How to Prevent Gummosis in Citrus Fruits After DANA

Valencian Citrusadinoyangena oferty to combat gummosis

The floods caused by Storm DANA since October 29th could lead to significant damage in the upcoming citrus crop due to the risk of gummosis. Elected Officials react quickly and decisively to minimize the potential impact.

The Valencian Community’s Agriculture Consellería has begun distributing 80% fosetyl fungicide to combat this disease, which poses a particularly serious threat to citrus crops. This measure, representing an investment of 440,000 euros, will benefit nearly one hundred municipalities affected by the flooding.

Farmers seeking access to the fungicide can apply through city councils, cooperatives or agrarian transformation societies, requesting the volume needed for their affected citrus groves. Each request must cover a minimum of 5 hectares. The distribution will continue while supplies last.

More than 15,000 hectares of citrus groves are at risk due to the recent events. The cause of this threat, the fungus Phytophthora citrophthora, thrives in warm temperatures between 18 and 25 degrees Celsius. This destructive fungus spreads readily under these optimal conditions resulting miso.

Gummosis is characterized by the secretion of amber-colored, rubbery substances from the trunk and branches of affected plants. The

resulting gum build-up hinders the normal flow of sap, leading to leaves becoming pale green with yellowing veins.

Citrus trees that survived the floods but experienced root asphyxiation will likely develop gummosis and collar and root rot.

Recognizing the symptoms of gummosis is critical for timely intervention. Look for the following:

  • Gum exudates oozing from both branches and the trunk
  • Pale green leaves with yellowing veins
  • Collar rot

Citrus fruit becomes small and falls prematurely, while branches experience dehydration and die. In extreme cases, the entire tree succumbs.

Citrus crops are particularly susceptible to Phytophthora infections, which pose more serious risks compared to other crops. Clementine varieties are particularly vulnerable, making targeted preventative measures important.

To mitigate the impending threat, the Valencian Institute of Agrarian Research (IVIA) and the Plant Health Service have collaborated to develop a preventative and reactive strategy containing specific recommendations aimed

at minimizing the impact of gummosis

Preventing Gummosis:

Key Recommendations

  • Remove accumulated soil from tree trunks.

  • **

Remove plastic protectors. These trap moisture around

The action plan highlights early intervention

  • **Apply

systemic fungicides** such as fosetyl-Al, potassium phosphonates, and metalaxyl. It underscores the importance of early intervention, urging prompt action to minimize damage. To successfully combat this disease, swift and coordinated action is crucial for protecting this valuable cropland.

## Valencian Officials Take Action ​Against Gummosis Threat

**(Intro music)**

**Interviewer:** Welcome back to the program. We’re continuing our coverage of the aftermath ⁣of ⁣Storm DANA, which has devastated citrus groves across ⁤the Valencian Community.‌

Joining us today is [Guest Name],⁤ Agricultural expert ​and [Guest Affiliation].

[Guest Name], thanks for being here. Can you ⁤explain​ the threat ‌gummosis poses to the citrus industry, particularly in​ the wake of these ⁣floods?

**Guest:** ⁢Certainly.

Gummosis is a serious fungal disease caused by *Phytophthora citrophthora*. This fungus thrives in ‌warm, wet conditions, exactly the kind we saw following ⁢Storm DANA.

Essentially, ⁤the‍ fungus attacks the trees, causing them to​ ooze ‌a sticky amber ‌resin. This gum buildup blocks‌ the flow of nutrients and water, weakening the tree and eventually killing it.

The floods have created ideal conditions for this fungus to spread, putting over ‌15,000 hectares of citrus groves at risk. This is a major concern ⁣for the⁤ Valencian‍ economy, as citrus ⁤is a vital ⁤crop⁢ for the region.

**Interviewer:** ‌What measures are being taken to combat this ‌threat?

**Guest:**

The Valencian ​government ‍is taking swift ‌action. They’ve begun distributing an ‌80% fosetyl fungicide ⁢to​ affected ⁢farmers. This is a significant financial ‌commitment, costing 440,000 euros, but crucial to protect

the citrus industry.

Farmers can apply for the fungicide through their local councils, cooperatives or ​agricultural societies. ​

**Interviewer:**

That’s reassuring to ​hear. What message do you have for citrus​ growers ‌in the region?

**Guest**:

I urge​ all⁢ citrus growers affected by the floods to apply for the fungicide ​as⁢ soon‌ as ⁣possible. Early intervention is key to stopping the spread of gummosis. By ‌working together, we can mitigate the damage and protect this vital industry.
