CRESTON FS 799 seeds, Dnipropetrovsk region.

Stem height 1.60 - 1.65 meters, stem thick, straight, powerful, high in girth up to 18 cm, root powerful It lies in the ground at a depth of up to 420 cm, the leaves are medium, the caps are 27 cm - 29 cm in diameter, the seeds are small.

The essential differences of transgenic sunflower from ordinary hybrids and varieties are that it does not need to be treated with poisons from insects, fungicides from various diseases, and this indicates its environmental friendliness. plants.

It is characterized by good drought resistance up to + 60 C*, characterized by uniform ripening, resistant to lying down and shedding (heavy rains, hurricane wind, hail), sunflower is harvested in a straight line and does not require desiccation.

This hybrid is resistant to all sunflower diseases that affect common varieties and hybrids of sunflower and is not affected by diseases such as (powdery mildew, powdery mildew, downy mildew, rust, fomosis, white, gray, ash and dry rot, septoriosis, ascochitosis, bacteriosis, brown angular spotting, chlorosis, macrophomina, etc.). And it is practically not affected by these diseases.

This hybrid is resistant to all harmful insects due to the introduction into the DNA structure of the sunflower cell of the tetra gene isolated from the bitter wormwood plant, such as (sawdust, meadow moth, may beetle, sand honeydew, sunflower spike, firefly, weevil, gray southern weevil, white moth, winter cotton bollworm, aphid, etc.).

Resistant to abiotic stresses (sharp temperature changes from + 60 C* to - 12 C* during the entire vegetation period.

The sunflower is resistant to continuous-acting herbicides of the imidazoline group.

The content of sunflower oil in the oil hybrid is 52% - 54%.

This hybrid is self-pollinating and does not require the presence of bees.

This hybrid is resistant to acid rain and high temperatures, sunflower pollen does not burn at high temperatures.

It was sown in Ukraine and showed excellent yield results. Canadian sunflower CRESTON FS 799 perfectly tolerates early spring frosts - 14 C *.(//tractor-service.com)

The weight of 1000 seeds of Canadian transgenicoil hybrid CRESTON FS 799 sunflower is 66 grams.

Germination - 98%, Germination energy - 98%, Typicality - 100%, Moisture - 8%, Purity - 99.99%.

The yield of the transgenic hybridoil sunflower CRESTON FS 799 is 49 cents. - 50 cents. s 1 - hectare.

Sowing Sowing sunflower hybrids begins in early spring from March 1 to May 26 inclusively, it is possible to sow sunflowers at a temperature of + 1 C*, + 2 C *, as it is not afraid of spring frosts, sunflower sprouts appear in 8-10 days.

The rate of sowing of the Canadian transgenic hybrid CRESTON FS 799 per hectare is 3 kg, it is sown to a depth of 5 cm, in a dotted method with row spacings of 70 cm x 35 cm, which is made by pneumatic seeders SUPN - 8, SKPP - 12, LNG - 6 MF.

The sunflower yield depends on the density of planting. For southern steppe areas, the optimal planting density is 55,000 per hectare, for forest-steppe areas, 57,000 per hectare. For sunflowers, it is recommended to plow the field. Pre-sowing soil treatment should provide fine-grained, well-drained soil. Only well-dried soil is treated. Surface application of fertilizer at the same time protects the soil from soiling.

Use herbicides as needed. It is treated with a systemic herbicide of the imidazoline group Euro - Lighting, Euro-Land or Euro - Lang r.k. for the destruction of a wide range of annual cereals, perennial weeds, and dicotyledonous weeds, removes dead sunflowers that are not resistant to imidazolines, and also has a dual mechanism of action of the drug, kills both vegetative and seed-grown weeds, the active substance of the herbicide (imazethapyr 100 g/l, bioactivator NN-21) penetrates through the roots and leaves of plants xylem and phloem to the points of growth and blocks protein synthesis, which leads to the cessation of cell growth and the death of plants. The herbicide is applied with the help of ground sprayers, after the emergence of sunflower seedlings in the phase of 2 to 6 real sunflower leaves (sunflower seeds are not taken into account), the treatment is stopped when the sunflower is in the phase of 9-10 leaves. The consumption rate of herbicide is 1 liter - 1.2 liters per hectare.

Fertilizers Application of phosphorus andnitrogen fertilizers increases not only yield, but also oiliness. per 1 ha of superphosphate at the time of sowing and nitroammofoska 120 kg - 130 kg. per hectare before sowing or after sunflower sprouts.

Insecticides are not used, as this hybrid is resistant to all harmful insects, preservatives are not used at all.

The vegetation period of the transgenic Canadian sunflower hybrid CRESTON FS - 799 from sowing to harvesting is 105-110 days (mid-ripe).

Sunflower harvesting should begin when 90% of the sunflower baskets turn brown, and harvesting is done with the usual Don, Jondyr, Case combines.
