WHO CAUSES IT?

Thrips are small insects belonging to the order Thysanoptera, and some species can be important pests in cannabis crops. These insects feed on plant tissues, causing direct damage by piercing plant cells and sucking sap, which can weaken the plant and make it more susceptible to other diseases.

SYMPTOMS

Symptoms of thrips attack on cannabis may include the presence of small silver or tan Taches on the leaves, caused by the insects feeding. In addition, deformations of the leaves, curling of the edges, and in severe cases, defoliation and reduction in plant growth can be observed.

Recommendations
