Tavan Chile continues to revolutionize the management of diseases caused by fungi and bacteria that affect the growth and productivity of various crops, including cherries.
To its wide range of treatments, among which stand out WERT and BACTOFUS, now added AXIONFULL.
Continuing with its commitment to providing effective, sustainable and environmentally friendly alternatives, AXION FULL is a biotechnological, organic and zero-waste product. Specially designed to inhibit the proliferation of fungi and bacteria in the roots, soil and vascular bundles.
Among its advantages, AXION FULL It acts in a systemic, ascending and localized way, increasing the defenses and hardening the cell membranes of the plants, thus increasing resistance to infections.Since it is a specific product for soil, roots and vascular bundles, it can be applied via irrigation or locally.
Another advantage is that sIt can be applied at any time of the year, although the Tavan Chile team It is recommended to apply it during periods of root flush. -complementing it with the soil oxygenator OXIROOTS and the rooting TAVAN ROOTS-; beginning of sprouting and post-harvest, or in specific situations that require urgent application.
It should also be noted that, being a biotechnological product specially designed and developed for these purposes, it is friendly to most microorganisms beneficial to plants, i.e., It will not affect the normal development of soil microflora, allowing for better expression of crops in general.On the other hand, it has the advantage of being designed to be freely incorporated and translocated through the tissues and vascular system, even during periods of vegetative recess.
Sanitation throughout the plant
Biochemistry Tavan Chile landed in the country almost 20 years ago with a revolutionary proposal for the comprehensive management of diseases caused by fungi and bacteria that attack various crops, including cherries, but also plums, walnuts, European hazelnuts, avocados, among others.
In the case of cherry trees, José Ignacio Tagle, central zone manager for Tavan Chile, explains which fungi and bacteria can affect the soil, the roots, the vascular bundles and the consequences of not tackling these threats in time.
“In Chile we find, mainly, mushrooms Phytophtora sp, Armilaria sp, and bacteria like Agrobacterium tumefaciens, the causal agent of “neck gall” (a “tumor” that forms at the base of the neck of plants). These fungi and bacteria are classified as phytopathogenic microorganisms, since they cause significant losses in the production of fruit trees and other species,” explains Tagle.
–What damage do they cause to the plant?
“In general, mushrooms Phytophtora sp, Armilaria sp They produce rot at the level of roots, neck and vascular necrosis of the plant, which leads to a General weakening, delayed sprouting, decreased vegetative growth, loss of vigor and production, and even the death of plants.
In the case of “neck gall”, this bacteria does not cause rot or necrosis in the root or neck, but rather “tumours” in the root and at the base of the neck, which “strangulate” and “parasitize” the roots. This causes a progressive death of the root and vascular system in the lower part of the tree. In certain cases, tumours also appear on trunks and branches. Very advanced infections cause weakening, low production and death of the plants.
-If these phytopathogens are not managed properly, what happens to the plants?
“Poor management of these fungi and bacteria can lead to a significant decrease in production, death of plants and even total loss of an orchard.. Especially when we talk about fungi, since those that affect the root are very aggressive, It can cause a decrease in vigor and death of plants in a short time.There have been cases where even “sudden death” of plants has occurred.
As for the Agrobacterium sp, it is also extremely important to carry out preventive treatments, since although this disease will affect the vigor of the plants in the long term, it will give us more time to carry out adequate controls."
-When is it appropriate to carry out these procedures to keep plants free from these threats?
“It is important to constantly monitor the garden, since These symptoms can appear at any stage of plant development, especially when we have had very rainy winters., where the plants have been subjected to waterlogging for a long time.
The same happens with excessive irrigation in very heavy soils or with low water infiltration.. These can cause root asphyxia and then fungal attacks, leading to a loss of root mass and possible rotting of the neck. In these cases, we could make applications throughout the vegetative cycle, and even, for certain cases, during winter dormancy periods. As a general preventive recommendation for fungi and bacteria in soil, roots and vascular bundles, It is recommended to apply AXIONFULL from the beginning of the root flush.. With this we seek to disinfect the roots and bulbs of the soil, thinking that the new roots grow healthy and in a substrate with minimal or no pressure from these microorganisms.”
