[QUOTE="L0oD, post: 419348, member: 42867"] Pests-Bugs-Virus Unfortunately, bugs or pests can totally mess up your marijuana harvest. Some bugs live in soil, while other pests are airborne. Mold can be a big problem too.But you don't have to sit back and take it. This page aims to be a comprehensive resource on the different types of bugs / pests / mold that can affect your marijuana crop, along with tips for preventing and solving each problem. [ATTACH]55108[/ATTACH] Pests that can affect your marijuana plants include aphids, spider mites, ants, whiteflies,white powdery mildew / white powdery mold, stem rot, and even mammals such as gophers and rats. It's time to fight back against cannabis bugs, mold and pests! Aphids [ATTACH=full]55109[/ATTACH] Aphids are soft-bodied insects which can be green, yellow, black, brown or red. They are usually small and oval-shaped, and may have dicernable wings or antennae. Aphids use their piercing, sucking mouth-parts to feed on the sap of plants and usually occur in colonies located on the undersides of stems or leaves. If a plant becomes heavily-infested, its leaves can turn yellor or wilt due to the excessive sap removal. Aphids produce large amounts of a substance known as "hondeydew," a sugary liquid waste. Honeydew drops from these insects and can causes spots on the windows and finish of cars which are parked under infested plants. A fungus called sooty mold can grow on honeydew deposits which accumulate on the leaves and branches of your plant, turning them black. Many times, an aphid infestation is only noticed after the first appearance of sooty mold. The drops of sweet honeydew can also attract other insects such as ants. An infestations is generally the result of a small numbers of winged aphids that fly to the plant and take it up as their new host. Winged aphids deposit several wingless young on the tender undersides of leaves/steams before moving on to find a new plant.[ATTACH=full]55110[/ATTACH] Immature aphids, or nymphs, that are left behind, feed on plant sap and increase gradually in size. They mature in 7 to 10 days and then are ready to produce live young. Usually,all of them are females and each is capable of producing 40 to 60 offspring. The process is repeated several times, resulting in a tremendous population explosions.Less than a dozen aphid "colonizers" can produce hundreds to thousands of aphids on a plant in a few weeks.Aphid numbers can build until conditions are so crowded, or the plant is so stressed, that winged forms are produced. These winged forms fly off in search of new hosts and the process is repeated. Solution: Early detection is the key to reducing aphid infestations. The flight of winged colonizers cannot be predicted, so weekly examination of plants will help to determine the need for control. Examine the bud area and undersides of the new leaves for clusters or colonies of small aphids.The presence of these colonies indicates that the aphids are established on the plants and their numbers will begin to increase rapidly. Fatty acid salts or insecticidal soaps are very good against aphids. They apparently work to disrupt insect cell membranes. They require direct contact with the insects and leave no residual effect. Nervous system insecticides, such as malathion, Dursban (chlorpyrifos), and Orthene (acephate),are labeled for use on many shade trees and ornamental plants for aphid control. As with soaps, coverage is very important and a follow-up application may be necessary. Sevin (carbaryl) is not effective against many aphids so it is generally not a good choice for control unless recommended specifically.In fact, applications of Sevin may reduce the number of beneficial insects, such as lady beetles, and increase the potential for aphid outbreaks. Beneficial insects, such as lady beetles, lady bugs, and lacewings may eat large numbers of aphids but the reproductive capability of aphids is so great that the impact of the natural enemies may not be enough keep these insects at or below acceptable levels. To keep aphids and other pests off your plants just finely chop1 onion and 2 medium cloves of garlic.Put ingredients into a blender with 2 cups of water and blend on high. Strain out pulp.Pour liquid into spray bottle. Spray a fine mist on plants, making sure to coat both tops and bottoms of leaves. Caterpillars, Inchworms & Cabbage Loopers Caterpillars, Inchworms & Cabbage Loopers Caterpillars!!! Argh!!!

Spinosad products are organic and completely harmless to pets, children, and plants.

