having a mixing ratio of zinc sulfate and copper sulfate of 1: 5 to 1:10. It relates to a hydrating agent.

Hereinafter, the configuration of the present invention will be described in detail.

In the present invention, hydrated lime (Ca (OH) ₂ ) or lime carbonate (CaCO ₃ ) is used among limes. This is caused by intense exothermic reaction when water is applied to quicklime (CaO). When copper sulfate (CuSO ₄ ) solution is added in this state of heat, the particles of Bordeaux solution become large and the suspension property is poor, so as to solve the problem. to be. Slaked lime or lime carbonate is 10 to 80%, preferably 20 to 50%.

Copper sulfate should be used with high purity (95% or more) to obtain a good product. The dosage is 10 to 60%, preferably 20 to 50%. If the content of copper sulfate is less than 10%, the sterilization effect is inferior, if more than 60% is weak.

Zinc sulfate is a high purity (90% or more) is used, the dosage is 1 to 10%, preferably 5 to 10%. If the ratio of zinc sulfate exceeds 10%, there is an uneconomical disadvantage.

The mixing ratio of zinc sulfate and copper sulfate is preferably 1: 5 to 1:10. If the ratio of zinc sulfate is lower than the above numerical value, the weakening effect is insignificant, and if it is higher than the above numerical value, adverse effects may occur.

All raw materials including lime, zinc sulfate and copper sulfate used in the present invention are characterized in that they are powdery. Compared to the case where the conventional lime bordeaux solution is diluted with 40 to 50 times water, the present invention can be diluted with 500 to 1000 times water.

The zinc lime borated hydrating agent of the present invention may be added with a dispersant to improve the colloidal state of the diluent. The dispersant is 1 to 20%, preferably 3 to 10%. If it is less than 1%, it will not be dispersed, and if it exceeds 20%, it will increase the cost.

In order to enhance the control effect of zinc lime bordeaux, a fourth type compound fertilizer or a microelement compound fertilizer may be added. In the present invention, the "fourth type compound fertilizer" is a total amount of two or more of the total nitrogen, water-soluble phosphoric acid or water-soluble potassium according to the fertilizer process standard according to the current fertilizer management law is 10% or more, the content of the guarantee component for each component is 1.0 It means fertilizer made to be more than%. In addition, in the present invention, "microelement compound fertilizer" means a fertilizer made by guaranteeing the water-soluble two or more components of boron, copper, iron, manganese, molybdenum and zinc in accordance with the fertilizer process standards according to the current fertilizer management law. .

The zinc lime borated hydrate of the present invention can be obtained by adding all raw materials including powdered lime, zinc sulfate and copper sulfate in the above numerical ranges and ratios, pulverizing and homogeneously mixing.
