RED SPIDER: HOW TO FIGHT THIS PEST

Confronting pests such as the spider mite in a cannabis plantation or cultivation should not be alarming. It is true that it is a nuisance that can create great inconveniences and even lead to the loss of the plantation , but if you know well how to combat the spider mite, there should be no problem.

As in all cases related to the cultivation of marijuana, the main thing is to know how to identify the problem, carry out regular inspections in the plant and act on any clue that may determine that we are facing a plague and eliminate the red spider immediately.

WHY DOES THE RED SPIDER APPEAR IN OUR CULTURE

The fact that spider mites appear on marijuana plants does not necessarily mean that something wrong is being done. This is one of the most frequent pests in the cannabis plant and appears both in indoor crops and in outdoor plantations.

The spider mite is a tiny mite that affects plants and its appearance has as a consequence a significant decrease in production and harvest. It is reddish or brown in color (hence its name) and is usually found in the lower part of the leaves , where they are protected from external elements that could put their life at risk.

It is a presence that reproduces very quickly and that is capable of moving from one plant to another with an amazing speed , so that it requires the elimination of the spider mite immediately once it has been located.

And how does it get to our marijuana plants? It generally arrives by moving from other plants in the garden or nearby areas, which is why it is a common pest, especially outdoors. In addition, they have a preference for unclean, poorly ventilated and especially humid and warm crops.

What they do on plants is very different from the action of other types of pests; This makes identifying the presence of spider mites not particularly complex : these mites produce small ‘pecks’ on the leaves, which are subtly yellowing . As a consequence, marijuana generates a stress situation, loses leaves and even stops its growth, which undoubtedly has clearly negative effects on production and harvest.

HOW TO ELIMINATE SPIDER MITES FROM OUR CROPS

The best way to fight the spider mite infestation is good prevention. Preventing them from reaching the cultivation is the best measure so that cannabis does not suffer. This is achieved by limiting the use of nitrogen fertilizers , generating good ventilation if the crop is indoors or by perfectly controlling the humidity so that it is as low as possible, within what is recommended for the growth of marijuana.

In the case of being faced with the attack of a plague, eliminating the spider mite generally involves the use of chemicals such as potassium soap or other products that are applied by nebulization: biological insecticides or acaricides of proven effectiveness that kill the mites without harming the plant growth and health.
