"Monterey" STRAWBERRY cultivar performs well under walk-in tunnel in Colombia. La variedad de FRUTILLA (FRESA) "Monterey" se adapta bien al cultivo en macrotunel en Colombia

In Colombia, high-tunnel systems may be a viable alternative for increasing the yields of strawberry crops due to their ability to prevent fruit losses and plant damage caused during periods of high precipitation. This study aimed to compare the yield and its relationship with vegetative and reproductive components of Albion and Monterey strawberry cultivars, established in open-field and high-tunnel systems in Cajica (Colombia), at 2,562 m a.s.l. and 4°56´N, 74°00´W. ‘Monterey’, a cultivar with more vigor, presented a higher yield that ‘Albion’. The growth conditions in the high-tunnel system promotedrapid vegetative growth in the ‘Monterey’ plants, with an increase in yield and a decrease in losses. The ‘Albion’ cultivar plants in the high-tunnel system presented a decrease in fruit losses; however, these plants did not present differences in yield compared to plants in the open-filed system. Despite the benefits of a decrease in fruit losses due to rot seen in the high-tunnel system, this system had an increase in powdery mildew and calcium deficiency.

Guía para reconocimiento de plagas, organismos benéficos y enfermedades del cultivo de FRUTILLA (FRESA) - Guidelines of pests, beneficial organisms and diseases of the STRAWBERRY crop


El cultivo de frutilla es una de las principales actividades de pequeños productores de Jujuy. El mismo se caracteriza por alto costo de inversión, por ser altamente demandante de mano de obra, y por estar sujeto al ataque de plagas y enfermedades durante todo el ciclo productivo. En este contexto, el objetivo de esta guía es brindar a los pequeños productores una herramienta que les facilite la identificación, la prevención y el control de las plagas y enfermedades más frecuentes.
Con esta información se busca orientar al productor para que tome una decisión más acertada en cuanto a su accionar y para que vaya tomando conciencia de que es posible una producción sustentable, cuidando el ambiente, su salud, la de su familia y la de los consumidores.
Otro fin de esta guía es la materializar los temas abordados durante las capacitaciones y recorridas de campo en el marco del proyecto Fortalecimiento ydesarrollo del sector frutillero en la provincia deJujuy mediante adopción de tecnologíaapropiada”, financiado por PRODERI y en el cual participan más de 70 pequeños productores de la provincia de Jujuy.
Como punto de partida, iniciamos esta guía remarcando que una condición fundamental en el cultivo de frutilla es utilizar plantas sanas y de tamaño adecuado.

FRESA. Incentivo para estudiar las plagas y enfermedades en suelos sin fumigar en California

More than $1 million in state and federal research grants are approved for the California Strawberry Commission to improve soil health. The CSC says the future sustainability for California strawberry farmers involves continued research to find non-chemical alternatives to fumigants. 
 


More than $1 million in state and federal research grants will go to the California Strawberry Commission (CSC) to improve soil health.

The research dollars will advance science on sustaining healthy soils to control plant diseases, and reduce the need for soil fumigation. The research will focus on experimental soil-borne disease management systems using biologically active soil treatments.

According to the CSC, California strawberry farmers are leaders in research to reduce pesticide use. Over the last six years, the commission has invested heavily in fumigant alternatives research, including soilless systems, steam, mustard seed meal, and anaerobic soil disinfestation.

“These recent grant awards will allow us to continue working with the top researchers in the world to find sustainable solutions to managing plant disease and pests in the soil without fumigation,” according to  Dan Legard, the CSC’s vice-president of research and grower education.
“We look forward to more robust research aimed at new ways to create healthy soil environments for strawberries.”

The CSC says future sustainability for California strawberry farmers involves continued research to find non-chemical alternatives to fumigants.
The CSC says strawberry farmers have been recognized globally for phasing out methyl bromide to help protect the Earth's ozone layer. The loss of methyl bromide has left farmers with only one remaining tool to clean the soil - chloropicrin.
Chloropicrin does not control all soil-borne diseases, the commission says. Instances of the macrophomina and fusarium diseases have increased in recent years.

The grants will help strawberry farmers find other soil cleaning alternatives.
The million-dollar in research grants come from two primary sources:
-  $298,472 from the California Department of Pesticide Regulation to evaluate soil-borne disease management systems which use biologically active soil treatments in combination with reduced rates of fumigants.

The research aims to significantly reduce the amount of fumigants needed to treat soil diseases before planting, and improve the efficacy of biological approaches.

Rick Tomlinson, president of the California Strawberry Commission, says, “We are honored to be recognized for our pioneering research to reduce fumigant use with these significant grants to move our research to the next level,”

California produces more than 85 percent of all U.S.-grown strawberries.
The CSC is a state government agency which represents all California strawberry shippers, processors and farmers. With an emphasis on food safety education, commission activities focus on production and nutrition research, trade relations, public policy, marketing, and communications.
