HOW TO USE THIS BOOK

This book is intended for people with cancer who cultivate and consume cannabis for therapeutic purposes.

The identification key allows the rapid and precise diagnosis of diseases, deficiencies and pests that have appeared on your crops.

The diagnosis is made through three steps:

* The first step is to select the infected part of the plant.

* The second step consists in choosing the symptom observed on the previously selected part. In order to avoid confusion during this step, the identification key focuses only on the symptoms that distinguish each disease without taking into consideration the ones that are commonly found in several diseases.

* The final step is to consult the disease page of the chosen symptom. This page includes:

- The name of the disease.

- A detailed description of the symptoms of the   disease.

- The causes of the disease (causal agent, favorable conditions, sources of contamination, dispersing agents, etc.)

- The means of control (cultural, chemical, biological, etc.) that allow to eradicate the disease and to prevent its futuristic reappearance.

IDENTIFICATION KEY

On leaves

- Fusarium wilt: Appearance of small irregular dark spots on older leaves close to the ground. The leaves turn yellow, curl up then wilt but remain attached to the plant.

- Powdery mildew: Appearance of mealy spots on the upper surface of the leaves. Subsequently, the entire surface of the leaf is covered with a gray white powder. As the disease progresses, growth is slowed down and the leaves turn yellow.

- Leaf septoria: Appearance of small round yellow, white, gray or brown spots. The spots sometimes have reddish-brown perimeters. The infected tissue dries up and falls off, leading to holes in the leaves.

- Downy mildew: Appearance of yellowish-white spots on the upper surface of the leaves. Meanwhile, pale spots and a gray mycelium could be observed on the back of leaves too.

––––––––

- Phosphorus deficiency: The lower (older) leaves are undersized dark green with purple / black spots. Affected leaves turn brown then curl downward and die.

- Potassium deficiency: The older leaves are initially chlorotic and develop dark necrotic lesions (dead tissue). This is primarily visible on the tips and edges of the leaves, then the disease progresses to the whole leaf.

- Magnesium deficiency:  Small rusty necrotic spots and / or interveinal-chlorosis appear in the lower (older) leaves. However, the veins remain somehow green and the edges of the leaves curve upwards

- Sooty mold:  A black coating reminiscent of chimney soot develops on the leaves.

- Calcium deficiency: The large leaves at the top of the plant are affected. The initial symptom is the appearance of yellow-brown spots surrounded by a brown border. Later, growth is slowed down and production declines.

- Iron deficiency: Interveinal chlorosis of young leaflets starts to develop at their base and reaches their tip. The veins remain green and thus contrast with the interveinal tissues. Chlorosis can affect the whole plant.

- Nitrogen deficiency: The lower leaves turn into pale green, then yellow before dying. The stems and undersides of the leaves may turn into purplish red. Symptoms spread upwards, affecting all the main leaves then the smaller and younger leaves as well.

- Aphids: Small pear-shaped insects  (2-3 mm) which can have several colors (black, green, pink, yellow, etc). Their posterior end is prolonged by a pair of cornicles resembling to nozzles. These insects can be winged or wingless.

- Whiteflies: Small fly (1/16 inch in length) with wings covered with white wax. These insects feed and lay their eggs on the undersides of young leaves, where they fly away at the slightest disturbance.

- Thrips: Appearance of tiny white or silver spots on the foliage.

- Thrips: Tiny parasitic insects with elongated  and flabby bodies; they are yellow, black, or brown, less than 3 mm (0.12 in) long, and about the width of a pencil lead.

- Red spider mit: Presence of fine webs woven around the leaves and stems of the plant. These webs are not visible, but when water is sprayed on the plant, they become very noticeable.

––––––––

-  Red spider mite: The appearance of tiny yellowish or whitish punctiform spots, mainly around the central vein or the widest veins on the leaf. When these spots become too numerous, the entire leaves turn yellow, dry out, and fall off.
