The Cannabis cultivation, known for its delicacy and its specific needs, faces various challenges, being one of the most significant the infestation of the red spider (Tetranychus Urticae). This tiny plague, often imperceptible to the naked eye, can wreak havoc on the plantations, becoming an obstacle to rookie and experienced cultivators equally. The red spider, characterized by its coloration that varies from pale yellow to the dark red, feeds on the cellular content of the leaves, leaving behind a trace of damage and weakness in the plants.
The impact of the red spider on cannabis cultivation is not less. These mites not only decrease the aesthetic vitality and general health of plants, but also compromise their ability to develop quality flowers. The decrease in productivity and cannabis quality can be considerable, making the effective control of this plague imperative.
Therefore, understand how to combat the red spider and how to eliminate the red spider definitely and learn about the available red spider treatment options, including insecticides and specific red spider, both homemade and commercial, becomes crucial. We will explore various strategies and treatments to handle this plague, thus guaranteeing the optimal health and productivity of your cannabis crops.
Identification of the red spider in cannabis plants
The red spider, a silent enemy in cannabis cultivation, can be difficult to detect due to its tiny size and their ability to hide. However, knowing its appearance and common symptoms that it causes in plants is essential for effective control.
Description of the appearance of the red spider
The adult red spider measures approximately 0.5 mm, which makes it almost invisible to the naked eye. They are often identified by their color, which can vary from a pale yellow to a dark red, depending on factors such as species and environmental conditions. These mites are usually found in the lower part of the leaves, where they weave fine cobwebs that are a clear indicative of their presence.
Common symptoms in affected cannabis plants
Cannabis plants infested by the red spider show several symptoms, including:
- Yellow or whitish points: They appear on the leaves due to cell damage caused by mites feed.
- Withered or deformed sheets: The general health of the leaf deteriorates as mites continue to feed.
- Thin web: Mainly at the bottom of the leaves and between the shoots.
- Reduction of the general vigor of the plant: Affected plants usually show a slower growth and lower flower production.
Tips for early detection
- Regular inspection: Examine your plants frequently, paying special attention to the lower part of the leaves and new outbreaks.
- Use of a magnifying glass: Given the small scale of these mites, the use of a magnifying glass can be crucial for early detection.
- Environmental monitoring: The red spider thrives in heat and low humidity conditions. Keep a climate control in your cultivation area to prevent infestations.
- Attention to the first signs: At the first indication of yellow or web points, act quickly to confirm the presence of the red spider.
Conditions that favor the infestation of the red spider
The red spider is not only one of the pests and diseases in marijuana more common, but also one of the most challenging to control. Its appearance and proliferation are closely linked to certain environmental conditions. Understanding these factors is vital to implement preventive and control strategies.
Environmental factors that promote its appearance and proliferation
- High temperature: The red spider thrives in warm environments. Temperatures between 26 ° C and 30 ° C favor their rapid development and reproduction.
- Low moisture: These mites prefer dry environments. A low relative humidity is ideal for survival and growth.
- Inadequate ventilation: The lack of good air circulation can create microclimates that favor the infestation of the red spider.
- Stressed crops: Weakened or stressed plants by other factors (such as inappropriate irrigation or nutritional deficiencies) are more likely to be attacked.
Importance of constant monitoring in different stages of cannabis growth
- Germination and seedlings: During the early stages, plants are particularly vulnerable. It is crucial to maintain optimal conditions to avoid stress that attracts mites.
- Vegetative stage: As plants grow, the surface available for the red spider increases. Regularly monitors to detect the first signs of infestation.
- Flowering stage: This critical stage requires even more rigorous surveillance. The red spider can cause significant damage to the buds, directly affecting the quality and performance of cannabis.
- Harvest and cured: Although less common, it is important to ensure that plants are pest -free before proceeding to these final stages.
Prevention methods
Prevention is always the best strategy in pest management, especially in the case of the red spider in cannabis crops. Implementing adequate cultivation practices and preventive strategies can significantly reduce the risk of infestation.
Strategies to prevent the appearance of the red spider
- Environmental control: Keep a culture environment with moderate temperatures and proper relative humidity. Avoid conditions that favor the development of the red spider, such as excessive heat and low humidity and knows At what temperature the red spider dies.
- Adequate ventilation: Make sure your cultivation space has a good air circulation. This not only prevents the appearance of favorable microclimates for mites, but also strengthens plants.
- Cultivation hygiene: Clean and regularly disinfect your culture area, including tools and surfaces. Avoid the introduction of pests through contaminated plants or substrates.
- Biological control: It uses natural enemies of the red spider, such as predatory mites (Phytoseiulus persimilis), as a preventive control method.
Recommended culture practices to reduce the risk of infestation
- Routine inspection: Examine your plants regularly in search of early infestation signs. Pay special attention to the bottom of the leaves.
- Plant stress management: Keep your plants healthy and without stress, since weak plants are more susceptible to pests. This includes adequate irrigation, balanced nutrition and disease prevention.
- Use of physical barriers: Implements physical barriers, such as fine meshes, to protect external intruder plants.
- Crop diversification: The diversification of plants in your garden can help prevent the spread of the red spider, since some plants can act as natural repellent or attract beneficial predators.
Chemical solutions: When and how to use them
Although organic methods are preferred by many, in certain situations, especially in cases of severe red spider infestations, the use of chemical solutions may be necessary. Every cultivator must know how to eliminate the red spider from cannabis plants and choosing the proper insecticide and applying it safely and effectively is crucial to control the plague without causing additional damage to the plants or the environment.
Information on Effective Chemical Insecticides
- Red spider stroke: Products specifically designed to combat mites, such as red spider. These may be more effective than general insecticides.
- Pyrethroids: Chemical compounds that act on the nervous system of mites. However, its use must be handled carefully due to its possible toxicity and resistance.
- Horticulture oil insecticides: Although less aggressive than other chemicals, they can be effective in the control of mites when used correctly.
- Systemic insecticides: These products are absorbed by the plant and can be effective against pests that feed on it, such as the red spider.
Tips for safe and effective use, minimizing the impact on the plant and the environment
- Read and follow the instructions: Before applying any insecticide, read carefully the instructions and follows to the letter.
- Proper dose: Apply the recommended amount. Excessive use can damage plants and contribute to plague resistance.
- Careful application: Avoid sprinkling on winds or high temperatures to reduce drift and volatilization.
- Product rotation: Alternate between different types of insecticides to prevent the resistance of the red spider.
- Personal protection: Use adequate protection equipment during application to avoid exposure to chemical substances.