Leaves begin to yellow and start getting what appears to be nutrient deficiencies. Learn How to Prevent & Get Rid of Root Rot! Slugs/Snails The common slug is too common a pest to even need much of an introduction. Slugs attack a wide range of plants, causing anything from slight damage to death. [ATTACH=full]55118[/ATTACH] Unfortunately, these annoying pests attack leaves AND buds, and they can do a surprising amount of damage in a short time, so you want to watch out for them and get rid of them quickly. They often stay hidden, attacking your plants at night, so stay vigilent for slug and snail damage! Solution: There is no foolproof method for eradicating slugs. How to Make Beer Trap for Slugs and Snails: mix flour with some stale beer and use it to fill a shallow container. Place in garden with the rim 1 or 2 cm above the ground so that slugs and snails can climb in. Substitute beer for wine, sugar water, juice, or water mixed with yeast. BE WARNED, the trap will fill up quickly so come back often to empty. To be sure you're keeping your slimy slug population under control; collect them by hand at night or on damp days. Try collecting them under a tile or wet cardboard, and squash all eggs you find while digging.Placing a saucer of salt is another method that will kill snails and slugs. Martha Stewart recommends coiling a piece of wire around the base of your plants to give slugs a shocking experience. Thrips Thrips are small, fast-moving insects with wings. They suck the good stuff out of leaves, and prefer to munch on flowering tops and young, tender foliage.Leaves that have been attacked by thrips have shiny, silvery spots where they were bitten. In spite of the fact that thrips are very small, they're relatively easy to spot so you can see them marching in columns on an infested plant. Here's a picture of a thrip on a finger for scale - they're tiny! [ATTACH=full]55119[/ATTACH] Recommeded: Monterey Garden Insect Spray with Spinosad to kill them... Tobacco Mosaic Virus The tobacco mosaic virus can attack a wide range of plants, including tomato, pepper, eggplant, tobacco,spinach, petunia, marigold, and our beloved herb marijuana. On marijuana the virus infection causes light and dark green mottled areas on the leaves. The dark green areas tend to be somewhat thicker than the lighter portions of the leaf. The leaf mottling is seen more easily if the affected plant surface is partially shaded. [ATTACH=full]55120[/ATTACH] Stunting of young plants is common and often is accompanied by a distortion and fern-like appearance of the leaves. Older leaves curl downward and may be slightly distorted. Certain strains of the virus can cause a mottling, streaking and necrosis of the buds. Infected plants are not killed, but they produce poor quality buds and low yields. Tobacco mosaic, is incited by a virus. The tobacco mosaic virus is very stable and can persist in contaminated soil, in infected plant debris, on or in the seed coat, and in manufactured tobacco products. The virus is transmitted readily from plant to plant by mechanical means. Solution: Virus diseases cannot be controlled once the plant is infected. Therefore, every effort should be made to prevent introduction of virus diseases into the garden. Sanitation and cleanliness is the primary means of controlling virus diseases. Infected plants should be removed immediately to prevent spread of the pathogens. The use of tobacco products during cultural practices should be avoided to prevent inoculation of plants with the tobacco mosaic virus. Those people using tobacco or working with infected plant material should wash their hands thoroughly in soapy water before handling your plants. This may simply involve picking up the virus while working with infected plant material,then inoculating healthy plants by rubbing or brushing against them with contaminated tools, clothing, or hands. Aphids are not vectors of the virus, although certain chewing insects may transmit the pathogen. White Flies / Whitefly White flies behave just like spider mites. The insect hides underneath the leaf, punctures the eaf and sucks up the essential nutrients from the plant. This results in white spots on the top side of the leaf. White flies are easily spotted with the naked eye. If you shake the plant a little, they'll fly around.They look like little white moths, around 2 millimeters in size. [ATTACH=full]55121[/ATTACH] Bleach solution (1 tablespoon of bleach to 1 gallon of pH balanced, water in a spray bottle or mister) -make sure to clean all surfaces of your room, and bleach them too if possible. Alcohol and Water mixed togther will also kill the bugs on contact and shouldn't hurt the plant as long as the solution contains at least 40% water. You will want to use a spray bottle or mister. SM-90 (Safe & Organic) mixed with water (1 part SM-90 to 5 parts water) kills whiteflies on contact and is organic (it even smells good!). You will need a mister to get nice even coverage on all the leaves with SM-90. Neem Oil works in a similar way to SM-90, though Neem oil doesn't smell as nice and will leave an unpleasant taste/smell on buds when used to treat flowering plants. There's some evidence Neem oil may be harmful to humans so use with care! Just as with SM-90, you will need a mister to get all the leaves evenly,especially since neem oil and water will separate easily.
