Do you know when you will encounter pests during cannabis cultivation?
In the process of indoor marijuana cultivation, we must try to avoid plant contact with the outside, remove small flying insects indoors, prevent them from spreading harmful organisms and harmful bacteria, and disinfect the animals and plants that enter the planting environment. In the process of planting, due to other microorganisms in nature and environmental changes, coupled with the resistance of the hemp variety itself, it is difficult for a well-grown hemp to infect pests or harmful bacteria.
But many part-time farmers use half-corn and half-indoor methods to grow marijuana, let it out when the sun is good, and take it back indoors when the temperature drops. This method is low cost and does not consume too much heat. However, the growth rate and yield are fortunately simple, cheap and easy to operate. Some self-flowering varieties can adapt to this method and can produce good results.
Using this method has a big disadvantage-the invasion of parasites and harmful bacteria. Spread planting provides opportunities for invasion, and indoor planting provides a breeding ground. Once the indoor planting environment is contaminated, it is difficult to clean up. Before planting cannabis, you must know the appearance of various harmful parasites and harmful flora, and know the solutions, especially when you use this semi-greenhouse and semi-indoor planting method.
The focus of removing pests and diseases is prevention, which is to provide a healthy and harmless environment. Frequent observation of your plants, timely detection of pests and diseases is also the key point of management.
The following are common pests and harmful bacteria for growing hemp:
- Barnacles or scale insects
- Wide formaldehyde and gibberellin
- Bud rot or mold
- Caterpillars and loopers
- Flour mosquito
- Leaf miner
- Leaf Spot or Macular Disease
- Root rot
- Spider mite
- Tobacco mosaic virus
- White powdery mold
When your marijuana plant shows yellowing and whitishness, it is mostly because of these pests and flora.
Detailed explanation of common pests and bacteria in weed growing
This kind of insects mostly live on the north side of leaves, their larvae will eat leaves, and adults will grow wings to reproduce on the surface of other leaves.
Barnacles or scale insects
Such a bug looks like a small bag, sticking to the stem and leaves. They eat plants in large quantities and secrete body fluids that kill plants.
Wide formaldehyde and gibberellin
This is a very small mite, invisible to the naked eye. When the new leaves of the plant are bubbly, the branches and leaves are twisted, and the whole plant glows shiny. Flowering buds will quickly turn brown, and the plant will become thin and grow poorly. This shows that your plants are infected with this parasite, which is often mistaken for nutritional deficiencies, heat stress, or low pH.
Bud rot or mold
When this plant encounters mold attack, mold is universal in the world, in warm, dark, close, and oxygen-containing conditions. In a low-volume, windless space, there will be a large number of growths, depriving plants of nutrients and killing plants.
Caterpillars and loopers
Everyone should have seen this kind of bug, this kind of bug squirming between branches and leaves, eating plants.
Common diseases and insect pests, penetrating in body shape, will emit pleasant screams and gnaw the leaves of plants.
The tiny mosquitoes themselves will suck the body fluids of plants, which is not a big problem, and they will carry a lot of harmful fungi. It lays eggs near the plant, and the larvae crawl in the soil to increase the spread of harmful particles.
It is scale insects, which are the most common pests and diseases in the world. The size is larger than the size of crickets and crickets, and it has a stronger attack ability.
White spots, slow movement, and not obvious differentiation of body parts, it is difficult to grind it to be a bug. They will suck the liquid in the branches and leaves, causing them to die.
It looks like water stains on the leaves, but it is actually the holes left by this kind of bugs gnawing through the branches and leaves.
Leaf Spot or Macular Disease
There are uneven spots on the branches and leaves, yellow or brown, and uneven distribution on the whole plant. This disease is often mistaken for a lack of nitrogen or iron, but this uneven distribution reveals that it is a pest, not a lack of nutrients.
Looking at a hairy white tuo, crawling on the leaves and nibbling. The secreted body fluids will wither the branches and leaves.
A common killer in cannabis cultivation. Soil culture shows that plants suddenly stop growing and die slowly. Hydroponics shows that the culture medium turns yellowish brown, smelly and sticky. Is caused by plant diseases. Death or deformity.
Also known as snails, reorganization will eat the roots, stems and leaves of plants, but the reorganization will loosen the soil and strengthen the air permeability of the soil. The body fluids secreted will promote the growth of some beneficial bacteria. The small stir fry, the big braised.
The most common cannabis pest, a type of mite, is like white dust or scattered paint drips. Parasitic on the whole body of marijuana.
It looks like a lack of chlorophyll, but the whitish and irregular spots are very unevenly distributed. If you look closely, you can find wriggling white bugs.
Tobacco mosaic virus
Bacteria commonly found in tobacco cause the regional, asymmetric yellowing of cannabis leaves.
Tiny pink-white bugs. Strong reproductive ability and strong transmission ability.
White powdery mold
It looked like some white powder ash was sprinkled on the plants.
To prevent these pests, prevention is always better than treatment. Preventing foreign objects from polluting the planting environment and giving plants a suitable growth environment is always the most effective means of prevention and control. When the plant is not acting right, don’t worry about applying fertilizer. Observe carefully. It is very likely that the abnormality is caused by these pests. Must prescribe the right medicine!
