Bolivia: control de la mosca de la fruta en chirimoya

La mosca de la fruta es una plaga de mayor importancia en América latina, y solo en Bolivia, esta plaga causa pérdida de 113 millones de dólares cada año a los productores de frutas y hortalizas.

Los productores y productoras de chirimoya pueden revisar la Lista Verde producida por Plantwise que brinda asesoramiento sobre la prevención y el manejo cultural y biológico de la mosca de la fruta para evitar pérdidas importantes de sus cosechas.

Algunas medidas para el control de la mosca incluyen el manejo de malezas, recolección de frutos caídos, adelantar la cosecha, colocar trampas de feromonas y el uso de enemigos naturales ya como Beauveria bassiana.

Factsheet of the month: November 2015 – Using natural nematicide plants against banana nematodes

20157800105Researchers at Queen’s University, Belfast, have developed a new method to control the parasitic nematodes that devastate banana crops and cause billions of dollars of crop losses annually. It is hoped that this new technology will reduce these losses, boosting the incomes of subsistence farmers in developing countries.

Nematodes are notoriously difficult to control, and the most effective management practices are preventative. Chemical control using nematicides is not recommended for the control of nematodes as these chemicals are often expensive and highly toxic to both humans and the environment.  Read more of this post

Factsheet of the month: October 2015 – Grain storage in metal silos against insect pests

20157800264Last week, 193 Member States of the United Nations adopted the new Sustainable Development Agenda to end poverty by 2030. This came at the beginning of a three-day Summit on Sustainable Development during which focussed on implanting changes that will see the Agenda achieve its ambitious aims. The Agenda, consisting of 17 Sustainable Development Goals (SDG), will help countries to develop their policies over the next 15 years.

The second SDG on the list is to “End hunger, achieve food security and improved nutrition, and promote sustainable agriculture.” Globally, 1 in 9 people are undernourished, the majority of whom are in developing countries where food loss is an important factor. Food loss is the food that gets spilled or spoilt before it reaches its final product or retail stage, whereas food waste happens at the retailer or consumer stage. Read more of this post

Bolivia: caso confirmado de la Moniliasis del cacao

Frutos con varios síntomas (CABI)

Frutos con varios síntomas (CABI)

En junio 2015, se confirmó la presencia del hongo de la Moniliasis del cacao en Alto Beni, Departamento de La Paz a donde 85% de la producción de cacao es producida por aproximadamente 3000 pequeños y pequeñas agricultores. Este hongo (Moniliophthora roreri) es limitado en 13 países de América Latina y causa pérdidas importantes por los productores y productoras. Los síntomas característicos del hongo en los frutos incluyen madurez prematura, deformación, lesiones largas de color marrón y necrosis interna de los tejidos.

Para mantener un cultivo sano y prevenir la dispersión del hongo, revise la Lista Verde sobre la Moniliasis del cacao o para más detalles técnicos revise la Hoja técnica de Plantwise. Si se detecta los síntomas en regiones libres de la enfermedad, contacte el Ministerio de Agricultura de su país para recomendaciones de control locales.

Healing Plants to Feed a Nation

Growing up in a small village in Western Kenya, I often accompanied my mother and other village women on customary weeding expeditions. Whenever we came across sick plants in the fields—which was all too often—my mother would instruct me to pull them out and cast them aside.

I did as she asked, but wondered to myself: Why do we simply throw out the plants instead of doing something to make them better?

At times, my mother lost nearly 80 percent of her tomatoes to plant disease. The loss was so bad that she eventually stopped growing tomatoes all together. Yet when one of our cows got sick, my mother would call a veterinarian to come and treat the cow. I wondered: Were there no doctors who could also cure our plants?

I turned this curiosity into a career in science and became the first child in my family to attend university as well as the first woman in my village to earn a science degree. Seeking answers to my childhood questions, I studied botany and zoology as an undergraduate to better understand the diversity of crop and animal pests and diseases afflicting farmers like my mother in Kenya and her peers across Africa. I wanted nothing more than to find a practical solution.

So, I became a plant doctor

Wheat production in Pakistan – Producción de trigo en México

Infected wheat by P. striiformis/Trigo infectado por P. striiformis (Z. Kang)

Infected wheat by P. striiformis/Trigo infectado por P. striiformis (Z. Kang)


According to Reuters (source provided by ProMED-mail), farmers from districts southeast of Islamabad in Punjab province have seen their crops affected by unusual weather this year. First affected by hailstorm and now by heavy rain and cold weather, wheat fields of the region have been damaged severely. Some farmers have lost up to 70 % of their fields and are still waiting to harvest their crops three weeks behind schedule. Experts said that delays in harvesting and damaged plants can increase the chances of attack by yellow rust also called stripe rust (Puccinia striiformis). The fungal disease causes yellow leaf stripes, loss of vigour and stunting of plants.

Extension officers can review factsheets provided by Plantwise such as the Green and Yellow list written in Zambia* and the Plantwise technical factsheet on yellow rust to create a new and country-specific extension message for Pakistan on how to prevent and manage the disease.

*Please note that the pesticides mentioned in this factsheets are specific to Zambia and before giving recommendations check against your national registered pesticide lists.


Según El Diario (fuente proporcionada por ProMED-mail), la producción de trigo en la región de Nuevo Casas Grandes (Chihuahua) se ve afectada por la roya amarilla (causada por el hongo Puccinia striiformis) cual ocasionará una disminución del rendimiento. La roya amarilla es una enfermedad muy agresiva en condiciones favorables para su desarrollo (agua libre, temperatura de 10-15 °C y viento) y cuando se usó variedades susceptibles. Es la enfermedad que produce mayores pérdidas en el cultivo del trigo debido a su gran capacidad de dispersión a largas distancias. Se identifica por la formación des estrías estrechas en las hojas, pérdida de vigor y retraso en el crecimiento de las plantas.

Los extensionistas pueden revisar las hojas informativas de Plantwise como la Lista Verde y Amarilla elaborada en Zambia* y la hoja técnica de Plantwise sobre la roya amarilla para crear material nuevo y específico para México sobre cómo prevenir y manejar la enfermedad.

*Por favor, tenga en cuenta que las pesticidas indicadas en la hoja informativa son específicas para Zambia y antes de dar recomendaciones verificar la lista de pesticidas registradas en su país.
