Here are some types of bugs/pests that can affect your cannabis crop, along with tips for preventing and solving each problem.
Aphids:
Aphids are soft-bodied insects, which can be green, yellow, black, brown or red. They are usually small and oval, and can be discernible wings or antennae. Aphids used for piercing mouth parts and feed by sucking the sap of plants occur, the colonies are found in stems or undersides of leaves. If an institution becomes strong, its leaves can wilt or turn yellow because excessive sap removal.
Solution: Early detection is key to reducing aphid infestations. Vanishing winged colonizers can not be predicted, then the weekly review of plants will determine the need for control. tender area and examine the underside of the leaves of new clusters or colonies of small aphids. The presence of these colonies showed that the aphids are established on the plants and their numbers began to increase rapidly. fatty acid salts or insecticidal soaps are very good against aphids.
White flies:
White flies behave just like spider mites. insects hiding under the leaves and sucks him dinner. Resulting in white patches on the upper surface of the sheet. Whiteflies are easily identifiable to the naked eye. If you shake the plant a little, they will fly around. They look like tiny white moths, around 2 millimeters.
Solution: A problem of whitefly can be solved by misting your plants in a solution of 1 part SM90, 5 parts of water. When you spray the plants and make sure you get the following (this is where they lay eggs). You want to do when the lights are out (otherwise the leaves will burn.)
Thrips:
Thrips are tiny insects with wings faster. The rasp, or marijuana gate opens to suck the juice. Thrips prefer flowering tops, and fresh young leaves. Affected leaves are shiny, silver spots. This is caused by thrips suck the chlorophyll in leaves. Although they are small, you can see them walking in columns on an infested plant.
Solution: Thrips can be prevented favorite insecticide. O predatory insects, thrips natural ‘enemy Amblyseius cucumeris.
Lice:
Lice are found inside and outside. And thrive in the summer. Lice are more concerned with questionable sanitation.
Solution: There are two methods to kill lice, spraying with insecticides, and define Assassinator wasps. The problem with most flying predators is that they are attracted to lights at high gas pressure that we all love to use that sends most of them for a quick and fiery death.
Snails/Slugs:
The common slug is too common a pest introduction is still a lot. Slugs attack a wide variety of plants, causing some slight damage to death.
Solution: Unfortunately, there is no foolproof method for eliminating snails. All you can hope for is to reduce their number and to protect the plants when they are both vulnerable. Toads, frogs and insects eat slugs and should be encouraged in your garden. One of the best ways of dealing with slugs is to use physical barriers. Place plastic bottle bells around plants, or sprinkle the circles of lime, eggshells, or sawdust around plants. Snails are attracted to saucers or plastic pots of milk or beer (they drown in ecstasy). To be sure to keep your slimy slug population under control, collection by hand during the night or on wet days. Try to gather under a tile or wet cardboard, and squash all eggs you find while digging. Place a platter of salt is another method that is as old as the hills. Martha Stewart recommends coiling a wire around the base of your plants to give slugs a shocking experience.
Pythium root rot:
Pythium root rot can be caused by several species of Pythium. These fungi are common in soil, sand or sediment of surface water and dead roots from previous crops. Pythium was also found in some soilless commercially available potting mixes. Pythium is easily introduced into pasteurized soil or soilless mixes by using dirty tools, dirty pots or flats, or walk to allow pets for a walk in the mixture and mix by dumping on the banks of potted plants or not have been cleaned thoroughly. When introduced into pasteurized soil or soilless mixes, Pythium can cause severe root rot because it has few competitors to check its activity. This fungus is a threat to crops in hydroponic systems. If the tank is heavily contaminated with debris or soil Pythium housing, the fungus can spread to a large number of plants quickly. If the fungus infests a cutting bed or if contaminated water is used in the spread, usually produce large losses.
Solution: rodbrand Pythium is difficult to control once it begins. Everything should be on preventing disease before it starts. pasteurized soil and sand with heat (microwave) or chemical treatments disinfectants. If water is suspected to be the main source of Pythium, it may be necessary to treat water before use. Slow sand filtration has proven to be an effective, simple and inexpensive to remove water Pythium. Cover the treated soil and keep it or soilless mix in an area that will not be contaminated by the introduction of untreated soil. also covers flows and reservoir drainage system. Disinfect all surfaces, tools and equipment to make contact with this mixture. We also found that hydrogen peroxide (H2O2) is ideal for control of Pythium in both soil and hydro.
Almost all plants are susceptible to root rot and Pythium. roots that are very important in making nutrients and water are attacked and killed. Pythium can also rot the stem base. Pythium symptoms are plants stunted, the roots are brown and yellow and dead plants die, the plant in mid-day and may recover at night, the decline may continue until the mother, brown adipose tissue on the outside of the root is easily separated out leaving a little exposed bare vascular tissue, and root cells contain thousands of microscopic spores thick-walled.
