When it comes to growing our marijuana plants, we are always attentive to see how the buds evolve, their aroma and more. Now, what happens when we run into bugs or pests in our plant. In the following article we want to give you information about the most common pests that can attack your plant and the insecticides and fungicides that we have in Flor Prohibida to be able to solve them.
Pests that can attack your marijuana crop and how to combat them
Among the most common pests we find:
Red spider. It is one of the scariest pests that attacks our crops. It appears many times in plants grown in dry and indoor environments, and then disappears with the arrival of cold.
White fly. This plague is reproduces very fast and can spread throughout your crop in just a few days stopping the activity of the plant. It is a very small flying insect that hides under the leaves where it lays its eggs. The main cause of its appearance is high temperatures and certain humidity, both indoors and outdoors.
Aphid. This pest reproduces very fast, attracting even ants and other insects due to the honeydew it gives off. They are responsible for absorbing the fluids of the plants causing them to wither and yellow. In addition, aphids can carry other viruses, such as fungi and bacteria.
Trips. It is one of the most common pests in cannabis cultivation. They appear when the climate reaches a warm temperature of 20-25 ºC and they dedicate themselves to gnawing the leaves and sucking the sap from them. In addition to all the phases that you go through that spread very easily, they can bring up to 20 different types of viruses in their mouth.
Minelayer. These worms are responsible for creating tunnels in the marijuana leaves, forming galleries and causing the deterioration, wilting and consequently the death of the leaf. They appear in hot climates and generally begin on the lower leaves where the female pierces and lays eggs.
Woodlouse. This insect loves colonize marijuana plants, sucking the sap and therefore delaying its growth, delaying its flowering and reducing production. In addition, the honeydew they secrete can cause fungal appearances such as Tizón and Negrilla.
To combat mites, the most important thing is to try to humidity is between 45 and 55% and that the temperature does not exceed 20º, in addition to increase circulation and apply a foliar irrigation. But if it is too late to avoid pests, you should make sure to eliminate them completely, that is why from Flor Prohibida we want to recommend the following acaricides to combat them.
How to eliminate flowering mites with insecticides?
Skunk 8CC. If what you are looking for in remove newly hatched eggs and mites, this insecticide is ideal. It is a specific contact acaricide that is less dangerous for us and for other beneficial “bugs” that may appear from your cultivation.
How to use: You should apply doses of 0.5-0.6 cc / L in foliar spray. In case you detect the presence of mobile forms, you can mix it with an authorized adulticide acaricide.
Belproil A. Ideal for combine it with the Skunk 8CC, since in this case we will attack the older pests. It is a paraffin concentrate that fights all types of mites, mealybugs, aphids and whiteflies, among others, and that acts by forming a layer on the leaf surface that ends up drowning the different mites.
We recommend that 30 minutes before applying the product, make a application of potassium soap to attack the exoskeleton of insects and mites, and thus facilitate the action of the insecticide or miticide to be used.
Sulfapron L SC: This is another insecticide that we can combine with Skunk 8C. In this case in addition to treating and preventing mites such as red spider mites, we will be able to combat diseases such as powdery mildew. Based on Sulfur (72%), it is a concentrated and self-emulsifying suspension that works through direct spraying on our marijuana plants.
How to use and dosage: We must mix 2 to 6 ml for each liter of water and spray directly on the leaves and the entire surface of the plant.
How to fight fungi like powdery mildew?
Powdery mildew is the main cause of white spots that appear on the leaves of plants. This pathogenic fungus attacks marijuana plants, grown both indoors and outdoors, when the powdery mildew fungus attacks the cannabis flower, This can no longer be used for consumption, because it can cause various health problems, especially in the lungs.
But don’t worry, we have the ideal insecticides to combat this fungus on your crops:
Lexor 25. This product belongs to chemical group of triazoles and its main component is Difenoconazole, which works by inhibiting the biosynthesis of ergosterol, a process necessary for the life of the fungus. Being a chemical fungicide you should not come into contact with it, or breathe it. In addition, you can also combat fungi such as alternaria or rust.
How to use and dosage: You should mix 0.3 – 0.4 ml for each liter of water and spray on the surface of the plants without coming into contact with the fungicide solution.
