La biofumigación es moderna pero aún algo desconocida para la mayoría de agricultores de hortícolas y otros eslabones de la cadena de suministro. Se trata de algo paradójico, ya que la biofumigación aporta un gran número de beneficios al suelo y a la salud de la planta, que finalmente puede resultar en una menor aplicación de pesticidas.
La biofumigación actúa en dos tipos de patógenos a través de los siguientes mecanismos. Por un lado la acción de un “cultivo trampa” sirve para luchar contra los nematodos. De esta forma al cultivar determinadas variedades de rábano, estos organismos no obtienen los nutrientes que necesitan para crear una nueva generación; por lo que mueren y se interrumpe su ciclo de población. El segundo mecanismo utiliza los componentes naturales de determinadas especies de brassica, los cuales generan gases llamados isotiocianatos; tóxicos para muchos hongos y bacterias de suelo pero que no perjudican a aquellos organismos beneficiosos.
Como se ha mencionado previamente, la biofumigación es una técnica novedosa y su cultivo requiere un especial manejo y gestión. Nos complace ofrecerle nuestro asesoramiento para usar este producto de la forma adecuada.
Grafting vegetable plants is becoming standard in more and more countries. The advantages like yield boost and quality improvement are obvious and make grafting easy to calculate. Rootstocks normally have much better resistance to soil-borne pathogens and share this robustness with the main variety by grafting. Compatibility with the main variety is crucial.
At agro-TIP we furthermore pay attention to better nutrient uptake of the rootstock and – even more important – to upgrade quality of the harvested goods. Achieving higher content of ingredients or enhanced internal quality is possible as well. Even earliness can be improved when choosing the right rootstock.
In the breeding and development process agro-TIP is focusing mainly on heat tolerant Broccoli Hybrids
both for “hot and dry” and “hot and humid” growing condition. Always considering main market supply
we are totally aware of the needs and special demands of niche markets.
Some characteristics are not negotiable and valid across the globe under any growing conditions and -period. They are of main interest for the daily work in the field and in the subsequent supply chain. Nevertheless, market requirements sometimes vary in details and reflect the challenges in plant breeding.
Among all vegetable species Broccoli is known as one of the healthiest with very high content of anti-carcinogenic ingredients such as Sulphoraphan. These ingredients are worth to be considered in the breeding process and to make it available to everybody in this way.
It is understood that watermelon originates from the tropical of Africa. As a consequence it’s no wonder that watermelon requires heat as no other vegetable crop. Wild varieties were used as natural water supply by camel trains thru deserts. Even then people appreciated its refreshing effect and well tasting flesh. By means of breeding over many years taste, sugar content, size etc were improved. But the discovery of seedless watermelon varieties in the 1950s has been by far the biggest innovation in the history of watermelon breeding. Still watermelon is among the top 5 vegetables being produced world-wide in terms of quantity.
agro-TIP runs a very active and creative watermelon breeding program offering both diploid (seeded) and triploid (seedless) watermelon hybrids. To widen and improve the portfolio is not just a slogan but our daily motivation. Selecting the safest place for seed production in terms of disease free areas is crucial in watermelon and of highest priority for agro-TIP.
The international character of tomatoes is unbeaten! Alike customer preferences and versatile manifestation in sizes, shapes and color tomatoes are grown almost everywhere around the globe.

Sweet corn is separated into different gene classes that refer to the sugar content of the kernels. Old standard types or ‘single sweet’s’ (SU) have lowest sugar content. ‘sugar enhanced’ (SE) types have better sweetness but the real revolution came up in the second half of the 1900’s. ‘Super sweet’ (sH2) entered the markets starting in the US in the 1980’s. The super sweets – also called shrunken 2 type – produce notably higher sugar contents by 4 to 10 time higher than SU corn. Furthermore the sugar-to-starch conversion is by far slower and enables growers to extend the harvest window. Retailer benefit from that trait because they can ship and store longer.
agro-TIP is convinced of super sweet / sH2 types and mainly offers varieties of this gene class. Still super sweets are not accepted everywhere but history shows that the convincing properties of high sugar production and extremely long shelf life will dominate on long term.
Squash shows up in different type all-around the globe. Light to medium-light green type with cylindrical or bulbous shape, dark green zucchini types, caserta or round types – squash appears in all nuances of green and any shape from round to long cylindrical.

Spinach is all about resistance to DM (Peronospora farinosa f. sp. spinaciae). Every few years new races show up and lead to intensive tests of the entire lines. Second important aspect is bolting tolerance that is deciding about the proper sowing slot and growing area.
agro–TIP’s spinach hybrids are very well adapted to many growing areas. They provide high yield and pack-out and furthermore an ease of harvest by an upright plant habit.
Onion is one of most grown vegetable generally appearing in many dishes mostly as a spicing vegetable. Its health effects are exceptionally high which is attributed to sulfur-containing sulfides and selenium compounds that have anti-carcinogenic, antioxidant, antimicrobial and further beneficial effects on human health.
