This can vary depending on your geographical location or the climate. Become familiar with the types of pests present in your area to help you identify which ones are causing your issue. You will need to know the specific insects because many insecticides are only effective against certain types of pests. For instance, the grape berry moth is a common pest found in the northeastern United States. The insecticides Intrepid or Sevin are rated as highly effective in controlling them, but Assail is not effective at all. Assail is effective, though, in controlling leafhoppers, which are prominent pests in California and the western United States. You will need to read the labels to be sure you get the right product. For instance, if you've determined that your insect problem is from the grape berry moth, you will need a product that specifically states that it is effective in controlling grape berry moths. Some products, like Home Orchard Spray, aim to control a variety of common grape vine pests including the grape berry moth, Japanese beetle, and rose chafers. A broad-scope product may be a good option if you have multiple types of pests and/or haven't been able to identify the specific type of insect affecting your vines. Pesticides typically range from $10.00 - $20.00 USD and can be purchased as a concentrate that needs to be mixed with water, or as a ready-to-use spray. Read the label thoroughly before you use a pesticide. Wear gloves and goggles while you spray so you don't come into contact with any chemicals. Some pesticides are not safe for consumption so make sure to follow the label directions. Don't let pets or people near grapes you've sprayed until the amount of time passes as recommended. There are many organic pesticides that contain neem oil. The products are available as a dust, wettable powder, or a concentrate to be mixed with water. Check online or at your local home and garden store to find a product that fits your needs. Neem oil should not be applied to table grapes after they have bloomed, so apply it to the vines early in the season for the best results. Follow the instructions on the label. Some products require certain temperatures to be effective, a waiting period before the grapes can be consumed, and some should only be applied during certain growing stagesfor instance, not when the fruit is blossoming. Reapply the pesticide as needed and as directed on the product label. Be sure to wear protective gear like gloves and safety glasses when applying chemicals.

There are a couple of different ways to write and deliver jokes including the traditional set up and punchline, one-liners, or short stories. One liners can be an extremely effective format. Comedian BJ Novak made the simple and effective, if tasteless, one-liner: "Battered women: sounds delicious." Novak's joke plays on two elements you can incorporate into your material: surprise and twisting word meanings. It's also a traditional set up and punchline type of joke. Jokes as a short story are another effective method. However, remember to keep them short! A good example of a joke wrapped in a short story is: "There was once a young man who, in his youth, professed a desire to become a "great" writer. When asked to define "great" he said "I want to write stuff that the whole world will read, stuff that people will react to on a truly emotional level, stuff that will make them scream, cry, wail, howl in pain, desperation, and anger!" He now works for Microsoft writing error messages." Every joke, no matter what structure you use, has a set up and a punchline. The set up and punchline will sometimes contain elements of surprise based on assumptions, twisting words, or playing on ironies. Remember "less is more." As you prepare your set up and punchline, remember that you will want to tell your joke in as few words as possible. Avoid unnecessary details and phrases. BJ Novak's joke "Battered women: sounds delicious" and the joke "What did the cake say to the knife? You wanna piece of me?" are examples of jokes that demonstrate the "less is more" strategy. Any other details would have caused the jokes to fall flat. Your set up should be one or two lines, or a few lines for a story. It prepares your audience by creating an expectation and giving them the details they need to understand the punchline. The joke about the dead cactus is a good example of this. The comedian sets up the joke with the lines "I bought a cactus. A week later it died." The punchline is the "funny" part of your joke that will make people laugh. It builds on the set up and is only one word or one sentence. It often reveals the surprise, irony, or word play to your audience. Again, the dead cactus joke is a good example of a short and funny punchline. After setting up the audience with the details of his plant cactus, the comedian tells us: And I got depressed, because I thought, Damn. I am less nurturing than a desert." ." Elements such as familiarity, exaggeration, and irony will enhance your joke. A good example of exaggeration and irony is the story about the young man with great aspirations. Most listeners will expect that he fulfilled his wish to write "stuff that people will react to on a truly emotional level, stuff that will make them scream, cry, wail, howl in pain, desperation, and anger!" through novels or short stories. Instead, the surprise is that "He now works for Microsoft writing error messages." Tags and toppers are additional punchlines that build upon your first punchline. You can use tags and toppers as a way to get extra laughs without writing a new joke or needing to set up any material. For example, you could add a topper to the short story by saying "In fact, he's the one screaming, crying, wailing, and howling in pain the most." Before you tell your joke to friends or any audience, practice delivering it. You'll need to find the joke funny for your audience to feel the same! If you don't find the joke funny or somehow off, revise it until it works for you.