Belpron special fluid 80: This product is mainly composed of fluid micronized sulfur, a type of sulfur that thanks to its small size and weight allows it to be reach places that are difficult to access and cannot be reached by sprayers. You can also avoid botrytis, mildew and the appearance of the red spider.
How to use and dosage: It is applied by sprinkling on the surface of the plants and the soil, at a dosage of 20 to 30 grams per square meter. To get the best resultWe recommend applying it to a sublimator and leaving it with a frequency of use in preventive mode of 1 to 4h / night and in curative mode of 1 / 6h night (it is recommended to stop using it after 2 weeks),
Another ideal fungicide to combat powdery mildew is Sulfapron L SC.
Avoid future illnesses
In addition to powdery mildew, we can find other fungi harmful to our plants such as alternaria, mildew, rust, pythium or fusarium:
The alternaria it’s a pathogenic fungus that can grow in our cultivation if we are not careful. It is very aggressive and will progressively weaken our plant. This fungus travels through the air, soil and ponds, and although it can attack at all stages of your plant’s growth, it is most common during flowering and maturation. Produces necrotic spots, dry and circular, in addition to slow plant growth.
The rust is another fungal disease, which generally occurs on the leaves. This mushroom is caused by spores that travel in the wind and they can remain active for up to 50 days, making it very easy for it to spread. Once it manages to penetrate our plant, it multiplies very quickly. It produces in our plant some small reddish or brown bumps on the underside of the leaves, producing yellow spots or portions that are more discolored than with time. can leave our plant without leaves.
The Mildew it is a cryptogamic disease causing those white or yellow spots somewhat translucent that we find in the upper part of the marijuana leaves. Unlike powdery mildew, when it is advanced, they will end up staining the leaves brown and necrotizing them.
The Pythium It is especially developed in seedbeds, indoor crops in greenhouses or in any unstable environment. Among its symptoms we find the growth retardation, mild foliar chlorosis, and brown root lesions which turn into root rot.
The Fusarium it’s a lethal fungus that can end the life of a plant in just a few hours. The fungus is spread by spores that usually form in the mycelium, very resistant and difficult to fight spores. The roots are affected with brown and / or white molds that end up rotting, in addition to altering the circulation of the sap and the activity of the roots stops.
All these fungi are very aggressive for our plant, but do not worry, since Forbidden flower We bring you some ideal products to prevent them:
Fosvel 80PM. Ideal for both prevention and eradicate fungi such as Pythium, Downy mildew and Phytophthora. This fungicide for marijuana is very effective in the control and prevention of diseases thanks to its systemic action. This means that the plant absorbs it through a foliar irrigation and distributes it throughout it to keep it protected.
How to use and dosage: We must mix 2.5 to 3 grams for each liter of water and apply it by spraying on the surface of the plant. We recommend not repeating the treatment more than 3 times during the entire culture and waiting at least 15 days to use it again.
Olicobre 70 SC. This is a preventive fungicide that we can use domestically. It is composed of copper oxide with which you can prevent the appearance of fungi such as alternaria, rust or mildew. This works by spraying it on our plant and it will ensure that we do not have problems with this type of fungus.
How to use: Mix 1.5 ml of Olicobre for each liter of water and spray on the surface of the plants. Use since the plant has developed a few leaves and continue to do them every 10 days until the buds start to come out of the buds.
Probelte offers us a range of products suitable for agriculture and among them we find the Belproil A, a concentrate that, in addition to combating all types of mites, is authorized for organic farming.
It’s a highly effective product and will increase it even more when combined with products such as Bermectine to combat the spider mite and Beltasur 500 for winter treatments.
Beltasur 500. You can combine it with Belproil A to fight fungal diseases such as rotaria, rust and mildew. It is a wettable and micronized powder that is composed of copper oxychloride that shows excellent results.
The most important is to act quickly and above all use preventive treatments to prevent the fungus from entering the leaves, flowers, trunk, roots … The most efficient thing is to do treatments in times of risk As can be the rainy seasons when the flowers are already compact and the humidity is established between the buds and with the lack of ventilation between them it takes time to disappear, especially in the months of September, October and November.
