LEARN TO DIFFERENTIATE THE DIFFERENT PESTS THAT AFFECT MARIJUANA CROPS
Mites, whiteflies, thrips, aphids, mildew, mold flies and Botrytis are the most common pests and diseases that can affect our marijuana plants. At Ganesh Grow we teach you how to differentiate what the plants have and from there how to treat it to eradicate the pest or disease.
Adult thrips have a varied diet based mainly on pollen, but the larva feeds on plant tissues, which is responsible for most of the damage caused.
The larva sucks fluid from the plant cells, mainly from the leaves. The first symptoms include a strong discoloration of the leaf, leaving it almost transparent, and the appearance of black spots (caused by fecal secretions).
Its comb-shaped mouthparts scrape the tissues, making a soup with them that it will later suck. Click here to read the full article
The symptoms that the plant will show as indicators of the appearance of the mold fly are sudden wilting, a loss of vigor, poor growth and yellowing of the leaves.
When it comes to severe infections, a considerable portion of the plant can be lost. Click here to read the full article
Direct damage is caused to the plant in the whitefly feeding process.
The areas where the insect sucks the sap become discolored and, in turn, transmit toxic substances to the phloem that will spread throughout the plant, giving rise to metabolic imbalances, general weakening, chlorosis and changes in flowers and fruits. Click here to read the full article
Aphids feed on phloem sap, causing an imbalance in the plant's metabolism that leads to twisting of the leaves and, in extreme cases, their loss, which will affect the final quantity and quality of the plant. harvest. In addition, aphids introduce toxins into the plant, systemically altering its development.
On the other hand, the honeydew secreted by aphids is an ideal medium for the development of a wide variety of fungi, which will form a barrier on the leaf preventing it from absorbing all the light that reaches it. Click here to read the full article
The name mealybug derives from the fact that from their third larval stage onwards the females are covered in a white waxy substance.
Adult females have a soft, flattened, oval-shaped body. They can be pinkish in color, but are usually white, due to the whitish waxy powder that covers their body.
Equally waxy filaments emerge from all around their bodies. The male is a small, fly-like pulled insect that is rarely seen. Click here to read the full article
They prefer cold weather conditions, need humidity and come in a wide range of colors. Some of these springtails are known as “ snow fleas ” because they appear in early spring, when the snow begins to melt.
There are 4 major families in this group that have been found at extremely high population densities of more than 750 million individuals per hectare.
Although they are rarely considered a problem, they can be a problem when it comes to large populations developed in human habitats, but they will still need an organic food source and high levels of humidity to survive. Click here to read the full article
