Avocado plants imported Spain trees with patented hybrid
Criollo Michoacano & improved variety HATE
The underlying avocado Criollo Michoacano comes from the Michoacan region of Mexico. It is an improved variant of the TOPA-TOPA variety that has been and still is one of the best avocado seeds to be used as the subject of new avocado plants.
This improved variety Criollo Michoacano, ensures:
- Higher tolerances in water & soil salinity.
- Greater tolerance to pathogenic avocado diseases. Specifically, it shows increased resistance to pathogenic soil diseases, such as Phytophthora cinammomi, and fruit type fungi Rosellinia necatrix approaching the strengths of Duke 7 / Dusa / Toro Canyon clonal subjects)
- It ensures a significant improvement of the production having achieved productions of avocado fruits more homogeneous frame with larger diameter fruits of very delicious high commercial value.
To improve the variety Creole Michoacano have been used for more than three decades plant materials from different varieties of avocado trees in combination:
- The Nachar Hybrid (Israel).
The Nachar Hybrid makes avocado trees very hardy unsalted while ensuring enough high drought resistance
- Antillean plant material was also used (West India)
The Antillean Hybrid (West India) which gives high production potential to the crop 10-20% more than conventional avocado tree subjects. It also provides resistance to pathogenic soil diseases, such as Phytophthora cinammomi, and Rosellinia necatrix fruit fungi.
In addition to the crosses that have been applied to the Criollo Michoacano hybrid for a period of 30 years, to the new plants before inoculation a hardening technique is performed. and control of the resistance of the young plant.
Specifically, conditions of thermal stress and water stress are created, which consists of exposure of the plant without protection during both the Winter and the Summer period. For at least 6-7 days the young plant remains in water (flooded) while then remains without water for 7 consecutive days. This way you become much more durable and harden in extreme situations.
The subject of the Michoacano Creole hybrid presents improved and highly productive fruits in the top commercial HASS variety.
The Hass variety provides high quality fruits with a long shelf life both in the tree and in its harvesting and handling. The specific fruits / fruits of the subject Hass Criollo Michoacano gives:
- Possibility of maintenance and disposal after harvest for another 2 months.
- Allows long-term transport even by ship in case of export
- The graft used in young plants comes from adult trees on a farm of 100 hectares of very high yield over 80 kg per tree.
Therefore all young trees as they mature will produce homogeneously large Class A fruit calibers.
In terms of flowering begins in September – October while the fruits and berries of HASS Criollo Michoacano begin to grow from the end of December-January with a period of full growth of 6-7 months. Full fruit ripening for optimal levels of avocado oil fat is provided in late March with the possibility of remaining in the trees marginally until June.
This fact gives competitive advantage of a high producer price quality Hass avocado fruits due to high demand and limited off-season production compared to the standard commercial variety Hass.
For the proper development of avocado trees and the absorption of soil nutrients important is the PH of the soil to have values between 6-7 points. The subject imported from Spain Criollo Michoacano of variety hate has endurance of production dynamics with ph ground up to 7.80 degrees
It is therefore to imported from Spain subject Criollo Michoacano of variety hate a unique investment choice for growers – farmers who look to the future with planning and responsibility.

The secrets of growing a tree in a nutshell
Planting new seedlings – plants
The planting of new seedlings – avocado plants is important to be carried out mainly in early spring and alternatively in early September, provided that it is favored by the climate. At the same time during planting it is necessary to strengthen the planting soil with organic soil conditioners such as organic matter Compost , or well-to-do manure.
Cultivation frames. – Planting distances
The recommended planting distances for standard cultivation of the Hass variety Criollo Michoacano because the trees are dynamic and fast growing they are for medium to high planting density is 5 x 4. That is about 50 trees per acre. While for high density planting 3 × 4 meters and about 83 meters per acre.
It is important that they are pruned regularly after 2.5 years and beyond. The trees should not exceed 4 meters to facilitate their collection and as a compensation is proposed their lateral growth in the form of “open pine”.
Pollination of plants – trees
Flowers and pollination
A mature avocado tree can produce over a million flowers during the flowering period, most of which fall without producing fruit. The purpose behind the massive boom is to encourage pollen visits. In Crete and in Greece in general, a European bee successfully undertakes pollination.
The avocado has a “full” flower, but with an unusual behavior known as “primary dichotomy”. The avocado flower has functional male and female organs in one flower, but opens and closes twice in a period of two days – the first day as a functionally female and the next as a functionally male. Each opening stage lasts only about half a day.
Planting 2 varieties ( Type A and Type B ) on the farm for the better pollination
Irrigation water quality without salinity
Good quality water without salts
Avocado trees are generally demanding in terms of their need for water and the quality of irrigation water.
The critical stages of avocado, in terms of irrigation needs, are:
• The flowering & fruiting period.
• The period of fruit formation & development.
• The ripening period of the fruits in order to avoid fruit fall.
The water it contains is considered suitable for irrigating avocados chlorine salts less than 100 ppm (mg / l).
For new plantations, the average daily summer irrigation needs are defined by 4-8 liters per tree in the first year and from 80-150 liters per tree in the fourth year.
The thresholds and ceilings of the quantities necessary for the rational use of irrigation water in developed trees are set at 600 to 700 sq.m./acre/year. Short intervals of irrigation positively affect the size of the fruit and increase the concentration of oils in the fruit. See more information
Fertilizer – Fertilizers
What are the fertilizer requirements? avocado; The nutrition of avocado plants is determined by the composition of the soil. That is, we fertilize to cover any nutritional deficiencies in the soil, so as not to directly supply the tree with its nutritional needs. Avocados need nitrogen, primarily a little zinc
Recommended Organic Potassium Fertilizer. Ideal for intense flowering, juicy, rich fruits for a great harvest in avocado crops. POTENTIAL FERTILIZER.
During flowering and fruiting in Spring and Autumn, organic potassium fertilizer is recommended. See more information
Foliage Spraying and Fertilization.
The application of foliage fertilizers is sometimes promoted as an effective means of providing nutrients to the avocado. Various products are marketed as nutrients for avocados, some proponents even suggest that their products eliminate the need for nutrients applied to the soil. This article briefly reviews the literature on avocado foliage nutrition and examines the anatomy of avocado leaves and flowers in relation to nutrient intake.
During flowering, spray with a solution of zinc sulfates
If the avocado fruit has black spots and dryness on the skin of the fruit. This benefits the thrips insect
What are thrips?
The word thrips refers to a large group of insects of the order Thycanoptera.
What do you see
Because thrips have toxic substances in their saliva, you may see deformities in the shoots or flowers or fruits of the affected plants.
What can you do
Spray the plants with ecological insecticides, such as potassium soap (summer pulp) or pyrethrum plant extract. biological spray with natural natural pyrethrin solution
Avocado fungal infections
Avocado fungal disease is herbivorous / Due to poor drainage it affects the root system and gradually dries the tree.
Tree pruning. When do we prune the avocado?
The pruning of avocado is done after the end of the harvest and after the frosts of Winter to keep its height and shape for easy harvest
When pruning avocado trees, remember this: Always prune on purpose and avoid over-pruning or over-pruning avocado trees. Also keep in mind that what works for one tree may not work for another – pruning should be done on a case by case basis, as there are no two avocado trees.
Avocados have a long harvest time and are harvested gradually.
Avocado fruits remain hard when ripe on the tree and soften when cut.
Young avocado trees are sensitive to temperature and need to be protected
Especially in the summer months it is necessary to paint the trunk and its branches with ecological plastic paint
and spray the foliage with zeolite or kaolin
