​Good morning, and when you go outside you will notice it is almost crisp out  Humidity is low.  Going to be an awesome day except for the smoke in the air from the fires.  Stay safe and enjoy.
 
Australia family and friends for August 1, Friday will have rainy conditions around 2 AM.  Their time now at 8:30 AM on Thursday for us, and for them it is 11:30 PM Thursday evening.  Stay dry, stay safe.
 
Last of the tomato diseases.  I hope you are having any of these.  It soon will be producing lots of fruit for you.  I know lots of salsas, juice, pasta sauce, pizza sauce and tomato soup will be processed and canned.  I, myself, love to can.   I will find time to do that when the tomatoes are ready.  I didn’t get to do it last year because of our trip to Australia.  That was a lifetime trip for sure.  I am keeping in touch with family and friends there, which is what we wanted when we went on the trip.  Sightseeing was great, but the family and friends are a lifetime.

White spots on tomato leaves can be caused by sunscald or insect problems. Insects with piercing, sucking mouthparts often leave small white dots behind as they go, where they’ve slurped up all the good stuff out of the leaf cells, leaving them pale and white. It could be thrips or leaf miners.
However, if it’s a tomato disease-related issue, it may be powdery mildew. This fungal disease isn’t usually a huge problem in tomatoes, but it can slow them down and reduce yields by interfering with photosynthesis. Powdery mildew makes the plant leaves look like they’ve been dusted with flour. There may be white spots at the beginning of the infection.
To combat powdery mildew, space plants adequately and prune to maintain good air circulation. It’s okay to remove the infected leaves, but it usually isn’t necessary.
Resistant varieties: ‘Rebelski’ and ‘Geronimo’

Wilting tomato leaves

Tomatoes wilt in extreme heat and weather due to dehydration, but if adequate soil moisture is present, it could be a sign of bacterial wilt.
Bacterial wilt is caused by an organism called Ralstonia solanacearum. It lives in the soil for years and enters the plant through wounds caused by insects, transplanting damage, or other factors. Once in the plant, it fills the portions of the stem that conduct water with slime, choking it off and causing the wilt. The wilt, after all, is merely a symptom of the leaves not getting enough water.
Bacterial wilt is characterized by wilting leaves that stay green. If you cut an infected stem, you may see a brown or yellow slime inside.
Controlling bacterial wilt is best done with cultural methods. Remove and dispose of all infected plant material (don’t compost it) and switch to growing a non-tomato-family crop in that site, such as corn, beans, or squash. While crop rotation often doesn’t help gardeners much with insect pests, it can be beneficial in managing bacterial wilt. Wait at least 3 years before growing tomatoes, peppers, or eggplants in that location.
