The invention is illustrated by, but not limited to, the following examples. EXPERIMENTS Preparation of the water-soluble unit comprising captan (unit A) The water-soluble units comprise a chamber containing captan (captan 80 WDG, Merpan). They were prepared using a vertical FFS machine that forms the PVA sachet (Aicello PT 40) and fills it with a measured amount of captan (Merpan). The water-soluble unit comprising captan was vacuum-sealed using hot stick welding or impulse welding. EXAMPLE01, Water-soluble unit packaged in a vacuum-sealed bag. Unit A was placed in a sealed bag, (3-layer laminated PE / AL / PET film (PlastoSac)). The sealed bag was vacuum sealed for 30 seconds using impulse welding. The vacuum inside the sealed bag is less than 600 mmHg. EXAMPLE 2- Water-soluble unit packaged in a sealed bag, the sealed bag is sealed by ambient pressure. Unit A was placed in a cross-linked PE Ziploc bag. The bag was sealed using a Ziploc. The pressure is ambient pressure. There is no vacuum in the sealed bag. Stability tests: Examples 1 and 2 were stored at 40°C for 8 weeks and parameters such as (1) dissolution rate (start and complete dissolution), (2) sieve residues (filter nozzle and upper sieve filter) and bulging were checked. Test 1, Dissolution time test under laboratory conditions, based on CIPAC MT 176 A 10 cm² strip of PVA film (taken from Examples 1 and 2, as well as from a new, unstored PVA film) was hung on a metal hook attached to a plastic cover. 2. The strips were then immersed in a beaker containing 100 ml of standard hard water (500 ppm hardness, pH 7.0–8.0, Ca++:Mg++ = 4:1) in which captan 80 WDG was dispersed. The water temperature was maintained at 20°C or below. 3. The film strips were kept in the captan dispersion for 10 minutes without stirring, followed by 10 minutes with stirring using a magnetic stir bar at 1500 RPM. 4. The dispersion was poured through a 150 µm sieve, and the residue was observed. 5. The time to initial dissolution of the film strip was measured. cbhQnn / zznz / B / YiAi EXAMPLE 1 - vacuum sealed EXAMPLE 2 - sealed at ambient pressure New PVA film Dissolution time Time to start of dissolution of the chamber film 30 seconds 4 minutes 30 seconds Residue at the end of the test Some < 1mm pieces of film Several 2-3mm pieces of film No residue The results showed that the unit stored under vacuum (EXAMPLE 1) was more stable than the unit not stored under vacuum (EXAMPLE 2). The time required to initiate dissolution of the chamber wall film in Example 1 was the same as for the new PVA strip tested under the same conditions. Furthermore, the amount of residue on the sieve in Example 1 was less than in Example 2, demonstrating that the overall dissolution time for Example 1 is shorter than for Example 2. Test 2, Field simulation test: Materials: The 1000-liter commercial spray tank (50% volume) contains water at a cold temperature of 5°C and commercial fertilizer, Calcium Chloride (180 g) and Magnesium Chloride Hexahydrate (80 g), with a water hardness of at least 342 ppm and a molar ratio of Ca to Mg of 4:1. (pH of 7.9) The essay: Step 1. The units from Example 1 and 2 were placed in the upper sieve of the spray tank. Step 2. Cold running water (5°C) was applied at a pressure of 4 Bar to the water-soluble units placed on the upper sieve. Throughout step 2, the time in seconds and the volume of water in liters were measured for each unit of solution. In addition, the internal mixing nozzles and filters were in operating mode and jet agitation was maintained for 10 minutes. Step 3. The spray solution obtained from step 2 was applied using an arm sprayer with a T-jet ceramic spray nozzle with a nozzle filter with 50 and 80 mesh. Once step 3 was completed, the sieve residue in the nozzles, nozzle filters and pump filter as well as the top sieve filter were checked by a visual inspection. The results are shown in Table 2. EXAMPLE 1 - Vacuum Sealing EXAMPLE 2 - Ambient Pressure Sealing Dissolution Time Time to start dissolving of the camera film 7 seconds 15 seconds Total dissolution 2 minutes 5 minutes Sieve on top of sprayer Clean Residue Main filter observation Clean Clean Nozzle filter observation Clean Clean The results showed that the unit that was stored in a vacuum (EXAMPLE 1) was more stable than the unit that was not kept in a vacuum (EXAMPLE 2). Test 3. Volume of the water-soluble unit comprising the swell after storage for 8 weeks at 40°C. The chamber bulge is an additional test that reflects the stability of the water-soluble unit. The bulging of the camera was recorded as a visual observation. The results are shown in Figures 1A-1B and 2A-2B. The results showed that the volume of the water-soluble unit that was not kept under vacuum (example 2) (figure 1A-1B) increased by at least 30%. Conclusion: The packaging of the invention for a water-soluble unit comprising at least one agricultural material, wherein the water-soluble unit comprising at least one agricultural material is kept in a vacuum-sealed bag, demonstrated less change in chamber film dissolution time, sieve residue, and chamber bulge compared to the water-soluble unit comprising at least one agricultural material, which was kept in a sealed bag at ambient pressure (not vacuum). Furthermore, the priority documents of this application are incorporated herein by reference in their entirety.
