Use of resistant cultivars, removal of weeds around the greenhouse, use of phosphorus-containing fertilizers, use of Capras fungicide, use of Deco Fuski product.

Apple worm: plowing - pruning - removing weeds - collecting infected fruits - using chemical poisons such as Zolon (1.5 per thousand), Gesranthione (2 per thousand), Diazinon (1.5 per thousand) that the time of fighting is done by using more awareness notices.Root white worm: deep plowing - removing weeds - chemical method: 4 to 5 grams of diazinon powder per square meter of soil, which is done after spraying, which is usually done in early spring and early summer. takeRosacea long branch beetle: by cutting and burning the infected branches, the population of the pest can be reduced. To control this pest, the first spraying is done on the first of July, and to obtain a successful result, the second spraying is repeated 10-15 days later. Strong penetration poisons should be used. Apple surface powdery mildew: pruning of branches and branches - resistant cultivars such as Lebanese yellow apple, (Lishner, Golden) - use of sulfur fungicides, Karatan, the first time when the buds swell, the second time after falling Petals and the third turn depends on weather conditions

N-Nitrogen: This element is known as the most important food element in plants. Because nitrogen is an important part of the chlorophyll molecule and without nitrogen the paraffin rings on the four sides of the chlorophyll molecule will not be formed, so the first symptoms of nitrogen deficiency are paleness and chlorosis of old leaves. P - Phosphorus: In general, phosphorus deficiency reduces the processing speed and productivity of carbohydrates, while the production of carbohydrates continues through photosynthesis. As a result of this process, the gradual increase of carbohydrates and the dark green color of the leaves are created. In some plants, phosphorus deficiency causes purple color, such as tomatoes. Because phosphorus is liquid in the plant, when the plant is deficient in phosphorus, the older leaves are transferred to the active meristem leaves and the effect of this deficiency is visible in the lower parts of the (older) plant. K-Potassium: Potassium plays a key role in photosynthesis. Potassium ion accelerates the transport of materials resulting from photosynthesis This is probably related to photophosphorylation processes. So that when the amount of K+ increases in the plant, the production of ATP is likely to increase, which is necessary in loading phloem vessels with photosynthetic materials. An increase in photophosphorylation and photosynthetic electron transfer was observed in plants that are well supplied with potassium ions. The rate of photosynthesis is reduced in many species that are exposed to salt stress (NaCl).

The best type of sulfur for agriculture is bentonite-free refinery sulfur with 99% purity. Pastille or lentil, granule or powder forms with 99% purity are very suitable for use in agriculture. These types of sulfur are completely yellow and do not dissolve directly in water. As much as possible, mineral sulfur and bentonite should not be used.
