When to Spray
| EARLY SPRING (late Feb., early March, before green starts to show) |
| SPRAYING JOB | PESTS CONTROLLED | SPRAYERS TO USE |
| Pests overwinter on shrubs, trees, and other woody plants. A dormant spray stops many damaging insects before they have a chance to develop and infest new growth. | Scale, insects, mites, aphids, leaf curl, anthracnose, mealy bugs, hibernating caterpillars and various insect eggs. | High-pressure sprayer provides long-range spray to reach tops of 25-ft. trees. Can also be used for low-growing plants. For lower growing trees, shrubs, bushes and woody plants. Ideal for big jobs such as many fruit trees or plantings. Either gasoline or electrically driven, power sprayers can reach high into 25 to 30 ft. trees. |

| Apply herbicide either when weed is actively growing or before it emerges, depending on the weed. (Dandelions are best controlled with a post-emergence herbicide after they have appeared, while crabgrass is easier to stop before seeds sprout. This is done with a pre-emergence herbicide.) | Dandelions, crabgrass etc. | For average sized lawns. Adjust nozzle to a coarse spray. Spray weeds at low pressure to avoid drift. Spot spray weeds or protect entire lawn by moving spray pattern back and forth across lawn about 18" above the ground. Best for large lawns. |
| EARLY SUMMER |

| Keeping your garden clean will help prevent insect problems. Remove all weeds and dead plants. Check plants regularly for insect damage. Apply spray as needed. | Aphids, leafhoppers, Colorado potato beetles, lace bugs, thrips, cut worms, mites and many other pests. | Versatile; provides precise application and proper control. For small gardens: a 1 1/2- to 2-gal. size is recommended. For average to large gardens: a 3- or 4-gal. size is best. When a dust is preferred or recommended, apply dust in a uniform cloud or small puff where needed. For very large gardens. |
| Disease-causing organisms overwinter in garden refuse. Remove all weeds and dead plants and begin a regular spraying program. Spray susceptible plants before there is evidence of damage. Repeat every week or 10 days. | White powdery mildew, wilt, rust, and other leaf and stem disease organisms. |
| Check roses carefully, looking for a black spot on the upper surface of the leaf. Remove and burn any infected leaves, and begin a regular spray program, continuing until Summer. | Black spot, mildew, etc. |

| Eliminate mosquito breeding places (garbage, standing water, weed patches, etc.) Then, spray resting places (flowers, shrubs, dense foliage) | Mosquitoes | Offers a controlled, precise spray. No drenching or waste. Good for a very large yard and a lot of spraying. |
| LATE SUMMER - EARLY FALL |
| SPRAYING JOB | PESTS CONTROLLED | SPRAYERS TO USE |
| Your lawn may be troubled by two types of insects. The first lives in the soil damaging the grass root, while the second attacks from above the ground. You can correct insect problems with a spray program and proper care of your lawn. | Sod, webworms, grub, lawn chinch bugs | Provides a precise, on-target non-drift spray good for soil and lawn pests. Adjust the sprayer for a coarse drenching spray, one that penetrates the ground. Then sprinkle the lawn thoroughly. The size of the sprayer will depend on the size of the yard. |
| This time of year, many weeds are noticeable, while others are simply regrouping for the attack next spring. Both types can be eliminated now with a spray program. | Crabgrass (grassy weeds), dandelions (broadleaf weeds) |
| Lawns that are shaded, watered at night, watered too frequently, or tend to remain wet for long periods are most likely to have disease problems. A spray program will help stop the spread. | Fungi, powdery mildew |
| FALL |

| Spray the foundation around you house, especially in the fall. Crawling insects are less likely to cross this pesticide barrier. Spray just to the point of runoff and spray all the way around the house. Also spray a 2" to 4" band of soil alongside the foundation. | Ants, centipedes, spiders, crickets and water bugs | This applicator, with its control features, places the spray exactly where it should be in just the right amount. |
| YEAR-ROUND |
| SPRAYING JOB | PESTS CONTROLLED | SPRAYERS TO USE |
| If you find the signs of insect attack, you need to apply the proper spray material. | Aphids, cyclamen mites, mealy bugs, millipedes, scales, spider mites, white flies. | A lightweight polyethylene compression sprayer with a capacity of around 1/2-gal. is ideal for houseplants. |
