ALERT: Neonic pesticides in tap water react with chlorine to create hazardous chemicals that are 300 times more toxic
Researchers warn that conventional methods for treating water can trigger chemical reactions in neonicotinoid contaminants. The resulting metabolites are proven to be far more toxic than the original “neonic” pesticides. Their newest experiment followed up on their discovery of neonicotinoids in tap water sources. The team investigated the risk of the pesticides getting exposed to chlorine-based water treatments and transforming into chlorinated disinfection […]

Long-term outlooks: Australian farmers eliminate herbicide-resistant “superweeds” using natural non-herbicidal methods
Decades ago, Australian farmers stopped using glyphosate and other herbicides to get rid of superweeds and seeds in their plots. Instead, they used natural methods of weed control and management that worked much better than toxic chemicals. Farms in Western Australia raise wheat and barley as the main food crops. The biggest threat comes from ryegrass superweeds that developed resistance […]

Study: Habitat destruction to blame for the demise of monarch butterflies in California
Bees are not the only pollinating insects in danger of disappearing from the face of the Earth. The population of monarch butterflies in California has dwindled to alarming levels after the destruction of so much of their natural habitat. A recent study by the Xerces Society for Invertebrate Conservation warns that the number of butterflies spending the […]

Researchers build a robotic platform to observe the effects of neonicotinoids on bee behavior
A video camera-controlling robot was used to record the negative effects of neonicotinoids on bumblebees. The Harvard-designed machine was able to record and show the disruptive effects of the pesticides on the way the bees behaved, interacted with other members of their nest, and regulated their body temperature. Bees are in serious danger from widely used neonicotinoid pesticides. […]

Potential natural herbicide found in Mexican marigold essential oil
The Mexican marigold (Tagetes erecta) was evaluated by a Thai study that sought out a natural and effective replacement for synthetic herbicides. The essential oils found in the plant demonstrated sufficient effectiveness against cockspur grass (Echinochloa cruss-galli) before and after the emergence of the weed. King Mongkut’s Institute of Technology supported this research effort. The findings came out in […]

Peppermint essential oil exhibits powerful antifungal activity
Peppermint isn’t just a spice that imbues meals with a cool, peppery flavor. Indian researchers believe the essential oil of the plant can serve as a natural fungicide for Fusarium head blight. The blight is caused by the pathogenic fungi Fusarium sporotrichioides. This common plant disease targets important cereal crops, including barley, maize, oats, rice, and […]

Many botanical extracts show promise as natural, alternative insecticides
Horn flies and stable flies are growing more resistant to commonly-used chemical pesticides. A government-supported study evaluated plant-based insecticides and insect repellents as alternative means of controlling the populations of these biting flies. Biting flies feed on the blood of cattle and other livestock. Not only do their painful bites and swarming numbers disrupt the […]

Peppermint essential oil can prevent blight in wheat
Indian researchers investigated the possibility of using peppermint (Mentha piperita) as a fungicide for agricultural use. They tested its essential oil on Fusarium sporotrichioides, the pathogenic fungi responsible for Fusarium head blight that ruins wheat crops. The research effort received support from the Defence Food Research Laboratory. Its results were published in the science journal Pharmacognosy […]

Scientists investigate the use of various botanical extracts as natural insecticides
A new research paper looks into natural means of pest control for horn flies (Haematobia irritans) and stable flies (Stomoxys calcitrans) that harm domestic cattle. The paper identifies a number of plants that could potentially manage these biting flies without using dangerous chemical insecticides. The study was supported by the Agricultural Research Service. It was published in […]

Researchers look at two parasitoids from Pakistan as potential natural pest control
The fruit orchards of California are under attack by Asian citrus psyllids (Diaphorina citri). These insect pests spread the huanglongbing disease that kills profitable citrus plants. To combat them, researchers are using two parasitoid wasps from Pakistan, the original home of the psyllid menace. The psyllids are an invasive species from southern Asia that first […]
